A6261 - Protected LED Array Driver

Description

TheA6261 is a linear, programmable current regulator providing up to 100 mA from each of four outputs (LP and LY) to drive arrays of high brightness LEDs.

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

Features

  • AEC-Q100 qualified.
  • Total LED drive current up to 400 mA (LP, LJ, and LY packages) or 300 mA (LJ).
  • Current shared equally up to 100 mA by up to 4 strings (LP and LY).
  • 6 to 50 V supply.
  • Low dropout voltage.
  • LED output short-to-ground and thermal protection.
  • Disable on open LED detection option.
  • Enable input for PWM control.
  • Current slew rate limit during PWM.
  • Current set by reference resistor.
  • Auto.
