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 V_DD is necessary.
