Renewable Energy, Power Generation, Isolation Products, Gate Drivers and Current Sense

With oil prices and global warming on the rise, renewable energy is an emerging trend, supported by government agencies with attractive incentives. Renewable energy power generators use power conversion systems such as DC-to-DC or DC-to-AC inverters which require safety and signal isolation solutions.

FEATURES, BENEFITS AND ADVANTAGES Avago’s Isolation Solutions offer an effective means of protection, including maximizing the energy conversion efficiency in the power converters. The ACPL-C78A/C780/C784 isolation amplifier family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the ACPL-C78A/C780/C784. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the ACPL-C78A/C780/C784 was designed to ignore very high common-mode transient slew rates (of at least 10kV/μs).

• 15kV/μs common-mode rejection at VCM = 1000V • Provides precision and stability in high noise motor control environments • Compact, auto-insertable stretched SO-8 package • Saves 30% PCB space compared to the DIP-8 package • Advanced Sigma-Delta A-to-D converter technology • Fully differential amplifier • Wide operating temperature range APPLICATIONS • • • •

Inverter current sensing Motor phase and rail current sensing Switched mode power supply signal isolation General purpose analog signal isolation

The high CMR capability of the ACPL-C78A/C780/ C784 isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control (less “torque ripple”) in various types of motor control applications.

30V P-Channel TrenchFET® Gen III Power MOSFET Sets New Industry First with 2.6mΩ Maximum On-Resistance in SO-8 Footprint Area Vishay Intertechnology has just released the industry's first 30V P-channel power MOSFET in the SO-8 footprint area to boast maximum on-resistance down to 2.6mΩ at a 10V gate drive and 3.75mΩ at 4.5V. With these specifications, the new Vishay Siliconix Si7145DP, latest member of the TrenchFET® Gen III P-channel family, achieves the lowest on-resistance ever for this voltage rating and footprint. Packaged in the PowerPAK SO-8, the Si7145DP will be used as the adaptor switch and for load switching applications in notebook computers and industrial/general systems. Its low on-resistance translates into lower conduction losses, allowing the Si7145DP to do a better job of saving power and prolonging battery life between charges. This capability is especially important in adaptor switches (switching between the adaptor/wall power or the battery power), which are always on and drawing current. ®

The device is 100% Rg, UIS-tested and halogenfree. The next-best 30V P-channel device in the SO-8 footprint available from a competitor features maximum on-resistance of 3.1mΩ at a 10V and 4.3mΩ at 4.5V, meaning 16% and 13% higher than the Si7145DP. In addition to the Si7145DP, Vishay has released several other TrenchFET Gen III P-channel MOSFETs. To achieve even lower RDS(ON) ratings in the PowerPAK SO-8 package, a 20V device is available to reduce conduction losses. It is rated at 1.9mΩ max. @ 10V - Si7137DP. To save space on the PCB, the technology is available in smaller packages such as PowerPAK SC-70 and PowerPAK SC-75, which are ideal for portable or handheld applications.

Energy Solutions: NaPiOn and NaPiCa Sensors NaPiCa sensors

NaPiCa is a Cadmium-free light sensor with spectral response similar to that of the human eye. Design consists of a photodiode with a built-in current amplifier. NaPiCa detects visible light and converts to a photocurrent that is proportional to illumination. Three different models are available in SMD (automatic mounting), through-hole (same design as photoconductive cell) and chip design (miniaturization).

Panasonic Electric Works Corporation of America

NaPiOn and NaPiCa Sensors for Lighting Market

Small multi-lens surface High sensitivity quad element sensor Single chip IC with built-in amplifier and comparator MIPTEC: (Microscopic Integrated Processing Technology)

NaPiOn is a passive infrared (PIR) motion sensor that provides precise occupancy detection for automatic lighting controls. Fully integrated features include a built-in amplifier, comparator, power supply and PIR element. All components are enclosed in a TO-5 metal package offering additional protection from noise interference. A quad sensing element differentiates the NaPiOn and provides more sensitive detection zones than a dual element. Less motion is required by a person in order to activate the sensor output and maintain efficient lighting control.

Four (4) detection models are available: Standard (5m), Slight (2m), Spot (5m) and Long range (10m). Digital output offers design simplification and analog output is flexible to adjust sensor sensitivity. Low power consumption NaPiOn is rated 46ÂľA for battery applications and wherever power consumption needs to be at a minimum. Black and white lenses are offered for aesthetic reasons and both offer equal sensor performance.

NaPiCa is a natural complement to the NaPiOn in energy saving lighting applications. Light sensors are used in conjunction with occupancy sensors for daylight harvesting, where artificial lighting is dimmed in proportion to ambient natural sunlight entering a building. Small size factor for both NaPiCa and NaPiOn components makes design integration easy.

These solutions still come with built-in high voltage switches for a very integrated solution and offer all the same great protection you have come to expect from an NXP SSL driver solution.

For higher power applications (25W to 250W), NXP offers its flagship SSL1750, with its integrated SMPS controller and PFC controller in one chip. The SSL1750 has been demonstrated to work with triac dimmers in 75W applications with very high efficiency and PF numbers. In street light applications, it can deliver 90W with about 90% efficiency.

Combining the Widest Operating Voltage with High Ambient Operating Temperature Range and Low Power Consumption Vishay’s optically isolated IGBT/MOSFET Drivers Feature 32V Maximum Supply Voltage, Combine +110°C Maximum Operating Temperature and 2.5mA Maximum Supply Current for Thermal and Power Efficiency Vishay Optoelectronics has broadened its optocoupler portfolio with two IGBT/MOSFET drivers. The VO3120 has a minimum output current of 2.5A and 0.5A for the VO3150A. Both drivers combine the widest operating voltage with high ambient operating temperature ranges and low power consumption to enable better thermal management and more flexible design choices. Vishay’s VO3120 (2.5A) and VO3150A (0.5A) IGBT/ MOSFET drivers each consist of an LED optically coupled to an integrated circuit with a power output stage that has an operating voltage range of 15V to 32V. The voltage and current supplied by the drivers make them ideal for directly driving IGBTs with ratings up to 800V and 50A for the VO3120 and 20A for the VO3150A. Their industry high operating voltage allows the devices to drive larger modules that typically require a two-sided power supply, thus giving designers more choices in selecting power components. With a high maximum ambient operating temperature of +110°C and their low power consumption of 2.5mA, the VO3120 and VO3150A simplify thermal management by allowing designers to place them in closer proximity to IGBTs and to use smaller heat sinks.

Ramtron Announces 8-Megabit Parallel Nonvolatile F-RAM Memory

Space efficient ball grid array package offers pin-compatible upgrade path for F-RAM. The FM23MLD16 is an 8Mb, 3V, parallel nonvolatile RAM in a 48-pin Fine-Pitch Ball Grid Array (FBGA) package that features fast access, virtually unlimited read/write cycles and low power consumption and is pin-compatible with asynchronous static RAM (SRAM). The FM23MLD16 is a 512Kx16 nonvolatile memory that reads and writes like a standard SRAM. A ferroelectric random access memory or F-RAM is nonvolatile, which means that data is retained after power is removed. It provides data retention for over 10 years while eliminating the reliability concerns, functional disadvantages, and system design complexities of battery-backed SRAM (BBSRAM). Fast write timing and very high write endurance make F-RAM superior to other types of memory. “The 8Mb F-RAM parallel memory and our recently released 4Mb FM22LD16, are designed to meet customer demand for higher density memory for writeintensive data collection applications,” remarks Mike Peters, Ramtron marketing manager. “Both

products are pin-compatible, enabling an easy density upgrade. The FM23MLD16 allows system designers eight times the F-RAM density in an equivalent TSOP-32 package footprint,” adds Peters. FEATURES 8Mbit Ferroelectric nonvolatile RAM • Organized as 512Kx16 • Configurable as 1Mx8 using /UB, /LB • High endurance 100 Trillion (1014) read/writes • NoDelay™ writes • Page mode operation to 33MHz • Advanced high reliability Ferroelectric process SRAM compatible • JEDEC 512Kx16 SRAM pinout • 60 ns access time, 115 ns cycle time Advanced features • Low VDD monitor protects memory against inadvertent writes Superior to battery-backed SRAM modules • No battery concerns • Monolithic reliability • True surface mount solution, no rework steps • Superior for moisture, shock and vibration

Electrode distance 3.2mm (RL1632) Electrode distance 1.6~2.0mm (RL3720W)

The RL/PRL series, Susumu’s long side terminal current sensor chip resistors have shorter and wider resistive elements compared to their conventional short side terminal counterparts. Due to this reason, they have much less parasitic inductance (ESL), hence, less noise (see Figure 1). Figure 2 shows the pulse shape with a longer side terminal chip (left) vs. a shorter side terminal chip.

Leveraging the New LUXEON® Rebel Phosphor Converted (PC) Amber LEDs in Emergency and Warning Vehicle Lighting

Clearly, all the shortcomings are related to the junction temperature of the LED. The traditional Amber LEDs are based on Aluminum Indium Gallium Phosphide (AlInGaP) chip technology, which is highly sensitive to any increase in the LED’s junction temperature. This presented a challenge in the adoption of Amber LEDs in the EWVL market applications. Philips Lumileds has successfully addressed the mentioned general requirements and the shortcomings of the traditional Amber LEDs by introducing the new LUXEON® Rebel Phosphor Converted (PC) Amber LED. From reliability, to color stability and light output, LUXEON® Rebel PC Amber presents the superior and optimum solution for the EWVL market needs. This article introduces the new LUXEON® Rebel PC Amber LED and all its features and advantages over traditional Amber LEDs. Comparisons between

A. Important Features Light Output With a typical luminous flux of 70 lm at DC forward current of 350mA, one LUXEON® Rebel PC Amber LED delivers 2-3 times more flux than one LUXEON® Rebel Amber LED that utilizes the AlInGaP technology. As the junction temperature of an LED increases, its light output decreases. This negative effect has been one of the shortfalls of the traditional AlInGaP Amber LEDs. Figure 1 illustrates the degradation in the relative light output as a function of the junction temperature for both the AlInGaP Amber and the new LUXEON® Rebel PC Amber LEDs. At higher junction temperature, the LUXEON® Rebel PC Amber light output degrades at a significantly lower rate than the traditional AlInGaP Amber LEDs. From an application standpoint, this will result in more light at high junction temperatures, a lower

Figure 1. Light Output Degradation as a Function of Junction Temperature

Luminous Efficacy and Electrical Power Consumption One of the most important factors in LED lighting is the luminous efficacy produced by the system. The luminous efficacy is the ratio of the light output (in lm) to the consumed electric power (in W). With a typical power consumption of 1.1W at a DC forward current of 350mA, the LUXEON® Rebel PC Amber offers remarkable typical luminous efficacy of 63.5 lm/W. Figure 2 provides a comparison between the luminous efficacies of the AlInGaP Amber LEDs and the new LUXEON® Rebel PC Amber LED. It is especially important to notice that at high temperatures (above 25°C), the new PC Amber has remarkably higher luminous efficacy compared to the AlInGaP Amber. This is an important factor for most outdoor and emergency lighting applications in hot environments. According to Figure 2, at an extreme junction temperature of 150°C, the luminous efficacy of conventional AlInGaP Amber LED is 10 lm/W. At the same junction temperature, the luminous efficacy of the new LUXEON® Rebel PC Amber is 32 lm/W. This is a three-fold increase compared to the luminous efficacy of the AlInGaP Amber. 70 60 Luminous Efficacy (lm/W)

The hot/cold factor of the LUXEON Rebel PC Amber LED is 2.1 times higher than the traditional LUXEON® Rebel Amber LED. ®

The Droop Effect An increase in the LED DC forward current results in an increase in its luminous flux. An artistic visualization of this, along with an imaginative linear approximation is provided in Figure 3. The increase in the luminous flux is non-linear, caused by the so-called “droop effect.” As shown in Figure 4, the new LUXEON® Rebel PC Amber exhibits more linear increase in the relative luminous flux than the AlInGaP Amber does, resulting in more light output at high currents. This is a particularly important factor for EWVL applications, where maximum light at high DC forward currents is desirable. Moreover, the number of LUXEON® Rebel PC Amber LEDs required to obtain a specific light output at high drive currents will Droop Effect

The hot/cold factor is the ratio of the LED usable flux at an operational junction temperature (hot) to that at a junction temperature of 25°C (cold). In this article, the hot usable flux is calculated at a junction temperature of 85°C, driven at the nominal DC forward current of the LED. The goal is to have the hot/cold factor as high as possible (close to 1). Table 1 provides a numerical comparison between the hot/cold factors of LUXEON® Rebel PC Amber LED and the LUXEON® Rebel Amber LED.

Normalized Luminous Flux (lm)

This will result in more light output for the same consumed electrical power. Since most EWVL applications are battery operated, improved luminous efficacy prolongs the battery life.

Since most EWVL applications involve outdoor operations at high ambient temperatures, the color stability of the new LUXEON® Rebel PC Amber LED over junction temperature variations puts it in an advantageous position for EWVL applications. In addition, the color stability of LUXEON® Rebel PC Amber with junction temperature changes keeps the color coordinates of its three color bins within the SAE and ITE specified ranges. This will result in more reliability for EWVL applications leveraging the LUXEON® Rebel PC Amber LEDs. C. LUXEON® Rebel PC Amber Against Competing Amber LEDs Table 2 provides numerical comparison of the light output, luminous efficacy and hot/cold factor of the new LUXEON® Rebel PC Amber against those of competing Amber LEDs.

Conclusion

NEC Electronics’ µPD78F8024 Microcontroller Unit (MCU) is a constant-current driver with four independent channels to control multiple LEDs within the same system. With an input voltage range of 9–38V, it supports both buck and boost topologies. This is ideal for EWVL applications running on 12V or 24V batteries. Each constant current driver uses an independent hysteretic regulator controller with a switching frequency up to 1MHz. The flash microcontroller can control each channel through 8-bit Pulse Width Modulation (PWM) signals to enable dimming, flashing, and strobe sequences. In addition, the NEC µPD78F8024 MCU supports LED failure detection, custom flashing sequences and color management algorithms. Finally, it allows using temperature sensors and light sensors to provide intelligent thermal and power management.

The emerging EWVL market requirements and the benefits of LUXEON® LED technology have been discussed. The new LUXEON® Rebel PC Amber has also been introduced and discussed. The key advantages of this new InGaN-based Amber technology involve less color shift with junction temperature, improved hot/cold factor, higher usable flux and luminous efficacy and higher LED efficiency than those of the traditional AlInGaP Amber and competing Amber LEDs. The NEC µPD78F8024 MCU has also been selected as the constant-current LED driver with intelligent features. Together, the new LUXEON® Rebel PC Amber LED and the NEC µPD78F8024 MCU, both available through Future Lighting Solutions, satisfy all the needs of the EWVL market.

Typical applications of the LUXEON® Rebel PC Amber LEDs and the NEC µPD78F8024 MCU in EWVL applications include light bars, beacons and directional arrows.

Covering All the ISM Bands with Leading Edge Transceivers By Larry Hall - Advanced Engineer, Future Electronics

Wireless interfaces are becoming more popular on all types of electronic products. Communications standards allow the user to choose the complexity of the wireless RF system and whether it needs to be able to communicate with other suppliers’ products.

standard uses the IEEE 802.15.4 for the Physical and MAC layer definitions. The remaining layers are defined by the ZigBee Alliance. Customization on the Application Layer allows users to develop a wide range of applications based on the ZigBee protocol.

Wireless connections are being used to a greater degree in machine-to-machine interfaces. The reduction of wires is a great benefit for a wide range of applications such as command/control, metering, data logging and home/office/factory automation. This allows more convenient placement of a system instead of being dependent on the restrictions of many cables.

Zigbee PRO is the latest software stack for applications requiring the latest compatibility and capability.

The communication range depends on many factors in the surrounding environment. Walls and ceilings will reduce the range of the RF system. Other interference can come from radios, televisions, computers and other wireless devices inside and outside the band that the particular system is using. Microchip has hardware and software products that cover the ISM bands of 433MHz, 868MHz, 915MHz and 2.4GHz that are available today for wireless networks. MRF49XA is one of the newest transceiver parts and enables communication in the 433, 868 and 915MHz bands. These parts are simple to use and require only a few external components to build a system. MRF24J40 is the RF chip that is the building block part for the MRF24J40MA and MRF24J40MB modules. These parts communicate in the 2.4GHz ISM band and coexist with several other wireless devices in this band. There are software stacks that can be used to create Star, Meshing, Zigbee 2006® and Zigbee PRO® solutions. MiWi P2P is the smallest code footprint and allows a Star or Peer-to-Peer configuration to be created. MiWi P2P can be used for wire replacement applications using a wide variety of 8/16/32-bit PIC processors and a simple software interface that can be created from the available libraries. MiWi enables routing of information to the neighboring radios with up to 4 hops. The stack is a little larger as compared to the MiWi P2P but can greatly extend the range of the radio communication. Zigbee 2006 is implemented as an industry standard compatible platform based on the standards set by the ZigBee Alliance. The ZigBee
