The TLC5921DAPR is a 16-channel constant-current sink LED driver designed by Texas Instruments. Each output channel can sink 1 to 80 mA, set by an external resistor, with a typical constant-current accuracy of ±1% and a maximum of ±4% across all bits. The driver requires a minimum output voltage of 0.6 V to maintain regulation.
This device is suitable for applications requiring multiple LED channels with consistent brightness, such as signage, display backlighting, and indicator arrays. The constant-current architecture ensures uniform light output regardless of variations in LED forward voltage.
The TLC5921DAPR is housed in a 32-pin HTSSOP package, supporting surface-mount assembly for compact designs.
