The TLC5923 is a 16 channel constant-current sink driver. 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 overtemperature condition.
