QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 498 3 AND 4 CELL LI-ION BATTERY CHARGER BOARD WITH BUILT IN CHARGE TERMINATION

Overview

TopologyBuck Converter
Input voltage15-20 V
Output 112.6 V / 3 A

Description

Demonstration circuit 498 is a single battery standalone battery charge controller with built in charge termination featuring the LTC®4007. The input voltage is 13 to 20V. The charger output voltage is programmedby 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 isinitially configured for 12.6V Li-ion batteries. The board will automatically charge a battery to termination as soon as input power is applied with a battery connected prior to power up. Status LEDs are provided 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 associated software to monitor a smart battery are fordemonstration purposes only. Contact your LT representative for ordering a DC1223A-B.
