AH337  
Single Phase Hall Effect Switch  
„ Features  
„ General Description  
- 4.2V to 28V DC operation voltage  
- Temperature compensation  
- Wide operating voltage range  
- Open drain pre-driver  
AH337 is an 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. The bandgap regulator allows a wide  
operating voltage range.  
- 25mA maximum sinking output current.  
- Package: SIP3, SOT23  
If a magnetic flux density larger than threshold Bop,  
DO is turned on(low). The output state is held until  
a magnetic flux density reversal falls below Brp  
causing DO to be turned off (high).  
„ Applications  
- VCD/DVD loader, CD/DVD ROM  
- Cover detector  
- Speed measurement  
- Home appliances  
- Home safety
