General Description

The AAS33051 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 to calculate the angular position data, and multiple output formats: serial protocol (SPI), pulse-width modulation (PWM), and either 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 programming of calibration parameters.

Overview

AAS33051 Precision Angle Sensor IC with Incremental and Motor Commutation Outputs and On-Chip.

Key Features

  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement.
  • Capable of sensing magnet rotational speeds targeting 12.5-bit effective resolution with 300 G field; higher effective resolution possible at higher field strengths.
  • 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 impac.
