General

General Description

Description

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.
