How Chips Use On-Chip Magnetic Field Sensors for Contactless Current Sensing

Episode 111 of The Hardware Podcast explores how semiconductor designers are embedding tiny magnetic field sensors directly into chips to measure electrical current without physical contact. Lucas and Luna dive into the Hall effect principle, a specific implementation from Infineon's XENSIV product line, and a real-world application in electric vehicle battery management systems where on-chip magnetometers replace bulky shunt resistors. They discuss sensitivity challenges at the micron scale, noise handling in automotive environments, and how this technology enables safer, more efficient power electronics. The episode closes with a look at future integration with wide-bandgap semiconductors like silicon carbide. #HallEffect #ContactlessCurrentSensing #Infineon #XENSIV #ElectricVehicles #BatteryManagement #SiliconCarbide #PowerElectronics #Semiconductors #MagneticFieldSensors #OnChipSensors #CurrentMeasurement #AutomotiveElectronics #WideBandgap #Technology #HardwarePodcast #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
