A33002 Overview
The A33002 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-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing to calculate the angular position data, and selectable output protocols (SPI, SENT, or PWM).
A33002 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 with air-gap independence
- On-chip 32-segment linearization to improve angle accuracy
- Reduces the impact of magnet-to-sensor misalignment
- Reduces the impact of imperfect magnetization of target magnet
- Developed in accordance with ISO 26262 requirements for hardware product development for use in safetycritical
