The board typically accepts 5 volts as input (on the SOL contacts), which can come from a standard power supply, a miniature solar panel, or even a computer's USB connector. From the SOL contacts, the supply voltage reaches the input (VIN) of the MCP73831T charge controller, which accepts input voltages in the range of 3.75÷6 volts and supplies the output current needed to charge lithium-ion or lithium-polymer (Li-Po) cells, delivering 170 milliamps to our battery. The battery (to be connected to the +/- BAT contacts) can have a theoretically unlimited capacity, because at most it charges in a very long time, however, considering the charging current of 170mA, a 550 mAh cell will charge in just over 3 hours, an 1,100 mAh cell will require almost 7 hours, a 5.5 Ah cell will need 33 hours, and so on. In the breakout board, the integrated circuit operates in the standard configuration, with the light-emitting diode LD1 powered (via resistor R1, connected to the PROG contact, which limits its current) by the STAT output. This output goes to a low logic level during charging and remains high at the end of charging. It switches to high impedance (open) when the MCP73831T is in shutdown mode or when no battery is currently connected to the VBAT output. This last output (pin 1) is the line to which the battery is connected. Dimensions (mm): 21x21x6. Set charging current: 170mA. #electronics #batteries #tutorial
