Hi Hasegawa-san,

This is an English forum, so please restate your question in English.

This app note discusses various reverse battery protection circuits: www.ti.com/.../slva139.pdf

I'm sorry.

PMOS is included in Power Stage
Is this effective for reverse input?

Thank you.

Thanks for clarifying your question.

No, the device (and most all devices in the market) do not support a reversed/backwards battery on the input. This would violate the (negative) abs max rating on the Vin pin, for example.
