A33023: Stray Field Immune, High-Speed, Hall-Effect Angle Sensor IC for Electrified Vehicle Applications

Allegro LE 14 Package Image


Top Features


The A33023 is a stray field immune, 360° angle sensor IC that provides high-resolution angular position information based on magnetic sensing technology. It is a system-on-chip (SoC) architecture that includes angle sensing, digital signal processing, and various output options: SPI, PWM, motor commutation (U,V,W), and encoder outputs (A, B, I). Integrated in the device is on-chip EEPROM technology capable of supporting a high number of read/write cycles for flexible end-of-line programming of calibration parameters. The low latency of the A33023 makes it ideal for automotive applications requiring fast 0° to 360° angle measurements.

  • Stray-field immune
  • Designed to meet ASIL D requirements when used in conjunction with appropriate system-level control
  • High accuracy and resolution
  • Low latency
  • Wide operating voltage (3.7 V to 18 V)
