detailed description (continued)
backup-battery switchover
In case of a brownout or power failure, it may be necessary to preserve the contents of RAM. If a backup-battery
is installed at VBAT, the device automatically switches the connected RAM to backup power when VDD fails. In
order to allow the backup-battery (e.g., a 3.6-V lithium cell) to have a higher voltage than VDD, these supervisors
do not connect VBAT to VOUT when VBAT is greater than VDD. VBAT only connects to VOUT (through a 15- switch)
when VDD falls below VIT and VBAT is greater than VDD. When VDD recovers, switchover is deferred either until
VDD crosses VBAT, or until VDD rises above the reset threshold VIT. VOUT connects to VDD through a 1- (max)
PMOS switch when VDD crosses the reset threshold.
