Hall effect latch sensor ALLEGRO APS12625LLHALT-BF with power cycling restoration and multiple sensing axis options
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They feature integrated vertical and planar Hall elements with orthogonal sensing axes, providing 90 of phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, offering flexibility in mechanical design. The devices provide dual outputs: the APS12625 offers Speed and Direction outputs, while the APS12626 provides quadrature outputs (Channel A/B). A unique power-cycling restoration feature (-P option) minimizes lost counts/pulses. These automotive-grade ICs operate from 2.8 to 5.5 V and are qualified for junction temperatures up to 175C.
