Automotive grade hall effect latch ALLEGRO APS12626LLHALX-BFP with ISO 26262 and AEC Q100 certification
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer flexible 2D magnetic sensing with integrated vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. These devices are easy to use, require no target optimization, and support various orientations (XY, ZX, ZY). The APS12625 provides Speed and Direction outputs, while the APS12626 offers Quadrature outputs. A unique power-cycling restore feature (-P option) minimizes lost counts/pulses. They are automotive grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V with high junction temperature capability.
