OH177

Bipolar Hall Effect Switch IC

Order Information

PN OH177

Operate temperature

-40～85℃ Package 1000pcs/bag

General Description: OH177 bipolar Ic 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.
