Hello Sr,
As caption I made a standalone board used your chip BQ25970,however there is no charge current deliver out to Battery,even if rise up charge input to 9Vdc,and I printed related register's values and it reminds me 6 incorrect status as below,pls kindly give me some tips for further analysis,Thanks!
1:VBUS is too low for converter to start ,I certainly confirm input up to 9Vdc.
2:VBATREG active status is not active.
3:CONV switching start is not switching.
4:ADC conversion done status incomplete
5:ADC conversion done flag is incomplete.
6:IBATREG Active status is not active.
I double checked HW design,there no incorrections on peripheral circuit base on your technical information.
Best regards!
Peter
