APX9132
Function Description
Operation
The output of APX9132 switches low (turn-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 (turn-on). In absence of
flux density below the release point B (or increased
RPS
above B ), the APX9132 output switches high (turns
RPN
off). After turn-off, the output is capable of sourcing up to
1mA and the output voltage is high (turn-off). The dif-
ference in the magnetic operated and released point is
the hysteresis (B_hys) of the device. This built-in hyster-
esis allows clean switching of the output even in the pres-
ence of external mechanical bouncing vibration and elec-
trical noise.
