TLC5941-Q1
带有像点修正与灰度 PWM 控制的汽车类 16 通道 LED 驱动器
The device is a 16-channel, constant-current sink, LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step constant-current sink dot correction, which both are accessible via a serial interface. This device features two fault diagnostic 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.
The TLC5941-Q1 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.
