TLC5971RGER TI LED Driver | 24-VQFN (4x4) | 12-Ch, 16-bit PWM, 3.0-5.5V

Product Overview

The TLC5971RGER is a 12-channel, constant-current sink LED driver from Texas Instruments, designed for high-precision lighting applications. It features a 16-bit (65,536 levels) PWM grayscale control for each channel, enabling smooth and accurate brightness adjustments. The device operates from a supply voltage of 3.0V to 5.5V and provides a constant current range of 0.5mA to 35mA per channel, set via an external resistor. The TLC5971RGER is housed in a compact 24-pin VQFN (4x4mm) package, making it suitable for space-constrained designs. It supports a serial interface (SDI, SCLK) for data input and can be cascaded for multiple device control. The device also includes thermal shutdown and error detection features for reliable operation.
