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. 2.5 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-v oltage and low-power

requirements, SOT-23 and TO-92 packages provide an

optimized package for most applications.
