OH3144 Unipolar Hall IC Datasheet

Product description

OH3144 Hall switches IC internally consists of reverse voltage protection device, voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger, and the open collector output level, which can change magnetic field signals into a digital voltage output. With the typical feature of small size and stable performance, OH3144 is widely used in all kinds of position control, speed detection, flow detection occasions as a non-contact switch.

Features
