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

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
