Product Number: ADuM4136
Hi,
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.
Regards,
Kazu
