A16311数据手册Allegro中文资料规格书

描述 Description

The A16311PUCA is a True Power-On State camshaft sensor incorporating an advanced fully synchronous digital IC and EMC protection circuit all in a single sensing solution.

The A16311 is a single element Hall-effect sensor IC which, when paired with a back-biasing magnetic circuit, 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 back-biasing magnet (either SmCo or NdFeB). Advanced signal processing is used to provide zero-speed performance independent of installation 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 A16311 is highly programmable with many options to allow for performance optimization to meet specific application requirements.

The A16311 is provided in a 3-pin SIP package (UCA) that is lead (Pb) free, with 100% matte tin leadframe plating.

For applications that require an integrated back-bias magnet for directly measuring camshafts, please see the ATS16301.
