Backup Battery Charger
The backup battery charger operates as a programmable voltage limited current source with a selectable output
resistor. It is enabled by setting BBCMode in the Backup Battery Charger register to a value other than ‘00’b and offers
the following features:
Backup battery presence detection
Selectable output resistor (R BBCOUT ) to reduce the current at higher voltages
Programmable charge current I BBC
programmable maximum charging voltage V BBC
Reverse current protection turns off backup battery charger automatically if V SUPPLY <V VBACK ; as soon as V SUPPLY
exceeds V VBACK charging is started again automatically
Charging is stopped automatically as soon as the backup battery is fully charged; if the voltage on pin VBACK
drops charging is started again automatically
In case the main supply voltage V SUPPLY is larger than V VBACK charging of the backup battery is possible in state
“Off” as well; the device will check V VBACK every minute to determine if charging is required.
