3 Description
The TLC5940-EP 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 via a serial interface. A
single external resistor sets the maximum current
value of all 16 channels.
The TLC5940-EP 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.
