TLI4971 XENSIV™ Magnetic Current Sensors

Infineon Technologies TLI4971 XENSIV™ Magnetic Current Sensors offer high-precision bi-directional AC and DC current measurements with an analog interface and two fast overcurrent detection outputs. The sensors support power circuitry protection, and galvanic isolation is provided due to the magnetic sensing principle. Infineon's monolithic Hall technology enables accurate and highly linear measurement of currents with a full scale up to 120A. Negative effects, like saturation and hysteresis, are commonly known from core-based sensor techniques and are not present in the Infineon open-loop, core-less sensors principle. The smart current rail design (double U-shape), combined with differential signal sensing, makes the current sensor robust against stray fields.
