Rprog
value is a resistance used to program a charging current in a battery charging circuit such as the one in this design that uses a TP4056 chip. The TP4056 is a standalone linear Li-Ion battery charger which allows for programmable charging current.Rprog
value according to the equation specified in the TP4056 datasheet:PROG
pin and Ground.Rprog
is set to 1.2k Ohms, indicating a designed output current of 900mA. This means that the battery will be charged at 900mA until the charge is complete, at which point the charging current will significantly decrease.
