Product Description

The TLC5940PWP is a 16-channel Constant-current Sink LED Driver with EEprom DOT correction and greyscale PWM control. Each channel has an individually adjustable 4096-step greyscale 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. The dot correction data is stored in an integrated EEPROM. Both greyscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels. The TLC5940PWP 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.
