Inductive Position Sensor for High-Speed Motor Commutation

The IPS2200 is an industrial-qualified, inductive position sensor IC capable of providing the absolute rotor position as sine and cosine. This IC uses the physical principle of Eddy currents to detect the position of a simple metallic target moving above a set of coils, consisting of one transmitter and two receivers. The output interface can be configured as single-ended, for higher system cost effectiveness or differential to better reject common mode disturbers. The IPS2200 can be used for high-speed motor commutation up to 250krpm electrical, in industrial, medical, robotic, and consumer applications.

Stray filed immunity, lower weight, smaller size, and a substantial BOM optimization make the IPS2200 the key element of the Resolver 4.0, a disruptive solution.
