TPS62840: Anti reverse to avoid abnormal

Part Number: TPS62840

Dear Team,

The current expected use environment is: power supply using two CR2032 series power supply,

In actual use, there will be abnormal situations where the battery is reversed connect.


After the battery is reversely installed, a negative voltage (about -3v) will be poured in.

questions.
1. Does this IC have any protection to against negative voltage to prevent damage?
Or do we need to add anti-reverse power supply to protect the IC?
2. Are there any recommended countermeasures for anti-reverse connection circuits for reference? Thank you.

Regards,
