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
