General Description
The APX9131, integrated circuit, is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. A 2.5 volt to 3.5 volt operation and an 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-23-3, TSOT-23-3, and TO-92M3 packages provided an optimized package for most applications.
