CMOS Omnipolar High Sensitivity Micropower Hall Switch

V3.10 Nov 1, 2013

Typical Application Circuit

SEC's pole-independent sensing technique allows for

operation with either a north pole or south pole mag-

net 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.
