A17301 Datasheet Three-Wire Zero-Speed Differential Peak-Detecting Sensor

Manufacturer: Allegro MicroSystems

General Description

The A17301 integrates a single IC and EMC components into a small SIP package, providing a robust and cost-effective solution for digital ring-magnet sensing or ferromagnetic target sensing when coupled with a back-biasing magnet.

The device can be used in two-wheeled vehicle applications where a wide variety of target shapes and sizes are used.

The integrated circuit incorporates dual Hall-effect elements with 2.2 mm spacing and signal processing that switches in response to differential magnetic signals created by ringmagnet poles.

Overview

A17301 Three-Wire Zero-Speed Differential Peak-Detecting Sensor IC with Continuous.

Key Features

  • Immune to common external magnetic disturbance.
  • Operates down to 20 Gpk-pk differential input field for large air gaps or small back-biasing fields.
  • Running mode recalibration after start-up vibration ensures immunity to possible target anomalies.
  • Accurate duty cycle on output signal throughout operating temperature range and air gaps.
  • Integrated capacitors for EMC performance.
