A1333 - Allegro

A1333 Hall-Effect Angle Sensor

The A1333 is a 360° angle sensor IC that provides contactless high-resolution angular position information 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 tec.

Features

• Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement □ Capable of sensing magnet rotational speeds targeting 12b 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 applications □ Single die version designed to meet ASIL B requirements when integrated and used in conjunction with the appropriate system-level c.
