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.
