Functional Description
The AAT3689 is a highly integrated single cell lithi-
um-ion/polymer battery charger IC designed to
operate with USB port and AC adapter inputs,
while requiring a minimum number of external
components. The AAT3689 precisely regulates
battery charge voltage and current for 4.2V lithium-
ion/polymer battery cells.
The adapter charge input constant current level
may be programmed up to 1.0A for rapid charging
applications. In the absence of a high current
adapter input source, the AAT3689 may be pow-
ered from a USB port V
BUS
supply. The USB con-
stant charge current can be externally pro-
grammed for maximum constant current charge
levels up to 500mA. The USB charge function is
automatically disabled when an adapter input
power source greater than 4.5V is present.
Status monitor output pins are provided to indicate
the battery charge status by directly driving two
external LEDs.
Battery temperature and charge state are fully mon-
itored for fault conditions. In the event of an over-
voltage or over-temperature failure, the device will
automatically shut down, thus protecting the charg-
ing device, control system, and the battery under
charge. In addition to internal charge controller ther-
mal protection, the AAT3689 also provides a tem-
perature sense feedback function (TS pin) from the
battery to shut down the device in the event the bat-
tery exceeds its own thermal limit during charging.
Charging Operation
Regardless of which charge input function is select-
ed (i.e., either the adapter input or USB input), the
AAT3689 has four basic modes for the battery
charge cycle: pre-conditioning/trickle charge; con-
stant current/fast charge; constant voltage; and end
of charge (see Figure 1).
