LP5812DDSDR TI LED Driver | 8-WSON(3x3) | 4-Channel, I2C, 1.8V Logic

Product Overview

The LP5812DDSDR is a high-performance, 4-channel LED driver from Texas Instruments, designed for precise current control and advanced lighting effects. Housed in a compact 8-WSON (3x3 mm) package, it integrates I2C-compatible interface for flexible brightness and pattern programming. With a wide input voltage range of 2.5V to 5.5V and 1.8V logic supply, it is ideal for portable and battery-powered applications. The device supports independent channel control, PWM dimming, and automatic breathing patterns, making it suitable for indicator LEDs, backlighting, and decorative lighting.
