Hall Effect Micro Switch IC

www.DataSheet4U.com APX9131 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 APX9131 integrated circuit is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. 2.5 volt to 3.5 volt operation and a unique clocking scheme reduce the average operating power requirements. Either a north or south pole of sufficient flux will turn the output on; in the absence of a magnetic field, the output is off. The polarity independence and minimal power requirement allow this device to be easily replaced reed switch for superior for signal conditioning. Advanced CMOS processing is used to take adv antage of low-voltage and low-power requirements, SOT-23 and TO-92 packages provide an 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). It is design with open drain configuration and connecting a pull up resistor from VOUT to VDD is necessary. It cannot be floating.
