Description
The MAX8600/MAX8601 single-/dual-input linear battery chargers safely charge single-cell Li+ batteries. The charging rate is optimized to accommodate the thermal characteristics of a given application. There is no need to reduce the maximum charge current or worst-case charger power dissipation. Charging is optimized for Li+ cells using a control algorithm that includes low-battery precharging, voltage and current-limited fast-charging, and top-off charging, while continuously monitoring the battery for overvoltage, over/undertemperature, and charging time. The charger timeout protection is programmable. The charger status is indicated by three open-drain outputs.
The MAX8601 automatically selects between either a USB or AC adapter input source. The AC adapter charge current is programmable, while USB charge current is set not to exceed either 100mA or 500mA, depending on the USEL input. The MAX8600 is a single-input charger with no USB source input.
The MAX8600/MAX8601 are available in a 3mm x 3mm power-enhanced TDFN package.
