Inductive Position Sensor Interface
NCV77320
Introduction The NCV77320 is a single−chip inductive position sensor interface
that, in combination with a PCB, forms a system that measures angular or linear positions accurately.
The operating principle of the inductive sensor is based on mutual inductance. The chip contains an excitation source, which generates an AC magnetic field through a primary coil on the PCB. The field mutually couples to the rotor. The rotor on its turn induces voltages in secondary coils. These voltages, measured by the chip, depend on the rotor position and give a measure for the position.
