description
The TPS3606-33 supervisory circuit monitors and
controls the processor activity. In case of power-
fail or brownout conditions, the backup-battery
switchover function of the TPS3606-33 allows a
low-power processor and its peripherals to run
from the installed backup battery without
asserting a reset beforehand.
