This system is a power bank for low power electronics such as watches, earbuds and charging cases. The system operates as a standalone and requires no programming of an MCU, and it accepts inputs from a USB wire or a wireless docking station. The DA9070 power management IC operating in standalone mode charges the battery when an input is present or manages the rest of the system while discharging the battery. An additional P9415 wireless charging receiver operating in transmit mode allows for a 5W power transfer to charge or power light electronics.
