Micropower Ultrasensitive Hall Effect Switch  
Features and Benefits  
▪ 1.65 to 3.5 V battery operation  
▪ Low supply current  
Description  
The A1171 integrated circuit is an ultrasensitive, Hall effect  
switch with latched digital outputs and either unipolar or  
▪ High sensitivity, BOP typically 30 G (3.0 mT)  
▪ Operation with either north or south pole  
▪ Configurable unipolar or omnipolar magnetic sensing  
▪ Complementary, push-pull outputs  
▪ Chopper stabilized  
omnipolar magnetic actuation. It features operation at low  
supply currents and voltages, making it ideal for battery-  
operated electronics. The low operating supply voltage,  
1.65 to 3.5V, anduniqueclockingalgorithmassistinreducing  
the average operating power consumption. For example, the  
power requirement is less than 15 μW with a 2.75 V supply.  
▫ Superior temperature stability  
▫ Extremely low switchpoint drift  
▫ Insensitive to physical stress  
Unlike more traditional Hall effect switches, theA1171 allows  
the user to configure how the device is magnetically actuated.  
Under default conditions the device activates output switching  
witheitheranorthorsouthpolaritymagneticfieldofsufficient  
strength. The magnetic actuation can be set via an external  
selection pin to operate in a unipolar mode, switching only on  
a north or south polarity but not both. Furthermore, the output  
of theA1171 can be configured to switch either off or on in the  
absence of any significant magnetic field. Lastly, the A1171  
has two push-pull output structures.  
▪ Solid state reliability  
▪ Small size  
Package: 6 pin DFN/MLP (suffix EW)

requirements,allowstheA1171toeasilyreplacereedswitches,
