Functional Description
The output of the MMS105H switches low (turns on) when a
magnetic field applied along the sensing axis of the TMR
sensor exceeds the operate point threshold, B
OP
. When the
magnetic field is reduced below the release point, B
RP
, the
device output goes high (turns off). The difference between
operate and release points, B
OP
-B
RP
= B
H
, is defined as the
hysteresis of the device.
It is strongly recommended that an external bypass capacitor
of at least 0.1 μ F be connected between the supply and
ground connections and in close proximity to the MMS105H
to reduce noise and improve switching accuracy.
