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 be connected (in close proximity to the Hall sensor) be-

tween the supply and ground of the device to reduce both external noise and noise generated by the chop-

per-stabilization technique. This is especially true due to the relatively high impedance of battery supplies.
