UH8103

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 BOPS(or less than BOPN) the output turns on 

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

BRPS , 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.
