Data sheet
MicroPower Hall-Effect Switch
General Description
SDC8312 is a micropower 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.
The typical power consumption is below 10 uW
at 2.7V, so the micropower design is especially
suitable for battery-operated systems such as
cellular phones or laptop computers, in which
power consumption is one major concern.
The magnetic switching points are precise and
insensitive to process and temperature
variations.
For SDC8312, the output will be at the “high”
level when no magnetic field is applied.
