The AS8579 is a capacitive sensor that detects the change of capacity in different automotive applications.The capacitive sensor measures the impedance using the most reliable measurement principle. It can be used for capacitive touch & proxmity detection and fluid level measurements.

特性

  • I/Q-Signal demodulation
  • 10 independent measurements (10 SEN lines)
  • VAR+FIX_SEN function to avoid parasitics
  • Designed according functional safety standard
  • AEC-Q100 Grade 1 qualified

产品优势

  • Accurate capacitive measurement (seperation of resistive and capacitive information)
  • Higher durability and lower system costs
  • Enabler for safety critical applications
  • Suitable for automotive applications
