Infineon's new XENSIV TLE4971 series sensors
Infineon has expanded its automotive sensor portfolio with the new XENSIV™ TLE4971 series of sensors. The 3.3V XENSIV™ TLI4971 device is housed in a TISON package with integrated rail structure and supports four preset current ranges of 25 A, 50 A, 75 A and 120 A. With its compact design and advanced environmental awareness, the TLE4971 series is suitable for a variety of automotive use cases, including on-board chargers (OBC), high-voltage auxiliary drives, and charging applications.
Based on its unique temperature and stress compensation characteristics, Infineon's XENSIV TLE4971 device enables accurate magnetic current sensing without negative effects due to hysteresis or saturation effects of the magnetic core. Due to the differential sensing structure, no magnetic core or shielding is required to make it immune to stray fields. In addition, this family of sensors is ideal for applications using wide bandgap solutions such as Gallium Nitride (GaN), Silicon Carbide (SiC), etc. The integrated EEPROM allows customers to customize the sensor's over-current detection (OCD) threshold and anti-jamming pulse filter according to different applications.
Housed in the small PG-TISON-8-5 package, this sensor family offers a highly compact design for a wide variety of applications. With a minimum insertion resistance of 220 µΩ and an inductance value of less than 1 nH, system losses are reduced and system efficiency and measurement accuracy are improved. Additionally, the package features high dynamic range, high inrush current, and class-leading thermal performance. The XENSIV TLE4971 family of devices is AEC-Q100 Grade 1 qualified for automotive applications operating up to 125°C and features improved output accuracy. To support industrial applications, all sensors in this series are available in standard and UL-listed versions.
