OH37 - Unipolar Hall-effect

General Description

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.

Key Features

Respond to a South pole.
4V to 24V DC operation voltage.
25mA maximum sinking output current.
Open-Collector pre-driver.
Reverse Polarity Protection 3.

| HALL EFFECT SENOR IC | MAGNETIC SENSOR | OH37 / OH137 Unipolar Hall-effect IC 1. General Description 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 ” state. SIP and SMD types are available. 2. Features ⚫ Respond to a South pole ⚫ 4V to 24V DC operation voltage ⚫ 25mA maximum sinking output current. ⚫ Open-Collector pre-driver ⚫ Reverse Polarity Protection 3.
