In my application, I plan to use the BC127 and my main power supply is 3.0V (with no battery connection)
I’ve noticed that the minimum working voltage of the BC127 IS 3.1V because of VCHG specification:
There is an example of a fixed voltage configuration, similar to my application:
Now, I don’t understand one thing, If I don’t use the battery charger function, why still connect the related charging pins (VCHG, VBAT_SENSE) to the power supply even though there are disabled?
Why limit the module’s minimum working voltage to VCHG specification if it not in use…?
Can I simply connect my 3.0V power supply to VBAT and VDD_PADS? (no USB connection is required)
Thanks a lot!
