Automotive current sensors in TDSO package

Infineon Technologies XENSIV™ - TLE4973 for automotive product image

TLE4973 is an accurate current sensor family for automotive use, particularly in electric vehicles. The sensors work at 5 V with an analog output as well as over current detection output. One digital control and diagnostic interface provides temperature readout, safety status readout, read / write programming access to internal EEPROM. The measurement range of up to +/-34 mT allows to sense currents up to 2 kA without the negative effects, e.g. hysteresis and saturation.

 

Key features

  • Highly accurate coreless magnetic current sensor
  • 5 V supply voltage
