Function Description
Operation output APX9132 switches (turns when pres ence strong flux density facing marked side package exceeds operate point BOPS less than BOPN). After turn-on, output capable sinking output voltage (turns on). absence flux density below release point BRPS increased above BRPN), APX9132 output switc high (turns off). After turn-off, output capable sourcing output voltage high (turns off). difference magnetic operated released point hysteresis (Bhys) device. This built-in hysteresis allows clean switching output even pres ence ernal mechanical bouncing vibration electrical noise. Pole-independent pole-independent sens technique allows operat with either north south pole magnet orientat ion, enhancing manufacturabilit device. stat e-of-the-art technology provides same output polarity either pole presence. Awake Sleep Internal awake sleep timing block circuit activates sensor deac tivates remainder period ms). short "awake" time allows stabilizat prior sensor sampling data latching falling edge timing pulse. While sleep cycle output latched previous state. Chopper Stabilized Technique chopper stabiliz technique cancels misOUTPUT OUTPUT VOLTAGE BOPN BOPS
