Product Details

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.

Applications

  • Battery Backup for Lighting, UPS Systems, Security Cameras, Computer Control Panels
  • Portable Medical Equipment
  • Solar-Powered Systems
  • Industrial Battery Charging
