Other Parts Discussed in Thread: BQ25100,
Dear sir
I have a system that should be working on USB VBUS with data transmission on the data lines and i want to add battery to the system that can fire up the system before blogging it to USB VBUS with the following characteristics:
* a button that connect the battery to the system when needed (not ON all the time)
* charging circuit that charge the battery when blogging it to USB
* switching mechanism to connect the system to VBUS once the USB is connected
* time out signal that disconnect the battery when it works for certain time with no VBUS detected (I will handle the time out flag)
could you provide me with solutions you provide for similar design?
best regards
Mahmoud Abed
