DESCRIPTION

The ATS16351 is a True Power-On State (TPOS) camshaft

sensor incorporating a back-biasing magnet, advanced fully

synchronous digital IC, and EMC protection circuit all in a

single sensing solution.

The ATS16351 incorporates a GMR bridge 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 sensor 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 Auto-TPOS feature of the ATS16351 enables the sensor

IC to learn the installation air gap inside of the engine and to

autonomously reprogram into memory the optimal threshold

for power-on accuracy.

A number of factory-programmable options allow for

performance optimization to meet specific application

requirements.

The ATS16351PSM is available in a 3-pin package (SM) that

is lead (Pb) free, with 100% NiPdAu plating
