TLC5924RHBT
具有点校正功能与预充电 FET 的 16 通道 LED 驱动器 32-VQFN -40 to 85
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.
