DescripTion
High Voltage High Current
Controller for Battery Charging
and Power Management
TheLTC4000isahighvoltage,highperformancecontroller
that converts many externally compensated DC/DC power
supplies into full-featured battery chargers.
FeaturesoftheLTC4000’sbatterychargerinclude:accurate
(±0.25%) programmable float voltage, selectable timer or
current termination, temperature qualified charging using
anNTCthermistor,automaticrecharge,C/10tricklecharge
for deeply discharged cells, bad battery detection and
status indicator outputs. The battery charger also includes
precisioncurrentsensingthatallowslowersensevoltages
for high current applications.
The LTC4000 supports intelligent PowerPath control. An
external PFET provides low loss reverse current protec-
tion. Another external PFET provides low loss charging
or discharging of the battery. This second PFET also
facilitates an instant-on feature that provides immediate
downstream system power even when connected to a
heavily discharged or short faulted battery.
The LTC4000 is available in a low profile 28-lead 4mm ×
5mm QFN and SSOP packages.
