A6263 Protected LED Array Driver

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 resi.

A6263 Features

* ▪ AEC-Q100 qualified ▪ Total LED drive current up to 400 mA ▪ Current shared equally up to 100 mA by up to 4 strings ▪ Wide input voltage range of 6 to 50 V for start/stop, cold crank, and load dump requirements ▪ Low dropout voltage

* LED current levels set by single reference resistor
