FEATURES
APPLICATIONS
DESCRIPTION
The 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 recongured 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.
Multiple LTC4110s can be combined to form a redundant
battery backup system or increase the number of battery
packs to achieve longer backup run times.
The LTC4110 is available in a low prole (0.75mm), 38-pin
5mm × 7mm QFN package. The QFN features an exposed
metal die mount pad for optimum thermal performance.
