Preliminary
HALL EFFECT MICRO SWITCH
IC
BiCMOS IC
„ DESCRIPTION
The UH8103 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 B_OPS(or less than B_OPN) the output turns on (output is
low). When the magnetic field is below the release point B_RPS , the
output turns off (output is high). It is designed with open drain
configuration and connecting a pull up resistor from Output to VDD is
necessary.
