APS12628

Overview

The APS12627 and APS12628 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.

  • Flexible and easy-to-use sensor for motors/encoders
  • ISO 26262 / ASIL B functional safety compliance
  • Fault pin provides additional safety by indicating certain fault conditions
  • 2D magnetic sensing via planar and vertical Hall elements □ Quadrature independent of magnet pole pitch and air gap-no target optimization required □ Works in almost any orientation to the target (XY, XZ, and ZY options)
  • Two signal paths eliminate sampling delay
  • Output update rate of 4.0 µs, 10× faster than previous generation-ideal for applications requiring fast response times
  • Reduces accumulation of lost counts/pulses □ System can restore correct state after power-cycling (-P option)
  • Dual outputs of quadrature or speed/direction signals
  • High magnetic sensitivity
  • Optimized for applications with regulated power rails □ Operation from 2.8 to 5.5 V Continued on the next page… PACKAGE 5-Pin SOT23-W (Suffix LH) Not to scale
