Description
The A1171 integrated circuit is an ultrasensitive, Hall effect
switch with latched digital outputs and either unipolar or
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 3.5 V, and unique clocking algorithm assist in reducing
the average operating power consumption. For example, the
power requirement is less than 15 μW with a 2.75 V supply.
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
with either a north or south polarity magnetic field of sufficient
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 the A1171 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.
This polarity-independence, as well as the minimal power
requirements, allows theA1171 to easily replace reed switches,
