| 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. 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. Applications - The brushless DC motor, DC fans, DC water pump - The home appliance control panel sewing equipment, textile machinery - speed sensor, position detecting, counting and - The auto-ignition, safety alarm device 4.
