The TLC5924 is a 16 channel constantcurrent sink driver. Each channel has a On/Off state and a 128step 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.
Each constantcurrent output has a precharge FET that enables an improvement in image quality of the dynamicdrive LED display.
The TLC5924 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.
