TLC5946PWPR TI LED Driver | 28-HTSSOP | 16-Channel, 12-Bit PWM

Product Overview

The TLC5946PWPR is a 16-channel, constant-current sink LED driver from Texas Instruments (TI). Each channel has an individually adjustable 12-bit PWM brightness control and a 6-bit global brightness control. The device operates from a 3.0V to 5.5V supply and can sink up to 120 mA per channel. It features a serial interface for data transfer and supports dot correction and grayscale control. The 28-HTSSOP package offers a compact solution for high-density LED applications.
