Hall Effect Micro Switch IC

www.DataSheet4U.com APX9132 Hall Effect Micro Switch IC Features • • • • • Micro Power Operation for Battery Applications Chopper Stabilized Amplifier Independent of North or South Pole Magnet, Easy for Manufacture Small Size Package Lead Free Available (RoHS Compliant) General Description The APX9132 integrated circ uit is an ultra-sensit ive, pole independent Hall-effect switch with a latched digital output . A 2.5 volt t o 3.5 volt operation and a unique clocking scheme reduce the average operating power requirements, Either a north or sout h pole of sufficient flux will turn the output on; in the absence of a magnetic field, t he out put is off. The polarit y independence and minimal power requirement allow t his devic e t o be easily replac ed reed swit c h for s uperior for s ignal c ondit ioning. A dvanc ed CMOS proc es s ing is used to take advantage of low-voltage and low-power requirements, SOT-23 package provided a optimized package for most applications.

When the magnetic field is below the release point BRPS (or above BRPN ), the output turns off (output is high).
