LP5810BYBHR TI LED Driver | 9-DSBGA (1.43x1.43) | 4-Channel, I2C, 1.8V Logic

Product Overview

The LP5810BYBHR 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 1.8V logic supply, it supports up to 25 mA per channel with low dropout voltage, making it ideal for battery-powered devices. The device features automatic power-save mode, thermal shutdown, and under-voltage lockout, ensuring reliable operation in space-constrained designs.
