QUICK START GUIDE FOR DEMONSTRATION CIRCUIT DC1104A MULTI CELL LI-ION BATTERY CHARGER BOARD 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 output voltage is programmed by jumpers to support 1, 2, 3 and 4-Cell Li-ion batteries with a cell voltage 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 charger, a popular smart battery connector is provided that can be used for data-logging with the OPTIONAL DC1223A-B Demoboard 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 associated software is to monitor a smart battery for demonstration 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 swapout. See schematic. Design files for this circuit board are available. Call the LTC factory. Table 1. Performance Summary PARAMETER Maximum Input Voltage CONDITIONS / NOTES Limited by Input Capacitor Volt Ratings.

Connect the input power source to VIN terminals 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 hardwire connections. 5. Turn on the input power supply. 6. Optionally use the provided DC1223A-B demonstration software to configure and communicate with the DC1104A.
