Introduction

AI Translation

The LTC4015 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 lead-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 supported 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.
