CMOS High Sensitivity Micropower Hall Latch
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) between
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.
