DESCRIPTION
The LTC®4110 is a complete single chip, high efficiency, flyback battery charge and discharge manager with automatic switchover between the input supply and the backup battery or super capacitor.

The IC provides four modes of operation: battery backup, battery charge, battery calibration 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 flyback 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 reconfigured over the SMBus to become GPIOs. User programmable overdischarge protection is provided. The SHDN pin isolates the battery to support shipping the product with a charged battery installed. Multiple LTC4110s can be combined to form a redundant battery backup sy
