OH137 Overview
OH37 Series Hall-effect ICs response to S pole from a permanent magnet or an electromagnet. They internally consist of a reverse voltage protection device, voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger, and the open collector output level. While the magnetic flux density (B) is larger than the threshold Bop, the OUT pin turns on (low), when B < Brp, the OUT pin goes into “ off...
