3 Description
The LP5814 is a 4-channel RGBW LED driver with
autonomous animation engine control. The device
has ultra-low operation current with 0.1μA (typical) in
shutdown mode, 0.1mA (typical) when enable device
and 0.2mA (typical) when illuminate LEDs.
Both analog dimming and PWM dimming methods are
adopted to achieve powerful dimming performance.
The output current of each LED can be adjusted
with 256 steps from 0.1mA to 25.5mA or 0.2mA to
51mA. The 8-bits PWM generator enables smooth
and audible-noise-free dimming control for LED
brightness.
The autonomous animation engine can significantly
reduce the real-time loading of controller. Each LED
can be configured through the related registers to
realize vivid and fancy lighting effects.
