The LTC®4015 is a complete synchronous buck controller/charger with pin selectable, chemistry specific charging and termination algorithms. The LTC4015 can charge Li-Ion/Polymer, LiFePO4, or leadacid batteries. Battery charge voltage is pin selectable and I2C adjustable. Input current limit and charge current can be accurately programmed with sense resistors and can be individually adjusted via the I2C serial port. A digital telemetry system monitors all system power parameters.
