TLC5923DAP .

The TLC5923DAP is a 16-channel constant-current LED Sink Driver with dot correction. Each channel has a on/off state and a 128-step adjustable constant current sink (dot correction). The dot correction adjusts the brightness variations between LED, LED channels and other LED drivers. Both dot correction and on/off state are accessible via a serial data interface. A single external resistor sets the maximum current of all 16 channels. The TLC5923 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an over-temperature condition.
