In absence of lization prior to the sensor sampling and data latching on the falling edge of the timing pulse. While in sleep cycle, flux density below the release point BRPS (or increased above BRPN), the APX9132G output switches high (turns the output is latched in its previous state. off). After turn-off, the output is capable of sourcing up to 1mA and the output voltage is high (turn-off).

This built-in hyster- ing of the hall element, the amplifier offset voltage and temperature sensitive drift by the dynamic offset cancel- esis allows clean switching of the output even in the presence of external mechanical bouncing vibration and elec- lation and switched capacitor technique.

A.1 - Oct., 2009 7 www.anpec.com.tw APX9132G Application Information It is strongly recommended that an external bypass capacitor be connected (is close to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies. Copyright ANPEC Electronics Corp. Rev.
