The TLC5940 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. The dot correction data is stored in an integrated EEPROM. Both grayscale control and dot correction are accessible through 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.

LED-FRAME-DESIGNER — LED Frame Designer

LED Frame Designer Software allows the user to individually control the Dot Correction and PWM dimming levels for each LED on the TLC59xx EVM. The software also allows the user to program and play multiple LED “frames” to create different lighting patterns on the EVM.
