HALL EFFECT MICRO

SWITCH IC



DESCRIPTION

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

(output is low). When the magnetic field is below the release point
