OH41 OH41A Hall effect latch IC datasheet

Product description

OH41 OH41A Hall-effect Latching Switch IC is composed of a reverse protector, voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger, and an open-collector output on a single silicon chip. It can convert the magnetic field signal into a digital voltage output in response to N and S alternating magnetic field.

 

Features

  • 4.5V to 24V DC operation voltage
  • Open-Collector sinking type
  • 25mA maximum sinking output current.
  • Reverse Polarity Protection
  • Good temperature performance

Applications

  • The brushless DC motor internal reversing
  • The motor speed and direction detection
  • The motor of the electric bicycle, power-assisted device
  • Speed sensor, counter
  • The flow sensor, flow meter
  • The automotive odometer, speed sensor
