DESCRIPTION
The APS12625 and APS12626 integrated circuits are dual
ultrasensitive Hall-effect latches optimized for use with ring
magnets. They feature both vertical and planar Hall elements
with sensing axes that are orthogonal to one another, providing
90° of phase separation. This phase separation is inherently
independent of magnet pole spacing and air gap. No target
optimization is required, making them extremely flexible and
easy to use.
For example, the ring magnet pole-pitch can be changed without
having to modify the sensor position or other mechanical design
details. Additionally, XY, ZX, and ZY options are available to
work in almost any orientation to the target. The APS12625
features Speed and Direction outputs, while the APS12626 has
quadrature outputs (Channel A/B).
A unique feature allows the host system to restore the correct
state after power-cycling the device (-P option). This reduces
the potential accumulation of lost counts/pulses when the device
wakes up with one or more sensors in its hysteresis region.
