IQS7225A ProxFusion® Inductive Sensor

Azoteq's sensor fusion device is for inductive sensing applications requiring relative rotational inductive sensing

Image of Azoteq IQS7225A ProxFusion® Inductive SensorAzoteq's IQS7225A ProxFusion IC is a sensor fusion device mainly aimed at inductive sensing applications that require relative rotational inductive sensing, multiple inductive buttons, or both. The device also has capacitive sensing capabilities that can be used to complement the inductive sensing applications, e.g., a capacitive wake-up channel. The sensor is fully I²C compatible, and on-chip calculations enable the IC to respond effectively even in its lowest power modes.

Features
  • Highly flexible ProxFusion device
  • 9 (QFN) external sensor pad connections
  • Configure up to 6 channels using the external connections
  • External inductive sensor options:
    • Up to 6x self-capacitive buttons
    • Up to 6x mutual-capacitive buttons
    • Up to 6x inductive buttons
  • Built-in basic functions:
    • Gray-coded relative rotational encoder
    • Selectable channel reference
      • LTA as reference
      • Select channel to use as reference
      • Fixed value as reference
Applications
  • Waterproof inductive dial/counter applications
  • Waterproof inductive buttons
  • Integrated control panel (dial + buttons)
  • White goods user interface
  • Wearables
  • Smart home controllers
