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.
