A19360 - High-Resolution GMR Wheel Speed/Distance Sensor

📥 Download Datasheet

General Description

The A19360 is a magnetic sensor integrated circuit (IC) that uses giant magnetoresistance (GMR) technology to encode the speed and direction of rotating ring magnets.

Innovative algorithms generate additional events per magnetic cycle while staying robust to air-gap variation, to provide high-resolution rotational data that can be used for accurate distance measurement.

The A19360 is compatible with standard ring magnets used in automotive braking systems, and Allegro programs each IC according to the characteristics of the magnet used.

Overview

A19360 High-Resolution GMR Wheel Speed and Distance Sensor IC.

Key Features

  • High-resolution measurement for enhanced ADAS accuracy, such as for automated parking.
  • GMR technology delivers high magnetic sensitivity for large air gaps and low-jitter switching.
  • SolidSpeed Digital Architecture provides robust, adaptive performance for high output accuracy and fullpitch vibration immunity.
  • Integrated solution includes the IC and a protection capacitor in a single overmolded package.
  • ISO 26262 ASIL B(D) with integrated diagnostics.
