TLC5973DR TI LED Driver | 8-SOIC | 3-Channel, Constant Current

Product Overview

The TLC5973DR 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 (SDI, SCLK, LATCH) for daisy-chaining multiple devices, making it ideal for large-scale LED displays and signage. The device operates over a wide supply voltage range of 3V to 5.5V and provides adjustable output current up to 120 mA per channel via an external resistor. The TLC5973DR is available in a compact 8-SOIC package, offering a space-saving solution for LED control.
