TLC5947DAP TI LED Driver | 32-HTSSOP | 24-Channel, 30mA Constant Current

Product Overview

The TLC5947DAP is a 24-channel, constant-current sink LED driver from Texas Instruments. It is designed for applications requiring high-precision current control and grayscale PWM dimming. Each channel can be independently adjusted with 12-bit (4096 steps) grayscale control and 6-bit (64 steps) global brightness control. The device operates from a 3.0V to 5.5V supply voltage and can sink up to 30mA per channel. The 32-pin HTSSOP package with PowerPAD ensures excellent thermal performance. The TLC5947DAP uses a serial interface for data input, making it easy to daisy-chain multiple devices for large-scale LED systems.
