ISOW7841: Available max VISO capacitor

Part Number: ISOW7841

Hi Champs,

 Can you provide available maximum capacitor connected to Viso rail?

In the datasheet 47uF is recommended, several hundred uF is required for specific use case.

 Best regards,

Nobuo Fujihara

    Hi Nobuo,

    I understand that you are asking about the capacitance between VISO and GND2.
    We have tested our part with a few hundred uF and have not observed any issues. There shouldn't be any problems with your use case.
    Let me know if you have any more concerns regarding this specific use case.

    Regards,
