LTC4013IUFD#PBF

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. It 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. It 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. It is used in applications such as battery backup for lighting, UPS systems, security cameras, computer control panels, portable medical equipment, solar-powered systems, industrial battery charging.
