TLC5947DAPR Description

Short technical summary and product information.

The TLC5947DAPR from Texas Instruments is a versatile 24-channel LED driver IC designed for applications requiring precise illumination control. Each of its 24 constant-current sink outputs can be individually adjusted with 12-bit (4096 steps) pulse-width modulated (PWM) grayscale control. This allows for detailed dimming and color mixing.

 

The device operates with a supply voltage ranging from 3.0V to 5.5V and can drive LEDs with a power-supply voltage up to 30V. Each channel provides a constant current of up to 30mA, with typical channel-to-channel accuracy of ±2%. The TLC5947DAPR features a 4MHz internal oscillator and a data transfer rate of up to 30MHz, enabling efficient serial communication for grayscale data updates.

 

Designed for surface mounting, the TLC5947DAPR comes in a 32-PowerTSSOP package. Its applications include static LED displays, message boards, amusement illumination, and TV backlighting, where consistent and controllable LED output is crucial. The integrated thermal shutdown function provides protection against over-temperature conditions.
