Lumissil IS31FL329x LED Drivers
Lumissil IS31FL329x LED Drivers are 3-, 6-, and 9-channel LED drivers. These LED drivers consume less than 400µA when fully operational and only 0.3µA when placed into sleep mode. Each LED channel sinks up to 40mA with an accuracy of ±5% between channels and parts. These LED drivers have a dedicated 12-bit PWM register for each channel that enables accurate color mixing of the Red, Green, and Blue LEDs. The IS31FL329x LED drivers with an integrated “auto breath” engine will create gamma-corrected fade ON/Off transition cycles over some time. These devices are suitable for battery-powered IoT applications such as wearables, BLUETOOTH® appliances, AI speakers, personal grooming, and medical devices.
