Description

The requirements for higher quality and performance in digital SLR cameras, DSC, and other 2S Li+ battery electronic equipment is increasing. The most important among these is battery life. The USB Type-C meets the USB 3.0 high-speed data transmission requirements. It also supports up to 20V/5A charging power. It is the best way to solve the problem of fast charging multiple batteries. Maxim Integrated’s highly integrated charger, MAX14748, is the optimal solution for both the high voltage and USB-C detector challenges. The estimation of battery power is also most relevant to the user experience. Maxim Integrated has specialized fuel gauge chips based on the ModelGauge m5 algorithm, with the lowest power consumption and estimation accuracy in the industry.
