The TLC59401 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 TLC59401 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 over-temperature condition.
