MicroPower Hall-Effect Switch
Datasheet
SDC212
General Description
Features
SDC212 is a micropower integrated Hall switch designed
Tto sense the applied magnetic flux density and give a
digital output, which indicates the present condition of
Nthe magnitude sensed. The typical power consumption
Eis below 10 uW at 2.7V, so the micropower design is
especially suitable for battery-operated systems such as
Mcellular phones or laptop computers, in which power
Uconsumption is one major concern.
CThe magnetic switching points are precise and
insensitive to process and temperature variations.
OFor SDC212, the output will be at the “high” level when
Dno magnetic field is applied.
Micropower consumption
2.4V~4.5V power supply
Chopper amplifier based design: insensitive to
noise and offset caused by process variations,
operating temperature and mechanical stress
Switching for both polar of a magnet(Omnipolar)
Digital output
CMOS process
Package: SOT-23-3, TO-92S
Applications
Folding, sliding, rotary screen mobile phone
Notebook computer, digital camera
