QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 685

750mA LINEAR BATTERY CHARGER

LTC4059

DESCRIPTION

Demonstration circuit 685 is single cell Li-ion linear

charger in a DFN 2x2. Charge rates as high as

900mA can be achieved due to the LTC4059’s internal

die temperature control loop that prevents excessive

PCB heating under worst-case conditions. The user is

provided with two jumpers. The enable jumper turns

the charger on or off, and the Li/CC jumper selects

between a Li-ion charge mode or a current source.

The Li-ion charge mode is a constant current, con-

OPERATING PRINCIPLES

Demonstration circuit 685 is a simple battery

charger. The demo features the LTC4059 charger IC

and can be configured via a jumper a CC/CV charger

or as a current source. This charger implements a

constant die temperature, constant current, and con-

stant voltage charge scheme. Charge termination is

left to the user via the En(bar) pin. In the event that

full charge current would result in excessive dissipa-

tion a die temperature control loop backs off the

charge current to maintain a reasonable PC board

temperature. The peak charge current is set at

750mA. The voltage at the PROG pin indicates

charge rate. Full current is indicated by 1.21V on the

Prog pin and 10% current will be about 120mV. The

charge current information present at the prog pin

can be used by an external controller to determine

when to terminate charging

QUICK START PROCEDURE

Demonstration circuit 685 is easy to set up to evalu-

ate the performance of the LTC4059. Refer to Figure 1

for proper measurement equipment setup and follow

the procedure below:

Use the jumper provided to select the desired

With power off, connect the input power supply to

Vin and GND.

Connect the demo board to the battery simulator

as shown in Fig. 1.

Set the battery simulator voltage to zero, slowly

charge mode either constant current (for Ni) or

constant current/constant voltage (for Li).

raise the input voltage. When the supply voltage

exceeds 3.8V the charger should activate.
