I'm building a circuit incorporating 2 li-ion charge circuits based on the TP4056.
The TP4056 has a charge pin to illuminate an LED when the cell is being charged and a standby pin to illuminate an LED when charging is complete.
As I'm essentially merging the two circuits into one board I only want one set of LED indicators so I need some logic on the pins of each chip, I believe this can be done with transistors.
The method will be slightly different for each because the charge LED should only turn off after current has stopped flowing through both charge pins in each circuit and the standby LED should only turn on once current is flowing through both standby pins.
Any help appreciated
