DESCRIPTION
High Efficiency,
Multi-Chemistry
Battery Charger
The LTC4009 is a constant-current/constant-voltage battery
charger controller. It uses a synchronous quasi-constant
frequency PWM control architecture that will not generate
audible noise with ceramic bulk capacitors. Charge cur-
rent is set by the combination of external sense, input and
programming resistors. With no built-in termination, the
LTC4009 family charges a wide range of batteries under
external control.
TheLTC4009featuresafullyadjustableoutputvoltage,while
the LTC4009-1 and LTC4009-2 can be pin-programmed for
lithium-ion/polymer battery packs of 1-, 2-, 3- or 4-series
cells. The LTC4009-1 provides output voltage of 4.1V/cell,
and the LTC4009-2 is a 4.2V/cell version.
The device includes AC adapter input current limiting which
maximizes the charge rate for a fixed input power level. An
external sense resistor programs the input current limit, and
the ICL status pin indicates when the battery charge current
is being reduced as a result of AC adapter current limiting.
The CHRG status pin is active during all charging modes,
including special indication for low charge current.
