QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 672
LI-ION CHARGER IN DFN 3X3
LTC4058-4.2
DESCRIPTION
Demonstration circuit 672 is a single cell Li-Ion
charger in a DFN3x3. Charge rates as high as 800mA
can be achieved due to the LTC
®
4058 package’s ex-
cellent thermal performance and internal die tempera-
ture control loop that prevents excessive PCB heating
under worst-case conditions. The user is provided
with a control jumper to enable the charger. An en-
able terminal is also provided to simplify wiring the
demo board into a system. The user is also provided
with 3 status outputs. The PROG terminal outputs a
voltage proportional to the charge current. The
ACPR
terminal is pulled low whenever sufficient input volt-

CHARGE
terminal is pulled low every time charge current is
supplied to the output. The status of the
ACPR

CHARGE
outputs of the LTC4058 are also indicated
visually by two LED’s.

OPERATING PRINCIPLES
Demo 672 is a simple single cell Li-Ion charger. The
circuit features the LTC4058-4.2 charger IC. This
charger implements a constant die temperature, con-
stant current, and constant voltage charge scheme.
Charge termination occurs when the charge rate falls
to beneath 10% of the programmed charge current.
A topping charge will be applied if the cell voltage
falls to 4.05V to insure long-term charge mainte-
nance. Deeply discharged cells are conditioned with
a low C/10 trickle current until the cell voltage
reaches 2.9V whereupon full charge current is ap-
plied. In the event that full charge current would re-
sult in excessive IC temperature, a die temperature
control loop backs off the charge current to maintain
a reasonable PC board temperature. Two LED’s are
provided for status indication. A charge LED is pro-
vided that illuminates every time the charger is charg-
ing the battery, and an AC power LED is provided to
indicate that the part is out of under-voltage lockout.
The peak charge current is 800mA.
