LP5811AYBHR TI LED Driver | 12-DSBGA (1.84X1.43) | 4-Channel, I2C, 1.5V-5.5V

Product Overview

The LP5811AYBHR from Texas Instruments is a high-performance, 4-channel RGB LED driver designed for portable and wearable applications. It features an I2C-compatible interface, ultra-low quiescent current, and a compact 12-DSBGA package (1.84mm x 1.43mm). The device integrates a charge pump for efficient operation from a single Li-ion battery, supporting output voltages up to 5.5V. With independent channel brightness control and programmable patterns, it enables vibrant lighting effects while minimizing power consumption.
