TLC5943RHBT TI LED Driver | 32-VQFN (5x5) | 16-Ch, 12-Bit PWM, 30mA

Product Overview

The TLC5943RHBT is a 16-channel, constant-current sink LED driver from Texas Instruments, designed for high-precision LED control in demanding applications. Each channel provides 12-bit (4096 steps) PWM grayscale control with a constant current range of 0.5 mA to 30 mA, ensuring uniform brightness and color mixing. The device operates from a 3.0V to 5.5V supply and features a 30 MHz serial data interface for daisy-chaining multiple devices. Housed in a compact 32-VQFN (5x5 mm) package, it is ideal for space-constrained designs.
