TLC5945PWPR

16通道LED驱动器，具有点校正和灰度PWM控制 16-CHANNEL LED DRIVER WITH DOT CORRECTION AND GRAYSCALE PWM CONTROL

The TLC5945 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. The dot correction adjusts the brightness variations between LED channels and other LED drivers. Both grayscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels.

The TLC5945 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.
