TheLTC4015canchargeLi-Ion/Polymer,LiFePO4,orlead- acid 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. Safety timer and current termination algorithms are sup- ported for lithium chemistry batteries. The LTC4015 also includes automatic recharge, precharge (Li-Ion) and NTC thermistor protection. The LTC4015's I2C port allows user customization of charger algorithms, reading of charger status information, configuration of the maskable and programmable alerts, plus use and configuration of the Coulomb counter. Available in a 38-Lead 5mm × 7mm QFN package.
