Packaging

The A17802 IC is an advanced inductive position sensor designed to measure the rotational angle of a metallic target and output the information over a differential sine and cosine analog interface. The IC features digital processing that optimizes the inductive front-end and applies compensations that maximize system-level angle accuracy.

The A17802 provides a high-speed absolute-angle sensor that is suitable for advanced synchronous motor control, including automotive electric motor systems.

The A17802 was developed in accordance with ISO 26262 as a hardware safety element out of context. with ASIL C capability for use in automotive safety-related systems.

  • Measures angle with <0.5°el accuracy at speeds up to 250k eRPM
  • Automatic TX and RX optimization at each power-up
  • Harmonic compensation reduces error by up to 3x
  • Synchronization compensation perfects commutation timing for efficient motor control
  • Programmable zero angle enables arbitrary target alignment
  • Programmable via SPI or Manchester Protocol
  • Developed in accordance with ISO 26262:2018 ASIL C(D) (pending assessment)
