ATS679: Self-Calibrating TPOS Camshaft Speed Sensor

Description

The ATS679LSL is a True Power-On State camshaft sensor incorporating a non-rare-earth back-biasing magnet, advanced fully synchronous digital IC, and EMC protection circuit all in a single sensing solution.

The ATS679 incorporates a single element Hall IC with an optimized custom magnetic circuit 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.

The ATS679 is provided in a 3-pin SIP package (SL) that is lead (Pb) free, with 100% matte-tin leadframe plating
