LP5812DYBHR TI LED Driver | 9-DSBGA (1.43x1.43) | 4-Channel, I2C, 1.8V Logic

Product Overview

The LP5812DYBHR from Texas Instruments is a high-performance, 4-channel RGB LED driver designed for portable and wearable applications. Housed in a compact 9-DSBGA package (1.43 mm x 1.43 mm), it integrates I2C-controlled constant current sinks with programmable brightness and color mixing. Operating from a 2.5V to 5.5V supply, each channel can sink up to 25 mA with 1% accuracy, enabling precise LED control. The device features ultra-low quiescent current (0.5 µA in shutdown) and supports PWM dimming up to 32 kHz for flicker-free operation.
