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 BOPS (or is less than

BOPN). 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 (Bhys) 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.
