Inductive Position Sensor with Single-Coil Sensing Element Featuring SENT, SPI, UART, ABI, PWM, Step/Dir, and UVW Interfaces

The RAA2P3500 is a magnet-free, inductive position sensor IC designed for absolute rotary, linear, or arc position sensing in automotive applications. It operates on the principle of eddy currents, detecting the position of a simple metallic target moving above a set of coils, consisting of one transmitter coil and two receiver coils.

This architecture enables precise and accurate position measurements, making it ideal for high-speed automotive systems such as HV traction motor, brake booster, belt starter, and electric power steering applications. Its robust, magnet-free design ensures reliable performance in harsh automotive environments, offering a durable and cost-effective alternative to traditional magnetic sensing technologies.
