LOW POWER HALL EFFECT

SWITCH

DESCRIPTION

UH8100 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 is down to 15uW at 2.75V supply.

For UH8100, the output will be high when no magnetic field is

applied and be low when the applied magnetic flux density is stronger

than the switching threshold. The difference between UH8100A and

UH8100B is that UH8100A consumes less power than UH8100B in the

Hall sensor operation.
