The MAX14748 USB battery charger integrates a charger detector, boost/buck converter, and Li+ battery charger with smart power selector to provide fast and safe charging of 2s Li+ battery packs.

The MAX14748 provides support for devices functioning as a UFP/DRP per the USB Type-C 1.1 standard, while also providing detection of legacy USB Battery Charging Specification, Revision 1.2 (BC1.2) compliant chargers in addition to other nonstandard chargers. The programmable Automatic Input Current Limiting (AICL) feature ensures that maximum safe current is drawn from the charging adapter.

The Li+ charger includes an automatic Smart Power Selector^™ to simultaneously charge the battery and provide power to the system load. The Smart Power Selector function will supplement the system power with the battery if power from the charging adapter is insufficient. The Li+ charger features JEITA thermal monitoring and charger voltage/current reduction or charger disable.

The MAX14748 is available in a 54-bump, 0.4mm pitch, 3.97mm x 2.77mm x 0.64mm wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
