IC TLC5940 LED DRIVER PWM CONTROL 28-DIP COM23

Fr3,000

The TLC5940 is a 16-channel constant-current sink LED driver. Each channel has an individually adjust able 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. The dot correction data is stored in an integrated EEPROM. 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 TLC5940 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.
