Maxim公司的MAX14748是USB Type-C充电器,集成了充电检测器,升压/降压转换器和带智能功率选择器的锂电池充电器,支持USB Type-C 1.1尺度的UFP/DRP功能,JEITA 充电掩护,±15kV ESD掩护,主要用在数字图像(DSC,DVC),无线扬声器和手持条码扫描器.本文先容了MAX14748主要优势和特点,框架图,系统框架图以及评估板MAX14748 EVK主要特点.电路图,质料清单和PCB设计原理图. 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 ℃ to +85℃ extended temperature range MAX14748主要优势和特点: MAX14748应用: Digital Imaging (DSC, DVC) 评估板MAX14748 EVK The MAX14748 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX14748 USB Type-C charger.
