IPS2550 Inductive Position Sensors

The IPS2550 from Renesas 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 600,000 rpm 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.
