APS13568 Datasheet LED Driver

Manufacturer: Allegro MicroSystems

General Description

The APS13568 is an integrated circuit that combines an ultrasensitive, omnipolar, micropower Hall-effect switch with a linear programmable current regulator providing up to 150 mA to drive high brightness LEDs.

The omnipolar Halleffect switch provides contactless control of the regulated LED current, which is set by a single reference resistor.

This highly integrated solution offers high reliability and ease of design compared to a discrete solution.
