The LTC®4000 is a high voltage controller and power manager which, when paired with a DC/DC converter, becomes a full-featured battery charger solution. The LTC4000 is capable of driving virtually any topology, including buck, boost, buck-boost, SEPIC and flyback converters. Its intelligent PowerPath manager provides power to the system load when input power is available, enabling instant-on operation even with a deeply discharged battery. A full-featured controller, the LTC4000 can charge a variety of battery types including lithium, nickel and lead acid-based chemistries. Highly accurate charge current and float voltage, as well as onboard termination, ensure safe and accurate charging.
