Hi Everybody,
Is there a way to charge the battery with just connecting the battery through the 5V pin ?
Or it’s just going to discharge the battery but never charge it ?
The Seeed Studio XIAO nRF52840 uses a charger IC BQ25100
The document shows the output of the charger:
OUT
that’s for
Battery Connection. System Load may be connected.
The bq2510x has a single power output that charges
the battery. A system load can be placed in parallel
with the battery as long as the average system load
does not keep the battery from charging fully during
the 10 hour safety timer.
So, it’s probably connected to the 5V pin too.
That’s how the battery must power the Seeed Studio XIAO when it’s not charging.
That must look like this
I’m looking for the schema that will show me that information.
Any idea where I could find this ?
That must be there maybe:
So if you connect a battery to 5V pin (VIN),
and plug the USB, the battery will be charged directly by the USB 5V and not through the charger
because the USB connection will make the MOSFET non conductive
and therefore, there won’t be a connection with VBAT.
Is this correct?
That sounds like a bad idea.
Thanks.
Cheers!
