About

Fault detection solutions maximize performance and protect passengers

Thermal runaway detection

  • Ambient sensing with automotive-grade XENSIV™ solutions (e. g., pressure, smoke)
  • Cell over-temperature and undervoltage monitoring with accurate cell monitoring ICs
  • Cost-efficient Electrochemical Impedance Spectroscopy (EIS) solutions for early and deep-in-cell damage detection

Battery disconnection monitoring

  • Relay state (e.g., open or close)
  • Relay armature position detection

Isolation monitoring

Loss of high-voltage domain isolation detection

Overcurrent detection (OCD)

Reliable and ultra-fast overcurrent detection using automotive-grade XENSIV™ solutions

Best-in-class robustness with compact design and lowest PPM rates

Infineon's highly integrated products significantly decrease the footprint and help customers reduce costs by minimizing PCB size. Besides, Infineon's zero-defect Mindset is reflected in the lowest PPM rates in the market and significantly reduces vehicle downtime and returns.
