Hello,
TPS23750 and TPS23770 has different UVLO rising voltage as follows.
TPS23750 39.3V typical (Standard)
TPS23770 35.1V typical(Legacy)
UVLO rising voltage of TPS23753/TPS23756/TPS23757(released later) is 35V and same with Legacy of TPS23770.
I think PD input voltage minimum specification of IEEE802.3af is 36V so UVLO rising should be 35V(not 39.3V).
Q1:
Please explain the case “TPS23750 UVLO 39.3V typical” is required.
Q2:
About” TPS23770 UVLO 35.1V typical(Legacy)”, Legacy has a meaning of “old” but TPS23753/TPS23756/TPS23757(released later) has same UVLO voltage with Legacy.
Please explain why 39.3V is Standard and 35.1V is Legacy.
Beast Regards.
