A6263 - Protected LED Array Driver

General Description

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.

Key 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.
  • LED string shorted to GND protection.
  • Overtemperature protection with optional thermal derating function.
  • Automotive temperature range.
