Can I charge a LiPo battery while ATmega328P is in sleep mode without an additional charge IC?

Other Hardware General Electronics

I am using an ATmega328P and want to eliminate a hardware power switch by putting the microcontroller into sleep mode instead of fully shutting it down.

For charging, I plan to use a charging cable with integrated charge management. My LiPo battery has a built-in BMS (Battery Management System), so it already includes protection circuits for overcharge, over-discharge, and short circuits.

I plan to charge the battery directly via the charging cable, without any additional charge IC on my PCB.

My Questions:

  1. Can I safely charge the LiPo battery while the ATmega328P is in sleep mode?
  2. Can I completely eliminate an additional charge IC on my PCB, relying only on the charging cable’s built-in charge management and the BMS of the battery?

I want to ensure that the system remains safe and reliable while keeping the circuit as
simple as possible.

The excessive use of bold font is pointless and distracting.

Please post a link to the product page or data sheet for this

Most LiPo chargers cannot properly or safely charge a battery that is connected to a load.

Nice cable. Give us some details...

That depends on what you want to happen and what charging system you are using. Post a schematic or if all commercial parts a block diagram with links to technical information on the parts.

Here is an example LIPO which I would like to use: 480mah_-_lp802036ju_1s1p_2_wire_50mm.pdf

here an example charging cable: (as you can see, there are already built-in protections)

The information needed is not there and rather then cause you to damage your equipment I will not comment. However I will suggest you contact those manufacturers and see if it is doable.

thanks for your comments.
In the mean time I have researched in web: Safety charging only possible through charger IC. (best practice)
