Hi,
I have a custom nPM1100 borad and want to charge the battery. My schemetic shows here, I notice the battery cannot be charged. My shcemetic shows below:
I have confirmed some things are working:
1. I got 1.8V target at Vout.
2. My Vsys is 5V.
something confused me is:
1. I cannot charge the battery, the Vbat is 0.
2. I set to Vbus limit to 100 mA mode, but my real current is
3. When the PMIC is not working, if I have an external 1.8V source, whether the chip will broken in reverse voltage?
Thank you for your time!
