ISO7760: Estimation for Current consumption

Part Number: ISO7760

Dear Technical Support Team,

How do I estimate for current consumption of ISO7760?

             input　　output

Case1:  3.3Ｖ ⇒ 5Ｖ 　(Vcc1 :3.3V、 Vcc2: 5V)

Case2: 5Ｖ     ⇒ 3.3Ｖ  (Vcc1 :5V、 Vcc2: 3.3V)

Datasheet shows Vcc1=Vcc2=5V or 3.3V for Current consumption.

However it doesn't have above situation.

Best Regards,

ttd

    Hi TTD,

    The isolator ISO7760 has two dice inside where each die will operate independently from each other. Since they operate from independent power supply, ICC1 & ICC2 currents are separately given in all the tables. Please see my inputs below,

    Case1: Refer ICC1 values from the table where VCC1 = VCC2 = 3.3V. Refer ICC2 values from the table with VCC1 = VCC2 = 5V.

    Case2: Refer ICC1 values from the table where VCC1 = VCC2 = 5V. Refer ICC2 values from the table with VCC1 = VCC2 = 3.3V.

    Let me know if you have any questions, thank you.
