DEMO MANUAL DC1614A

compatible with this charger. The optional DC1223A-B

SMBus-to-RS232 Serial port adapter and associated

software can be used to monitor a smart battery for dem-

onstration purposes only. Contact your Linear Technology

representative to order a DC1223A-B.

DC1614 features an optional circuit for sealed lead acid

(SLA) batteries for constant-voltage charging with tem-

perature compensation and fast/float voltage toggling.

DC1614 also features layout for extra components and

external gate drivers for improved efficiency at higher

charge currents.

This demo board is capable of supporting the LTC4012 and

LTC4012-3 with a simple IC swap-out. See the Schematic

Diagram.

Design files for this circuit board are available at

http://www.linear.com/demo

DESCRIPTION

LTC4012

High Current High Efficiency

Multi-Chemistry Battery Charger

with PowerPath Control

Demonstration circuit 1614 features the LTC4012CUF, a

multi-chemistry single battery charger controller with

PowerPath™ control. The input supply voltage is 13.5V to

20V and is initially configured for a current limit of 10A.

The charger float voltage is programmed by jumpers to

support 1- to 4- series cells of both Li-Ion/Polymer and

Li-iron phosphate (LiFePO4) at 4.2V/cell and 3.6V/cell,

for a total of eight settings. The demo board is initially

configuredforconstant-voltagechargingofa12.6VLi-Ion/

Polymer battery and constant-current charging at 8A,

though current derating may be necessary due to certain

operating conditions.

Charging can be enabled/disabled by properly setting

the shutdown jumper. LED indicators for CHG, ICL, ACP,

and C/10 display the current state of the charger system.

Although this charger is not a smart battery charger, a

popular smart battery connector is provided that can be

used for further data-logging with the optional DC1223A-B

demo board and software. Note that a smart battery is not

required to use this board; however, smart batteries are

DEMO MANUAL DC1614A

QUICK START PROCEDURE

Demonstration circuit 1614 is easy to set up to evaluate

the performance of LTC4012. Refer to Figure 1 for proper

measurement equipment setup and follow the procedure

below.

1. With all power off, connect an input power supply

capable of more than 10A, system load, battery, and

meters as shown in Figure 1. Preset the load to 0A and

VIN to 0V, 0A current limit. 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 jumpers as shown below for normal LED-

indicated operation:

JP2 JP3 JP4 JP5

Shutdown VCC Select Internal VCC LED PWR

THM INT ON ON

3. Connect the system load to VOUT and GND terminals.

4. Connect the jumper JP1 for the specific battery to be

tested.

5. Turn the input power supply on, setting the current limit

up to 10A. Adjust the voltage to the desired value, up

to 20V.

6. Plug in the battery. An industry-standard 5-pin AMP

smart battery connector is provided for convenience.

The board will automatically charge a battery upon

insertion and detection of a thermistor. Optionally

set jumper JP2 to ON to charge a battery without a

thermistor.

7. Turn the load on and adjust as necessary. At 10A input,

the input current will limit and the ICL LED will turn

on. Note that above a certain load setting, depending

on your VIN and battery voltage, the charger will start

to decrease charge current until the system load is

consuming all of the current from the input. For 15V

input and 12.6VBAT setting this will occur at about 3.3A.

8. Optionally evaluate the SLA circuit, removing the

jumper on JP1, as well as R14. The voltage feedback

network can now be customized to match the battery

manufacturer’s specifications. The SLA circuit can be

found in the bottom left-hand corner on the top side

of the board.

9. Optionally use the provided DC1223A-B demonstra-

tion software to configure and communicate with the

DC1614A, connecting DC1223A-B as in Figure 1.

10.For improved efficiency at high charge currents, install

additional MOSFETs in Q8 and Q10 positions and/or

gate driver circuit transistors and supply capacitors

in Q7, Q9, C21, and C25. These components may be

installed on the bottom side of the board.
