| HALL EFFECT SENOR IC | MAGNETIC SENSOR | OH543 / OH443 / OH443R Hall Latch IC 1. General Description OH543，OH443, OH443R 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 supply voltage, operating temperature, and high load capacity, they perform well in many applications, such as position control, speed detection, and flow detection as a non-contact magnetic sensor. Flat TO-92S, SOT89 (SC23) package style is available. 2.
