Description

Top Features

Packaging

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

Typical Applications
