General Description：TMR7401 series leakage current sensor based on magnetic induction principle, incorporates our tunneling magnetoresistive (TMR) sensor with high sensitivity and high SNR. With the build-in conditioning circuits for offset voltage, temperature and non-linearity compensation, it provides accurate measurement of DC, AC and pulse current. TMR7401 provides excellent primary to secondary galvanic isolation, low power consumption and compact size design.

Features and Benefits：（1）Open loop current sensor;（2）Low power consumption;（3）High accuracy;（4）Single power supply;（5）Low linearity error;（6）Low offset drift over temperature .

Applications：（1）Leakage current measurement;（2）Single phase or three phase nominal current measurement;（3）Telecommunication power supply;（4）Residual current measurement in DC sources.
