Infineon Technologies XENSIV Magnetic Current Sensors
Infineon Technologies TLI4971 XENSIV Magnetic Current Sensors use coreless sensing technology to deliver high accuracy and high linearity AC and DC current measurements in high voltage applications, such as electric drives and photovoltaic inverters.
The TLI4971 is capable of measuring current up to 120A, and the magnetic sensing offers high galvanic isolation. Measurements are output as an analog voltage, and the IC also has fast overcurrent detection with programmable thresholds to protect output stages.
The measurements are internally compensated for temperature and stress to achieve 2% accuracy, and a single-point in-system calibration can be used for greater accuracy. The current rail is designed to suppress stray fields and has ultra-low resistance to minimize power loss.
The TLI4971 has a compact QFN-type package for use in high power density designs.
