OH44E

Unipolar Hall Effect Switch IC

Order Information

PN OH44E

Operate temperature -40～150℃ Package 1000pcs/bag

General Description: OH44E is a switched Hall-Effect IC which is for

contactless switching applications. The device 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.
