UHE4913

DESCRIPTION 

UHE4913 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 is 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. The typical power 

consumption of UHE4913 is down to 10μW in 2.7V supply. 

The output will be at the “High” level when no magnetic field is 

applied. When the applied magnetic flux density is stronger than 

the switching threshold, the output would be at the “Low” level. 

FEATURES 

* Micropower Operation 

* 2.4V to 5.5V Battery Operation 

* Switching for both poles of magnet 

* Offset Canceling Technology 

* Superior Temperature Stability 

* Extremely Low Switch-Point Drift 

* Insensitive to Physical Stress
