TLC5944PWPR TI LED Driver | 28-HTSSOP | 16-Ch, Dot Correction, PWM

Product Overview

The TLC5944PWPR is a 16-channel constant-current sink LED driver from Texas Instruments, designed for high-performance display and lighting applications. It features dot correction (DC) and grayscale (GS) control via a serial interface, enabling precise brightness and color management. Housed in a 28-pin HTSSOP package with PowerPAD for enhanced thermal dissipation, it supports up to 50 mA per channel and operates from a 3.0 V to 5.5 V supply. The device integrates a 16-bit shift register, data latches, and constant-current drivers, making it ideal for LED matrix displays, signage, and automotive lighting.
