TYPICAL APPLICATION
The LTC ? 4000 is a high voltage, high performance controller
that converts many externally compensated DC/DC power
supplies into full-featured battery chargers.
Features of the LTC4000’s battery charger include: accurate
(±0.25%) programmable float voltage, selectable timer or
current termination, temperature qualified charging using
an NTC thermistor, automatic recharge, C/10 trickle charge
for deeply discharged cells, bad battery detection and
status indicator outputs. The battery charger also includes
precision current sensing that allows lower sense voltages
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.
