The MAXREFDES1214 is a portable USB charger that uses a lithium-ion (Li+) battery to charge a USB device from a USB Standard-A connector. The battery can be charged through Micro-USB. The MAXREFDES1214 is compliant with USB Battery Charger (BC) revision 1.2 on both USB ports. It has dynamic charger detection to automatically set the maximum charge current allowed to the battery based on the source’s capability. It also features a USB adapter emulator that supports Apple® 1A charging in addition to devices that are compliant with USB BC 1.2. For added flexibility, an I2C bus provides fault monitoring and shutdown capability for the buckboost regulator.<p>Key Features<p>Battery Charger Input Current up to 1A<p>USB Standard-A Output Current up to 1.5A<p>4400mAh Li+ Battery<p>Thermal and Overcurrent Protection on the USB Standard-A Output<p>I2C Headers for Flexible Logic Levels from 1.8V to 5.0V<p>Orange LED to Indicate if the Battery Is Charging<p>No External Reverse Blocking Diode Required Between Battery and Charger
