General 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).

Overview

A16311 Self-Calibrating Automatic-TPOS Camshaft Speed Sensor.

Key Features

  • Allegro UC package with integrated EMC components reduces need for external EMI protection.
  • 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.
  • Chopper stabilization reduces offset drift.
