General Description：

The MAX8600A single-input linear battery charger safely charges single-cell Li+ batteries. Charging is optimized for Li+ cells using a control algorithm thatincludes low-battery precharging, voltage and currentlimited fast-charging, and top-off charging, while continuously monitoring the battery for overvoltage,over/under temperature, and charging time. Chargertimeout protection is programmable, and the status isindicated by three open-drain outputs.The MAX8600A linear charger optimizes charging timeby adjusting the charge rate to accommodate the thermal characteristics of a given application. There is noneed to reduce the maximum charge current to accommodate worst-case charger power dissipation.The MAX8600A is a variation of the MAX8600 withimproved dropout and other spec changes. SeeMaxim’s website for an outline of MAX8600/MAX8600Adifferences.The MAX8600A is available in a 3mm x 3mm powerenhanced TDFN package.
