A1333 Overview
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 mutation (UVW) or encoder outputs (A, B, I).
A1333 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
- Developed in accordance with ISO 26262 requirements for hardware product development for use in safetycritical
