Part Number: TIDA-01513

Hi Sir,

May I know how do we get leakage current result in table 9 as below? (in TIDA-01513 design guide)

Thank you.

    Hi Sir,

    In the test, we will use two resistors R_ISOP and R_ISON (as shown in the following picture )to simulate the insulation resistance.

    From that, we can simply calculate the expected output voltage ISO_POS and ISO_NEG, with this two voltage, we can also calculate the leakage current. 

    For the measured result, we get ISO_POS and ISO_NEG directly, then we use ISO_POS and ISO_NEG to calculate the measured leakage current.

    Thanks,

    Anna
