TLC5940 16-Channel LED Driver IC - 10 Pack

$159.95
SKU TLC5940A

Now available from PMD Way is the useful TLC5940 16-Channel LED Driver IC in packs of ten. This is the through-hole friendly version.

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.
