Description

The TLC5941PWPR 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 TLC5941PWPR 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
