APX9132A
Function Description
Operation
The output of APX9132A 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 is below the release point B (or increases
RPS
above B_RPN), the APX9132A output switches high (turns
off). After turn-off, the output is capable of sourcing up to
1mA and the output voltage is high (turn-off). The differ-
ence in the magnetic operated and released point is the
hysteresis (B ) of the device. This built-in hysteresis al-
hys
lows clean switching of the output even in the presence
of external mechanical bouncing vibration and electrical
noise.
