ATS16301: Auto-TPOS Camshaft Sensor with Integrated EMC Protection 

SL Package


Top Features


The ATS16301 is a True Power-On State camshaft sensor incorporating a non-rare-earth back-biasing magnet, advanced fully synchronous digital IC, and an EMC protection circuit all in a single sensing solution.

The ATS16301 incorporates a single element Hall IC with an optimized custom magnet that switches in response to magnetic signals induced by a ferromagnetic target. The IC contains a sophisticated digital circuit designed to match the temperature behavior of the IC with the integrated magnet. Signal processing is used to provide zero-speed performance independent of air gap and is designed for the typical operating conditions found in automotive camshaft sensing applications. The resulting output of the device is a digital representation of the ferromagnetic target profile. A number of factory-programmable options allow for performance optimization to meet specific application requirements.

  • SL package provides a fully integrated solution with a non-rare-earth back-biasing magnet and EMC protection circuit
  • True target state recognition at device power-on (TPOS) with automatic TPOS self-programming capability
  • EEPROM programming for performance optimization, temperature compensation, and production traceability
  • Fully synchronous digital logic with Scan Path and IDDQ testing for high quality and reliability
  • Chopper stabilization reduces offset drift
  • Absolute zero-speed performance
