High‑precision magnetic position sensor with configurable 12‑bit or 14‑bit PSI5 output (PSI5 v1.3/2.3) for accurate full 360° angle measurement. Hall‑based analog front-end ensures reliable operation and strong stray‑field immunity. Supports programmable sub‑range for optimized resolution. Requires simple 2‑pole magnet. Robust automotive design with up to 16.5 V operation, +20 V overvoltage and −18 V reverse polarity protection. The AS5173F is based on AS5173 but features lower idle current consumption.

Features

  • 12-bit resolution @90° minimum arc
  • Low output noise, low inherent INL
  • Magnetic stray field immunity
  • Functional safety, diagnostics
  • AEC-Q100 Grade 1 qualified
  • System cost reduction: PCB less + reduced BOM

Benefits

  • Resolve small angular excursion with high accuracy
  • Accurate angle measurement
  • Higher durability and lower system costs (no shield needed)
  • Enabler for safety critical applications
  • Suitable for automotive applications
  • SIP Package (System-in-Package)
