TLI4971A025T5UE0001XUMA1

TLI4971A025T5UE0001XUMA1 is a high-precision miniature coreless magnetic current sensor for AC and DC measurements with the analog interface and two fast over-current detection outputs. Infineon's well-established and robust monolithic hall technology enables accurate and highly linear measurement of currents with a full scale up to ±120A. All negative effects (saturation, hysteresis) commonly known from open loop sensors using flux concentration techniques are avoided. The sensor is equipped with an internal self-diagnostic feature. Typical applications are electrical drives and general-purpose inverters. The differential measurement principle allows great stray field suppression for operation in harsh environments. Two separate interface pins (OCD) provide a fast output signal in case a current exceeds a pre-set threshold. The sensor is shipped as a fully calibrated product without requiring any customer end-of-line calibration.
