CMOS, OMNI-POLAR, LOW POWER HALL SENSOR

DESCRIPTION

UH81061 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 three output types (Internal 100K pull-up resistor,
NMOS open-drain and CMOS push-pull ) and two ranks of
magnetic characters for user to choose.

FEATURES
* Omni-polar magnetic type
* 1.7V to 3.6V battery operation
* Offset Canceling Technology
* Independent of North or South Pole Magnet,
* Superior temperature stability
* Extremely Low Switch-Point Drift

APPLICATIONS
*Micro Switch
*Handheld Wireless Application Wake Up Switch
*Clamp Shell Type Application Switch
*Magnet Switch in Low Duty Cycle Applications
