HALL EFFECT MICRO SWITCH IC
DESCRIPTION
The UH8104 is a low power, pole independent Hall-effect
switch with a latched digital output driver. It can work in 2.5V
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). It is
designed with open drain configuration and connecting to a pull up
resistor from Output to VDD is necessary.
FEATURES
* Micro power operation
* 2.5V to 5.5V battery operation
