GENERAL DESCRIPTION

The ACT3704 is a complete linear charging solution

for single cell Lithium Ion and Lithium Polymer bat-

teries. It incorporates an internal 12V power MOS-

FET for Constant-Current, Constant-Voltage control

(CC/CV).

The battery regulation voltage accuracy is ± 0.5%

and can be set to either 4.1V or 4.2V. The charge

current is programmed with an external resistor to a

maximum of 1A to minimize total charge time.

The reverse leakage current from the battery is less

than 1µA if the input adaptor is disconnected or if

there is a reverse battery connection. The ACT3704

is available in thermally-enhanced SOP-8/EP, and

TDFN33-8 packages to accommodate high charge

current operation and minimize total charging time.
