ADP5065: Compatible with USB Power Energy Fast Battery Charging Management Solution

ADI's ADP5065 is a FET device with embedded DC voltage charging output and battery terminals. Battery isolation is achieved through FETs. When the system drive power comes from a used battery or no battery, the system will immediately switch to USB power mode. The ADP5065 has an input voltage range of 4V to 5.5V and a maximum input voltage of up to 20V. There is no need to worry about the USB bus being disconnected or the peak during the connection. The ADP5065 charger is compatible with USB 2.0, USB 3.0 and USB battery charging specifications 1.1. The ADP5065 is available in a very small package in a 20-pin WLCSP package (0.5mm pitch).
