1, when input voltage (When the AC adapter or USB power supply is removed lp28056s chip circuit diagram , the TP4056 automatically enters a low current state lp28056s chip circuit diagram , reducing the battery leakage current to less than 2uA. The TP4056 can also be placed in shutdown mode when powered lp28056s chip circuit diagram to reduce the supply current to 55uA. TP4056lp28056s chip circuit diagramIts lp28056s chip circuit diagram features include battery temperature detection, undervoltage latching, automatic recharging, and two LED status pins to indicate charging and ending.
2, the figure above is the finished lithium battery charging board composed of TP4056. Its use is very simple, as long as the input end is connected to the 5V voltage output of the mobile phone charger, the BAT+ end and BAT- end on the circuit board are connected to the positive and negative terminals of the lithium battery. The charge termination voltage of this charging board is 2V.
