Description

The TLC5940 is a 16-channel constant-current sink ED driver. Each channel has an individually adjust-able 4096-step grayscale PWM brightness control nd a 64-step constant-current sink (dot correction).dot correction data is stored in an integratedEEPROM. Both grayscale control and dot correctionare accessible via a serial interface. A single externalresistor sets the maximum current value of all 16channels.

The TLC5940 features two error information circuits.The LED open detection (LOD) indicates a broken or isconnected LED at an output terminal. The thermalerror flag (TEF) indicates an o ertemperature condition.
