Lighting Control
Making a smart home smarter.
Integrating power and intelligence.
From appliances to lighting, monitoring and controlling home energy usage is easier than ever with wireless and power line communications that connect meters to the energy-consuming devices.
High-current LED Driver Microcontroller (µPD78F8024 / µPD78F8025)
With NEC Electronics’ intelligent constant high-current driver and microcontroller (uPD78F802x), designers can build intelligent LED lighting systems that can be networked both wirelessly and through power lines. The uPD78F802x devices feature a dedicated 4-channel constant current driver for high-brightness LEDs and an integrated 8-bit microcontroller to manage communication needs.
