Dear all,
I am designing the battery system of my sensor device(based on cc25xx MCU 3.3V). Can anyone suggest an all-in-one power supply IC (charger+ switch+ regulator) as shown in the figure?
The system has 2 power sources: Li-Po battery and USB. When the USB is plugged in, it will charge up the battery, and at the same time, the power source switches to USB. When the USB is disconnected, the power supply switch back to the Li-Po battery.
The power supply system should also integrated a regulator: ie: always provides a regulated 3.3V (no matter which power source is used) for the MCU system. It would be nice to have fuel guage integrated into it as well.
I have google for the whole night, but can't find an IC which would do the jobs. As I think that this is very common in battery powered equipment, I beg your suggestions for a solution. Thank you!
QM.
