Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
However, no responsibility is assumed for its use. Linear Technology Corporation makes no represen-

The LTC
1730 is a complete pulse charger for 1-cell
lithium-ion batteries. During pulse charging, the internal
MOSFET switch is either fully on or off, virtually eliminat-
ing heat generation in the charger.
As the battery becomes charged and approaches the
programmed voltage, the internal MOSFET begins to
pulse on and off until the programmable timer expires. The
end-of-charge condition is indicated at the CHRG pin when
the average charge current falls to
C
/10. Removing the
input voltage puts the LTC1730 into a sleep mode, drop-
ping the battery current drain to less than 1
μ
A (maximum).
An external sense resistor limits the maximum charge
current as a safety precaution against a user connecting a
wall adapter with the incorrect or no current limit. The
internal MOSFET prevents reverse battery current from
flowing if the input voltage is shorted to ground, eliminat-
ing the need for a blocking diode.
The LTC1730-4 is available in the 16-pin SSOP package
and the LTC1730-4.2 is available in the 8-pin SO package.
