Hi,
in the datasheet of the TPS65950, the recommended operating maximum
ratings of "BKBAT" are min 1,8V and max 3,3V.
If a user insert the backup-battery wrong, the voltage at BKBAT is -3,0V.
Will this negative voltage destroy the IC or is a protection circuit inside?
(In my schematic a 1k-resistor is in series to the battery)
Regards,
Daniel
