TLC5947DAPRG4 Description

Short technical summary and product information.

The TLC5947DAPRG4 from Texas Instruments is a 24-channel, constant-current sink LED driver. Each channel features 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 supply voltage (VCC) ranging from 3.0V to 5.5V.

 

Key electrical characteristics include a 4MHz internal oscillator and data transfer rates of up to 30MHz in standalone mode. The constant-current accuracy is typically ±2% channel-to-channel and device-to-device. The LED power-supply voltage can be up to 30V.

 

Designed for applications such as static LED displays, message boards, and amusement illumination, the TLC5947DAPRG4 includes a thermal shutdown (TSD) function for over-temperature protection. It operates within a temperature range of -40°C to 85°C.

 

The TLC5947DAPRG4 is available in a 32-pin HTSSOP package, designed for surface mounting.
