Operation
The output of APX9132 switches low (turns on) when
in presence of strong flux density facing the marked
side of package exceeds the operate point B
OPS
(or is
less than B
OPN
). After turn-on, the output is capable of
sinking up to 1mA and the output voltage is low (turns
on). In absence of flux density below the release point
B
RPS
(or increased above B
RPN
), the APX9132 output
switches high (turns off). After turn-off, the output is
capable of sourcing up to 1mA and the output voltage
is high (turns off). The difference in the magnetic oper-
ated and released point is the hysteresis (B
hys
) of the
device. This built-in hysteresis allows clean switching
of the output even in the presence of external me-
chanical bouncing vibration and electrical noise.
Function Description
Awake & Sleep
Internal awake & sleep timing block circuit activates
the sensor for 180 us and deactivates it for the re-
mainder of the period (60 ms). A short “awake” time
allows for stabilization prior to the sensor sampling
and data latching on the falling edge of the timing pulse.
While in sleep cycle the output is latched in its previ-
ous state.
Chopper Stabilized Technique
The chopper stabilized technique cancels the mis-
matching of the hall element, the amplifier offset volt-
age and temperature sensitive drift by the dynamic
offset cancellation and switched capacitor technique.
This technique produces devices have an extremely
stable Hall output voltage, therefore the magnetic
switch points are stable.
Application Information
It is strongly recommended that an external bypass
capacitor be connected (in close to the Hall sensor)
between the supply and ground of the device to re-
duce both external noise and noise generated by the
chopper-stabilization technique. This is especially true
due to the relatively high impedance of battery supplies.
Pole-independent
The pole-independent sensing technique allows for
operation with either a north 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 in presence.
