TITLC5940
Overview
The TLC5940 is a 16-channel, constant-current sink LED driver with 12-bit grayscale PWM control and 6-bit dot correction. It supports high-voltage outputs up to 17V and features a 30MHz serial interface for daisy-chaining multiple devices in high-density display applications.
Why Choose This Part
The integrated EEPROM allows for permanent storage of dot correction values to compensate for LED brightness variations without software overhead. It includes built-in diagnostics such as LED Open Detection and Thermal Error Flags to ensure system reliability in demanding thermal environments.
Applications
Key Specifications
Getting Started
Evaluation can be performed using the TLC5940EVM-106 evaluation module. For custom designs, ensure the thermal pad is properly soldered to a ground plane to manage heat dissipation when sinking up to 120mA per channel.
