A6263 Datasheet Protected LED Array Driver

Manufacturer: Allegro MicroSystems

Datasheet Details

The A6263 is a linear, programmable current regulator providing up to 100 mA from each of 4 outputs to drive arrays of high brightness LEDs.

Outputs can be connected in parallel or left unused, as required.

The regulated LED current from each output, accurate to 5%, is set by a single reference resistor.
