TPS65381 NRES pin is supposed to be directly connected to Hercules nPORRST pin.
According to datasheet, NRES pin is internally pull-up with ~4.5kOhm.
nPORRST pin is internally pull-down with 100uA.
So the signal state is around 3V due to balancing of these pulls.
Hercules VIH is max. 2V, so there should be no issue, but my customer wants to confirm why these pins are designed so.
Thanks and regards,
