Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer flexible 2D magnetic sensing with vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, allowing for easy integration and design modifications. The devices are available with Speed and Direction outputs (APS12625) or Quadrature outputs (APS12626). A unique power-cycling restore feature (-P option) prevents lost counts/pulses. These sensors are automotive-grade, qualified per AEC-Q100 for operation up to 175C, and feature output short-circuit protection and high magnetic sensitivity, operating from 2.8 to 5.5 V.
