LOW POWER HALL EFFECT

SWITCH



DESCRIPTION

UH8102 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. The typical power consumption

of UH8100 at down to 10uW in 2.7V supply.

For UH8102A, the output will be at the “Low” 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

“High” level.

For UH8102B, 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.
