OH443UnipolarHallEffectSwitch

OH443 Unipolar Hall Effect Switch IC

General Description:

Part No.: OH443   

Operate temperature: -40～150℃ 

Package:1000pcs/Bag

 

OH443 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 an open-collector output. It detects the changes of Magnetic field and output a digital voltage signal. With the typical feature of wide range of working Voltage, operate temperature and high load capacity, OH443 performs well in many applications, such as position control, speed detection and flow detection as a non-contact magnetic sensor.
