Infineon Technologies XENSIV™ - TLE4971

Current sensor with integrated current rail for automotive and industrial. High-precision miniature coreless magnetic sensor for AC and DC measurement. The sensor provides an analog output proportional to the current 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 newly developed TISON-8-6 power package enables optical inspection in the assembly line, fulfilling automotive requirements.
