TLC5947RHBT Description

Short technical summary and product information.

The TLC5947RHBT 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 is capable of delivering up to 30mA per channel and supports LED power-supply voltages up to 30V, with a VCC range of 3.0V to 5.5V.

 

Key features include a high data transfer rate of 30MHz in standalone mode and 15MHz when cascaded. It incorporates a 4MHz internal oscillator and thermal shutdown protection. The constant-current accuracy is typically ±2% channel-to-channel and device-to-device. The TLC5947RHBT is designed for applications such as static LED displays, message boards, and amusement illumination.

 

This component is available in a 32-VQFN (5x5 mm) exposed pad package and is designed for surface mounting. It operates within an ambient temperature range of -40°C to 85°C.
