Product Overview

The LTC4110EUHF#PBF is a Battery Charge And Discharge Manager with automatic switchover between the input supply and the backup battery or super capacitor. This high efficiency fly-back complete single chip 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 a SMBus. During calibration the fly back 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 over discharge protection is provided.
  • Charge and discharge battery with voltages above and below the input supply voltage
  • No heat battery calibration discharge using system load
  • Automatic battery backup with input supply removal using PowerPath™ control
  • Adjustable battery float voltage
  • ±0.5% Precision charge voltage
  • Optional temperature qualified charging
