LP5812CYBHR TI LED Driver | 9-DSBGA (1.43x1.43) | 4-Channel, I2C, 1.8V Logic

Product Overview

The LP5812CYBHR is a high-performance, 4-channel LED driver from Texas Instruments, designed for portable and compact applications. Housed in a tiny 9-DSBGA (1.43x1.43 mm) package, it integrates I2C-controlled constant current sinks with programmable brightness and blinking patterns. Operating from a 2.5V to 5.5V supply, each channel can sink up to 25 mA with 1.8V logic compatibility, making it ideal for battery-powered devices. The device features ultra-low quiescent current (0.5 µA in shutdown) and supports PWM dimming for smooth lighting effects.
