TLC5940RHBR Description

Short technical summary and product information.

The TLC5940RHBR from Texas Instruments is a versatile 16-channel LED driver designed for applications requiring precise brightness control. Each channel features individually adjustable 4096-step grayscale PWM control and a 64-step constant-current sink for dot correction, which helps minimize brightness variations between channels and other LED drivers.

 

This device supports a maximum output current of 120mA per channel and operates with a supply voltage range of 3V to 5.5V. It includes integrated EEPROM for storing dot correction data, accessible via a serial interface. The TLC5940RHBR also incorporates LED open detection (LOD) and thermal error flag (TEF) for enhanced reliability.

 

Packaged in a 32-VQFN (5x5) surface-mount package, the TLC5940RHBR is suitable for various LED driving applications, including display backlighting and general high-current LED drive. Its 30MHz data transfer rate and CMOS level I/O facilitate integration into complex designs.
