XENSIV™ TLE4972 Magnetic Sensor

Infineon’s magnetic sensor offers reliable current measurement over its lifetime without recalibration

Image of Infineon XENSIVE™ TLE4972 Magnetic SensorInfineon Technologies' XENSIV TLE4972 is a high-precision, miniature, coreless magnetic sensor for AC and DC measurement and is qualified according to AEC-Q100. The sensor provides an analog output proportional to the magnetic field measured. Additionally, two digital outputs for indication of overcurrent events are available. Infineon's well-established and robust monolithic hall technology enables accurate and highly linear measurement of the magnetic field caused by the current. The measurement range of up to ±31 mT allows it to sense currents up to 2 kA without the negative effects (e.g. hysteresis and saturation) known from core-based sensors.

Features
  • Protection against overcurrent, also for fast switching technologies
  • Very low power dissipation
  • Support for safety-critical applications
  • Reliable current measurement over its lifetime without recalibration
  • Programmable gain settings to adapt the sensor to the system needs
  • Two independent overcurrent detection pins
  • Programmable gain and overcurrent thresholds
  • ISO 26262 compliant development for safety requirements up to ASIL B
  • Very low sensitivity error overtemperature and lifetime
  • Separate path for very fast overcurrent detection (typ. response time <0.7 µs)
  • Programmable sensitivity to optimize sensing performance
Applications
  • Traction inverters (high-voltage and 48 V)
  • Auxiliary drives
  • Battery main switches
  • Current monitoring
  • Overload and overcurrent monitoring
  • Automotive powertrain
