Unipolar Hall Effect IC In SMD Package

Order Information

OH543

Operate temperature

-40～150℃

Package 1000pcs/reel

General Description: OH543 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.
