APX9131
Hall Effect Micro Switch IC
Features
General Description
The APX9131 integrated circuit is an ultra-sensitive,
pole independent Hall-effect switch with a latched
digital output. 2.5volt to3.5volt operationandaunique
clocking scheme reduce the averageoperating power
requirements. Either a northor south pole of sufficient
flux will turn the output on; in the absenceof amagnetic
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-92packagesprovidean
optimized package for most applications.
