4 x 3 matrix RGB LED driver with I2C and auto animation control

The LP5812 is a

4 × 3 matrix RGB LED driver with

autonomous animation engine control. The device has ultra-low normal

operation current with 0.4mA (typical) when illuminate LEDs.

The time-cross-multiplexing (TCM)

structure is adopted, which uses 4 output pins to control 12 LED dots individually. Both

high-side scan switch and low-side current sink are contained in one output. The total

solution size are minimized for space limited system.

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. The device can generate

6MHz clock signal and use it for synchronizing the lighting effects among multiple devices.
