Product 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.
