Part Number: ISOW7840
Other Parts Discussed in Thread: ISO7840,

Tool/software:

Hi Expert,

This is Shenzhen FAE Evan. My customer is evaluating ISO7840, in their scenario, in integrated DCDC should transfer 3.3V to 5V. And they will also connect about 50mA external load on 5V Viso. Can you please help to confirm if it is recommended to use Viso to power the 50mA external load?

Regards,

Evan

    Hi Evan,

    Thank you for reaching out.

    IISO(OUT) refers to the output current supported on VISO pin of ISOW7840. If the device is used in 3.3V to 5V voltage configuration then the maximum output current supported (~38mA) is specified as shown the table below. Let me know if you have any other questions, thanks.
