All features of the ADM1062/ADM1063/ADM1064/ADM1065/
ADM1066/ADM1067/ADM1166 are programmable through an
SMBus interface. The devices also contain nonvolatile memory
(EEPROM) so that the configuration of these features can be
stored on-chip and downloaded on each power-up.

The ADM1062/ADM1063/ADM1064/ADM1065/ADM1066/
ADM1067/ADM1166 family of fully programmable supply
sequencers and supervisors can be used as complete supply
management solutions in systems using multiple voltage
supplies. Such applications include line cards in telecommunications infrastructure equipment (central office, base stations)
and blade cards in servers.
