Description

OH513 Hall effect Latch Switch IC integrates hall element and signal processing circuit in one silicon chip, including a reverse protector, voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger and an open-collector output. It can work with the multi-polar magnetic ring and alternating magnetic fields. OH513 has better anti-interference ability and the output waveform duty ratio is little affected by external temperature and alternating magnetic field.

Features

  • High reliability
  • High sensitivity
