Hall Effect Micro Switch IC
The UH8105 is a low power, pole independent Hall-effect switch
with a latched digital output driver. It can work in 2.5 volt supply.
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.
When a magnetic field enters the hall element and exceeds the
operate point BOPS(or less than BOPN) the output turns on (output is
low). When the magnetic field is below the release point BRPS (or
above BRPN), the output turns off (output is high).
*2.5V to 5.5V battery operation
*Offset Canceling Technology
*Independent of North or South Pole Magnet,
*Superior temperature stability
*Extremely Low Switch-Point Drift
