TLC5947RHBR Description

Short technical summary and product information.

The TLC5947RHBR from Texas Instruments is a 24-channel, constant-current sink LED driver. Each channel provides 12-bit (4096 steps) PWM grayscale control, allowing for precise brightness adjustment. The device supports a constant-current sink capability of up to 30mA per channel and operates with a VCC supply voltage ranging from 3.0V to 5.5V.

 

Key features include a 4-MHz internal oscillator, a 30-MHz standalone data transfer rate, and thermal shutdown protection. The constant-current accuracy is typically ±2% channel-to-channel and device-to-device. The TLC5947RHBR is designed for applications such as static LED displays, message boards, and amusement illumination.

 

This LED driver is available in a 32-VQFN (5x5 mm) surface-mount package. It is suitable for applications requiring multiple individually controlled LED channels with high-resolution grayscale control.
