TMR7401
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 pensation, it provides accurate measurement of DC, AC and pulse current. TMR7401 provides excellent primary to secondary galvanic isolation, low power consumption and pact size design.
