Rev. A.1 - Mar., 2009 6 www.anpec.com.tw 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 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 is below the release point BRPS (or increases above BRPN), 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 difference in the magnetic operated and released point is the hysteresis (Bhys) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external mechanical bouncing vibration and electrical noise.

A.1 - Mar., 2009 7 www.anpec.com.tw APX9132A Application Information It is strongly recommended that an external bypass capacitor can be connected (is close to the Hall sensor) between the supply and the 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. Pole-independent The pole-independent sensing technique allows for operation with either a north or a south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole in presence. Awake & Sleep Internal awake & sleep timing block circuit activates the sensor for 180 µs and deactivates it for the remainder of the period (60 ms). A short “awake” time allows for stabilization prior to the sensor sampling and data latching on the falling edge of the timing pulse. While in sleep cycle, the output is latched in its previous state. Chopper Stabilized Technique The chopper stabilized technique cancels the mismatching of the hall element, the amplifier offset voltage and temperature sensitive drift by the dynamic offset cancellation and switched capacitor technique. This technique produces devices has an extremely stable Hall output voltage, therefore, the magnetic switch points are stable. Copyright ANPEC Electronics Corp. Rev.
