OH401 - HALL EFFECT SENOR

Download the OH401 datasheet PDF. This datasheet also covers the OH4S variant, as both devices belong to the same hall effect senor family and are provided as variant models within a single manufacturer datasheet.

General Description

OH4S series unipolar hall IC includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output.

Key Features

  • 4V to 30V DC operation voltage.
  • Open-Collector pre-driver.
  • Reverse Polarity Protection.
  • Respond to a single-pole (North or South).
  • High load capacity.
  • anti-environmental stress 3.

| HALL EFFECT SENOR IC | MAGNETIC SENSOR | OH4S / OH4N / OH401 Unipolar Hall IC 1. General Description OH4S series unipolar hall IC includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. It detects the changes of the Magnetic field and outputs a digital voltage signal. With the typical feature of a wide range of working voltage, operating temperature, and high load capacity, OH4N series ICs perform well in many applications, such as position control, speed detection, and flow detection as a non-contact magnetic sensor. 2.
