TLC5971RGET TI LED Driver | 24-VQFN (4x4) | 16-Ch, 50mA, PWM Dimming

Product Overview

The TLC5971RGET is a 16-channel constant-current sink LED driver from Texas Instruments, designed for high-precision LED control. It features a 16-bit PWM grayscale control for each channel, enabling smooth and accurate brightness adjustment. The device operates from a supply voltage of 3.0V to 5.5V and can sink up to 50mA per channel. It is housed in a compact 24-VQFN (4x4mm) package, making it ideal for space-constrained applications. The TLC5971RGET supports a serial interface for data communication, allowing daisy-chaining of multiple devices.
