Typical Application Circuit

SEC's pole-independent sensing technique allows for operation

with either a north pole or south pole magnet orientation,

enhancing the manufacturability of the device. The

state-of-the-art technology provides the same output polarity

for either pole face.

It is strongly recommended that an external bypass capacitor be

connected (in close proximity to the Hall sensor) between the

supply and ground of the device to reduce both external noise

and noise generated by the chopper-stabilization technique.

This is especially true due to the relatively high impedance of

battery supplies.
