General Description

The APX9131 integrated circuit is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. 2.5 volt to3.5 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 advantage of low-voltage and low-power requirements, SOT-23andTO-92 packagesprovide an optimized package for most applications.
