The LTC4013 is a high voltage battery charger that is well suited for charging a wide range of lead-acid batteries including both vented and sealed types. It supports bulk, float, absorption and equalization charging. The LTC4013 also supports termination options for Li-Ion/Polymer and LiFePO₄ batteries.

Charging is performed with a high efficiency synchronous buck (step-down) converter that uses external N-channel MOSFETs. Switching frequency is resistor programmable or can be synchronized to an external clock. Charge current is programmed with an external sense resistor.

The LTC4013 also includes maximum power point tracking input-voltage regulation for limited power sources such as solar panels. Other features include user-programmable absorption and equalization times, temperature-compensated charge voltage and an external N-channel MOSFET isolation control circuit.

Product Details

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

The DC2374A 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. It also can be configured to operate down to 5V. 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 jumper-selectable, set by two tri-state mode pins and the TIMER pin.
