AH337

SINGLE PHASE HALL EFFECT SWITCH

Description

Pin Assignments

(Top View)

AH337 is an unipolar Hall-Effect sensor 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. The band-gap regulator allows a wide operating

voltage range.

(Top View)

When the magnetic flux density (B) is larger than operate

point (Bop), output is switched on (OUT pin is pulled low).

The output state is held on until a magnetic flux density falls

below Brp. When B is less than Brp, the output is switched

off.
