Cache-Memory Battery-Backup Management IC
Reapplication of Power
This is essentially the reverse process from the power-
loss sequence. Power is applied to the RAID card; the

power supply remains off. The cache-backup supply in
the DS2731 automatically switches from the battery
source to the 3.3V bus when the 3.3V bus goes above
2.93V. The system then disables ENS and enables the
cache’s power MOSFET, connecting the cache to the
main cache power supply. Enough bulk storage capac-
itance must be available at the cache to hold up during
this switchover time. The memory is now ready to exit
from autorefresh mode (IDD6 for DDR2 memory) and
resume full operation.
