Description

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.
