TLC5924 (ACTIVE)

16-Channel LED Driver w/DOT Correction & Pre-Charge FET

 

Description

The TLC5924 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.

Each constant–current output has a pre–charge FET that enables an improvement in image quality of the dynamic–drive 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 over–temperature condition.
