LP5811CDRRR TI LED Driver | 12-WSON(3X3) | 4-Channel, I2C, 1.5V-5.5V

Product Overview

The LP5811CDRRR is a high-performance, 4-channel constant-current LED driver from Texas Instruments, designed for precise current control and flexible dimming. Housed in a compact 12-WSON (3x3 mm) package, it integrates I2C interface for easy configuration and supports a wide input voltage range from 1.5V to 5.5V. Each channel can sink up to 25.5 mA with 8-bit resolution, enabling smooth brightness adjustment. The device features low quiescent current (0.5 µA typical in shutdown) and built-in thermal shutdown protection, making it ideal for portable and space-constrained applications.
