OH137 Unipolar Hall Effect Switch - (AD36225)

Description:

The OH137 Hall switch IC internally consists of a reverse voltage protection device, a voltage regulator, a Hall voltage generator, a differential amplifier, a Schmitt trigger, and an open collector output level. When the magnetic flux density (B) is greater than the threshold Bop, the output pin is turned on (low). When B < Brp, the output pin is turned off.
