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.
