TLC5971PWPR Description

Short technical summary and product information.

The Texas Instruments TLC5971PWPR is a versatile 12-channel LED driver designed for applications requiring precise control of LED brightness and color. It features 16-bit grayscale control for each channel, allowing for up to 65,536 steps of brightness adjustment, and 7-bit global brightness control for each color group.

 

This device provides a constant current output of 60mA per channel with high accuracy, ensuring consistent illumination. It supports a power supply voltage range from 3V to 5.5V for direct power and 6V to 17V with its internal 3.3V linear regulator. The LED supply voltage can be up to 17V.

 

Packaged in a 20-HTSSOP, the TLC5971PWPR is suitable for surface mount applications. It operates reliably within an ambient temperature range of -40°C to 85°C and includes features such as thermal shutdown for protection. Its topology is based on a shift register, enabling unlimited device cascading for larger LED arrays.

 

Applications for the TLC5971PWPR include RGB LED cluster lamps and various display systems where precise color mixing and brightness control are essential.
