Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They feature orthogonal vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. This allows for flexible system design without target optimization. The APS12625 offers Speed and Direction outputs, while the APS12626 provides quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) prevents lost counts/pulses. These devices are ISO 26262 / ASIL A compliant, operate from 2.8 to 5.5 V, and are automotive grade/qualified per AEC-Q100 up to 175C junction temperature.
