Package:
SOT-23W
Key Attributes
Model Number:
APS12626LLHALT-CF
Product Description
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They offer 2D magnetic sensing capabilities through integrated vertical and planar Hall elements, providing 90 phase separation that is independent of magnet pole spacing and air gap. This design eliminates the need for target optimization, offering flexibility in mechanical design. The APS12625 provides Speed and Direction outputs, while the APS12626 features Quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) minimizes lost counts/pulses. These devices are automotive-grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V.
