Battery Backup System ManagerThe LTC4110 is a complete single chip, high efciency,
yback battery charge and discharge manager with auto-
matic switchover between the input supply and the backup
battery or super capacitor. The IC provides four modes of
operation: battery backup, battery charge, battery calibra-
tion and shutdown. Battery backup and battery charge are
Automatic standalone modes, while the optional calibration
mode requires a CPU host to communicate over an SMBus
During calibration the yback charger is used in reverse
to discharge the battery with a programmable constant
current into the system load eliminating heat generation.
Three status outputs CAN be individually recon gured over
the SMBus to become GPIOs. User programmable over-
discharge protection is provided. The SHDN pin isolates
the battery to support shipping the product with a charged
battery installed. By Linear Technology Corporation
