TLC5923 带有点校正的 16 通道 LED 驱动器

TLC5923 描述

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
