TLC6C5748QDCARQ1 TI LED Driver | 56-HTSSOP | 48-Ch, 5.5V, 50mA

Product Overview

The TLC6C5748QDCARQ1 is a 48-channel constant-current LED driver from Texas Instruments, designed for automotive and industrial lighting applications. It integrates a shift register, latch, and current sink for each channel, enabling precise control of LED brightness and patterns. The device operates from a 3.0V to 5.5V supply and provides up to 50mA per channel, with global brightness control via an external resistor. The 56-pin HTSSOP package offers a compact solution for high-density LED arrays.
