TLI4971A075T5E0001XUMA1

TLI4971A075T5E0001XUMA1 is a high-precision coreless current sensor for industrial applications. It is a high-precision miniature coreless magnetic current sensor for AC and DC measurements with an analog interface and two fast over-current detection outputs. 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. 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. Typical applications are electrical drives and general-purpose inverters, PV inverters, chargers, current monitoring, overload and over-current detection.
