The IPS2550 is an AEC-Q100 Grade 0 automotive-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 IPS2550 can be used for high-speed motor commutation up to 600krpm electrical in the most challenging automotive functional safety-critical applications.

Stray field immunity, lower weight and smaller size, and a substantial BOM optimization make the IPS2550 the key element of the Resolver 4.0, a disruptive solution.
