Overview

The NCV77320 is an inductive position sensor interface that, in combination with a PCB, forms a system to measure 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. The NCV77320 contains 3 interfaces: A single ended analog output, a SENT interface with fast and slow channel and a SPI channel for direct interconnection to a micro controller. The analog output is proportionally ratio metric with the supply voltage. The NCV77320 has several fault detection circuitries. When a fault is detected, fault flags are set and available for readout.
