According to the circuit diagram, it will be connected to
VBUS(USB 5V) ----> D4 ----> 5Vpin ----> 3.7V Lipo.
Isn’t it overcharged even if VBUS (USB 5V) is directly connected to the 3.7V Lipo battery?
edit:
According to the USB standard, the power supply voltage range is up to 5.25V.
The voltage drop of diode D4 is Typ 480 mV in the data sheet.
The 3.7V Lipo, which is generally considered to be charged at 4.4V, is charged at 4.77V. Is this okay?
