General Description

The A1333 is a 360° angle sensor IC that provides contactless high-resolution angular position data based on magnetic circular vertical Hall (CVH) technology.

It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and motor commutation (UVW) or encoder outputs (A, B, I).

It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters.

Overview

A1333 2 - Precision, High Speed, Hall-Effect Angle Sensor IC with Integrated Diagnostics for Safety-Critical.

Key Features

  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement.
  • Capable of sensing magnet rotational speeds targeting 12-bit effective resolution with 900 G field.
  • Circular vertical Hall (CVH) technology provides a single-channel sensor system supporting operation across a wide range of air gaps.
  • Developed in accordance with ISO 26262 requirements for hardware product development for use in safetycritical.
