Unique temperature and stress compensation function, enabling precise magnetic current detection
Suitable for applications adopting wide bandgap solutions such as GaN and SiC

Infineon Technologies (hereafter Infineon) introduces current sensors suitable for automotive and industrial applications.

Infineon announced today the launch of the XENSIV™ TLE4971 current sensor family, which combines advanced sensing capabilities in a compact design.

These 3.3 V products are the next generation of the TLI4971 devices and are available in a TISON package with integrated current rails and four current settings (25 A, 50 A, 75 A and 120 A).

XENSIV™ TLE4971 is suitable for automotive applications such as onboard chargers, high-voltage auxiliary drives, and charging applications, as well as industrial applications such as electric vehicle DC chargers, industrial drives, servo drives, and PV inverters.

Infineon's XENSIV TLE4971 enables precise magnetic current detection using unique temperature and stress compensation.

This product solves the problems of existing core type current sensors such as hysteresis and saturation effect, and does not require a core or shielding to avoid being affected by external stray fields by applying the differential sensing principle.

Additionally, these sensors are suitable for applications employing wide bandgap solutions such as GaN and SiC.

Integrated EEPROM allows users to customize the sensor's overcurrent detection (OCD) value and de-glitch filter depending on their use case.

The small PG-TISON-8-5 package enables compact designs for a wide range of applications.

It reduces system losses with a minimum insertion resistance of 220µΩ and an inductance of less than 1nH, thereby improving efficiency and accuracy.

Additionally, this package features high dynamic range, high surge current, advanced thermal performance, and is fully AEC-Q100 Grade 1 qualified for automotive applications up to 125°C, providing improved output accuracy.

To support industrial applications, all products are available in standard and UL certified versions.
