A1126  
Chopper Stabilized Omnipolar Hall-Effect Switch  
Description  
Features and Benefits  
• Omnipolar operation  
The A1126 integrated circuit is an omnipolar, ultrasensitive  
Hall-effect switch with a digital output. This device has an  
integrated regulator permitting operation to 24 V.  
• Low switchpoint drift  
• Superior temperature stability  
• Insensitive to physical stress  
• Reverse battery protection  
• Robust EMC capability  
• Robust ESD protection  
Thisdeviceisespeciallysuitedforoperationthroughextended  
temperature ranges, up to 150°C. Superior high-temperature  
performance is made possible through an Allegro® patented  
dynamic offset cancellation, which reduces the residual offset  
voltage normally caused by device overmolding, temperature  
excursions, and thermal stress.  
Packages:  
The A1126 Hall-effect switch includes the following on a  
single silicon chip: voltage regulator, Hall-voltage generator,  
small-signal amplifier, chopper stabilization, Schmitt trigger,  
and a short circuit protected open-drain output. Advanced  
BiCMOSwaferfabricationprocessingisusedtotakeadvantage  
of low-voltage requirements, component matching, very low  
input-offset errors, and small component geometries.

Not to scale  
The omnipolar operation of the A1126 allows activation with  
either a north or a south polarity field of sufficient strength.  
In the absence of a magnetic field, the output is off. This  
patented magnetic-polarity–independence feature makes  
this device an excellent replacement for reed switches, with  
improved ease of manufacturing, because the A1126 does not
