CMOS, OMNI-POLAR, LOW POWER HALL SENSOR

DESCRIPTION

UTC UH8118 is a low-power integrated Hall switch designed to

sense the applied magnetic flux density and give a digital output,

which indicates the present condition of the magnitude sensed.

It mainly designed for battery-powered system and hand-held

equipment, such as cellular flip-phones and PDA’s, in which power

consumption is one major concern.

There are CMOS output types and two ranks of magnetic

characters for user to choose.

FEATURES

* Omni-polar magnetic type

* 2.2V to 5.5V battery operation

* Offset Canceling Technology
