Inductive Position Sensors

Offering significant advantages over existing Hall effect and other magnetic sensors, our sensor interface ICs measure linear, angular/rotation, proximity and/or displacement in electromechanical systems found in a variety of automotive, industrial, aerospace and commercial applications. They are excellent solutions for high-reliability and safety-critical automotive position sensor applications, such as automobile throttle body, transmission gear sensing, electronic power steering and accelerator pedals. These unique magnetic field sensors give accurate position measurements, are immune to stray magnetic fields and don’t require an external magnetic device.

Induction Position Sensors Offer:

  • Key features for improving measurement accuracy in critical applications:
    • Very low temperature drift
    • Ratio metric measurement
    • Dynamic signal compensation
  • Superior noise immunity in harsh environments:
    • Active rejection of stray magnetic fields
    • Common mode rejection for both internal and external noise sources
  • Reduced system costs:
    • No external magnet required
    • Directly interfaces with Electronic Control Unit (ECU)/host
    • Embedded microcontroller for programmable digital filtering and signal processing
  • 12 bits of resolution for any output option including:
    • Analog, PWM, SENT and PSI5
    • Sine and Cosine outputs for high-speed motor rotor position sensing
  • AEC-Q100 Grade 1 (-45 to +125°C) and Grade 0 (-45 to +150°C) certified and ISO 26262 compliant solutions
