OH137
Unipolar Hall Effect Switch IC
Order Information
PN OH137
Operate temperature -40~85℃ Package 1000pcs/bag
General Description: OH137 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.
