LTC4009-2
DESCRIPTION
Demonstration circuit DC1104A is a single-battery
charge controller with featuring the LTC4009-2.
The input voltage is 13.5 to 20V. The charger out-
put voltage is programmed by jumpers to support
1, 2, 3 and 4-Cell Li-ion batteries with a cell vol-
tage of 4.2V/Cell. The maximum charge current is
2A. The demo board is initially configured for
12.6V Li-ion batteries. The board will automatically
charge a battery as soon as input power is applied
with a battery connected prior to power up. Status
LEDs are provided for CHG, ACP, C/10, and ICL
although this charger is not a smart battery charg-
er, a popular smart battery connector is provided
that can be used for data-logging with the
OPTIONAL DC1223A-B Demoboard and soft-
ware. To be clear, you DO NOT need a smart bat-
tery to use this board. The optional DC1223A-B
SMBus-to-USB port adapter and associated soft-
ware is to monitor a smart battery for demonstra-
tion purposes only. Contact your LT representative
for ordering a DC1223A-B.
This Demoboard is capable of supporting the
LTC4009 and LTC4009-1 with a simple IC swap-
out. See schematic.
Design files for this circuit board are available.
Call the LTC factory.

1. Connect the input power source to VIN termin-
als J1 or VIN and GND using a power supply
capable of handling 2.5A of current within a
13.5 to 20V range. The input supply voltage
MUST be greater than the full voltage value of
the battery to allow a full charge to take place.
2. Connect the load to VOUT and GND terminals.
3. Configure the jumpers for your specific battery.
4. Plug in the battery. Industry-standard 5 Pin
AMP Smart Battery connector is provided as
well as generic soldering Test Points for hard-
wire connections.
5. Turn on the input power supply.
6. Optionally use the provided DC1223A-B dem-
onstration software to configure and communi-
cate with the DC1104A.
