Description

Demonstration circuit 2374A is a multi-chemistry batterycharger with maximum power point tracking (MPPT)featuring the LTC®4013. The LTC4013 has 2 stage CC/CVcharge cycles, 3 stage and 4 stage lead acid and Li-Ionbattery algorithms.The DC2374A is set up to operate from a 21.5V to 35Vsupply or from a solar panel and charges a six cell leadacid battery at 5A. There are optional input and outputcapacitors plus large inductor pads and parallel top andbottom FET pads to allow high power charging.The LTC4013 is a 60V controller which makes it suitablefor large battery stacks with up to a 60V supply or solarpanel input. An MPPT burst mode feature allows the deviceto efficiently charge in low light levels. Since the LTC4013is a controller, the power train can be sized from 1A to over 10A of charge current. The LTC4013 also has an NTCtemperature compensated float voltage to help increasethe battery life.The operating frequency, charge voltage, low battery (LB)voltage setting and timing are configurable with externalresistors and a capacitor. The different charging algorithmsare set by two tri-state mode pins and the TIMER pin asshown in Table 1.Refer to the LTC4013 data sheet for more details on theelectrical and timing specifications.
