Product Details

Demonstration circuit 2374B is a multi-chemistry battery charger with maximum power point tracking (MPPT) featuring the LTC4013. The LTC4013 has 2 stage CC/CV charge cycles, 3 stage and 4 stage lead acid and Li-Ion battery algorithms.

The DC2374B is set up to operate from a 21.5V to 35V supply or from a solar panel and charges a six cell lead acid battery at 5A. There are optional input and output capacitors plus large inductor pads and parallel top and bottom FET pads to allow high power charging.

The operating frequency, charge voltage, low battery (LB) voltage setting and timing are configurable with external resistors and a capacitor. The different charging algorithms are set by two tri-state mode pins and the TIMER pin.
