Infineon Technologies, a supplier of automotive semiconductor solutions, recently announced a new family of automotive sensors in its XENSIV ™ TLE4971 portfolio. 50 A, 75 A, and 120 A.
The TLE4971 is the most advanced sensing technology available and is ideally suited for automotive use cases, including on-board chargers (OBCs), high-voltage auxiliary drivers and charging applications. In addition, the current sensor is well suited for industrial applications, including DC chargers for electric vehicles, industrial drives, servo drives and photovoltaic inverters.
The Infineon XENSIV TLE4971 sensor provides accurate magnetic current sensing based on proprietary temperature and stress compensation without negative core effects due to hysteresis or saturation effects. Due to the differential sensing principle, there is also no need for de-cores or shielding to prevent stray fields. In addition, these sensors are well suited for applications using wide-bandgap solutions such as gallium nitride (GaN) and silicon carbide (SiC). The integrated EEPROM allows the user to customize the sensor's overcurrent detection (OCD) values and deburring filters for different use cases.
The sensor's small PG-TISON-8-5 package also provides a very compact design for a variety of applications. With a minimum insertion resistance of 220 µΩ and an inductance of less than 1 n, system losses are reduced, resulting in higher efficiency and accuracy. In addition, the package allows for high dynamic range, high inrush current, and market-leading thermal performance. These devices are fully compliant with AEC-Q100 Level 1 for automotive applications up to 125 °C and offer increased output accuracy. To support industrial applications, all sensor versions are available in standard and UL listed versions.
