The TP4056 serves as the charge control chip, it drops the voltage linearly from 5V 1A down to 4,2V 1A. The DWO1-A serves a BMS for the lithium-ion battery. The 8205LA is a double mosfet which gate signal is controlled by the DW01-A in case of any dangerous event the lithium battery will be disconnected.
