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.
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.
