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.
