Hello

I'm using this device in our product..

I have a question about power sequence.

Is it possible to start up LMP8646 in the next power sequence?

Please refer to attached file.

Does this power sequence break the LMP8646?

Thank you

Hello Keisuke,

Yes, this power supply sequence is OK. The LMP8646 is designed to handle large input common-mode voltages independently of its supply voltage. Therefore the input voltage can turn on before the power supply.
