UH8103 Datasheet

HALL EFFECT MICRO SWITCH 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 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.
 
 
FEATURES
 
*Micropower Operation
*2.5V to 5.5V Battery Operation
*Offset Canceling Technology
*Independent of North or South Pole Magnet
*Superior Temperature Stability
*Extremely Low Switch-Point Drift
