Allegro MicroSystems Inc. 2D Hall-Effect Speed And Direction Sensor IC APS12626LLHALT-CA

The APS12626 is a 2D Hall-effect sensor IC for detecting speed and direction in motor and encoder applications, featuring planar and vertical Hall elements that provide quadrature outputs with phase separation independent of magnet pole pitch and air gap. It operates from 2.8 to 5.5 V, is qualified to AEC-Q100 Grade 0 for operation up to 175°C junction temperature, and includes output short-circuit protection. The device is packaged in a 5-pin SOT23-W (LH) surface-mount package, with a 4-layer PCB thermal resistance of 124 °C/W. It supports multiple sensing axis configurations and can restore state after power cycling. The part is RoHS-compliant.
