ADuM4136 Regarding the startup sequence

Category: Hardware
Product Number: ADuM4136


I have a question about the order of power and signal input at startup of the ADuM4136.

- On the primary side, power supply: VDD1 is turned on first, and then the signals (Vi+, Vi-, RESET, Fault, Ready) are input.

- On the secondary side, power supply: VDD2 and VSS2 are applied first, and then the signal DESAT is input.

- There is no rule as to whether the primary or secondary side should be turned on first.

- The power supply must be turned on before the signal is input.

Is my understanding correct? If there is a mistake, please correct me.
