TLC5973D TI LED Driver | 8-SOIC | 3-Channel, Constant Current

Product Overview

The TLC5973D from Texas Instruments is a 3-channel, constant-current sink LED driver designed for high-brightness LED applications. It features a 3-wire serial interface for daisy-chain operation, enabling control of multiple devices with minimal I/O pins. The device operates from a supply voltage of 3.0V to 5.5V and provides up to 120 mA per channel with adjustable current via an external resistor. The TLC5973D is available in an 8-pin SOIC package, making it suitable for space-constrained designs.
