Hi Kai,

It is generally 10% tolerance so 82 can work with up to 18V input.

Thanks,
Rahul

Hi Kai,

Yes, you can modify this setting by changing the "Under-voltage Protection Usage, PP_HV" in the "System Configuration (0x28)" register.

This setting can be changed from 5-50%, but be aware that increasing the percentage will not help in all the cases as other connected end might trat lower voltage as under voltage and stop working.

Thanks,
Rahul
