Linear Technology LTC4007 Bedienungsanleitung

QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 498

3 AND 4 CELL LI-ION BATTERY CHARGER BOARD WITH BUILT IN CHARGE TERMINATION

LTC4007

DESCRIPTION

Demonstration circuit 498 is a single battery stand-

alone battery charge controller with built in charge

termination featuring the LTC®4007. The input voltage

is 13 to 20V. The charger output voltage is pro-

grammed by jumpers to support 3- and 4-Cell Li-ion

batteries with a cell voltage of 4.1V or 4.2V/Cell. The

maximum charge current is 4A. The demo board is

initially configured for 12.6V Li-ion batteries. The

board will automatically charge a battery to termina-

tion as soon as input power is applied with a battery

connected prior to power up. Status LEDs are pro-

vided for CHG, ACP, FAULT, FLAG, ICL and LOBAT.

An onboard NTC thermistor is provided. Although this

charger is not a smart battery charger, a popular

smart battery connector is provided that can be used

for data logging with the optional DC1223A-B demo

board and software. To be clear, you do NOT need a

smart battery to use this board. The optional

DC1223A-B SMBUS to USB Port Adapter and asso-

ciated software to monitor a smart battery are for

demonstration purposes only. Contact your LT repre-

sentative for ordering a DC1223A-B.

Design files for this circuit board are available. Call

the LTC factory.

Table 1. Performance Summary

PARAMETER CONDITION VALUE

Maximum Input Voltage Limited by input Capacitor Volt Ratings. 20V +/- 10 %

Recommended Minimum Input Voltage Vin > Vbat Termination voltage. 13V when using a 12.6V Li-ion battery.

Input Current Limit 3.5A

Maximum Charge Current Vin > Vbatmax > 6V 4A +/- 5%

QUICK START PROCEDURE

Demonstration circuit 498 is easy to set up to eva-

luate the performance of the LTC4007. Refer to Figure

1 for proper measurement equipment setup and fol-

low the procedure below:

NOTE: When measuring the input or output voltage

ripple, care must be taken to avoid a long ground lead

on the oscilloscope probe. Measure the input or out-

put voltage ripple by touching the probe tip directly

across the VIN or VOUT and GND terminals. See Figure

2 for proper scope probe technique.

1. Connect the input power source to DCIN termin-

als J1 or DCIN and GND using a power supply ca-

pable of handling 4A of current within an 11 to 20V

range. The input supply 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. The industry standard 5 Pin

AMP Smart Battery connector is provided as well

as generic soldering Test Points for hardwire con-

nections.

5. Turn on the input power supply.

6. Optionally use the provided DC1223A-B demon-

stration software to control and configure the

DC498A.

7. NOTE: If the board is allowed to get warm, the

onboard NTC thermistor may trip and momentarily

suspend the charge process. This can be con-

firmed by the fault LED turning on. When the board

cools down, charging will resume.
