TLC59461PWPR TI LED Driver | 28-HTSSOP | 16-Ch, 50mA, PWM Dimming

Product Overview

The TLC59461PWPR is a 16-channel constant-current sink LED driver from Texas Instruments, designed for high-precision current control and PWM dimming. Housed in a 28-pin HTSSOP package with PowerPAD for enhanced thermal performance, it delivers up to 50 mA per channel with 7-bit global brightness control and 8-bit individual dot correction. The device operates over a wide voltage range (3.0V to 5.5V) and features a serial interface for daisy-chaining multiple drivers, making it ideal for applications requiring high-density LED control.
