Other Parts Discussed in Thread: BQ25302,
Hi team,
1.I have noticed strange thing when battery is not connected with IC. Both battery and load is not connected --> Measured voltage across SW pins (inductor included) is ~4.15 Battery is not connected and Load is connected --> Measured voltage across SW pins (inductor included) is ~1.5 and not getting enough power to drive the load. The question is, how can i drive the load independent on presents of battery when VBUS is available?
2.i have additional enquiry on same part. i connected battery in reverse polarity, then it got short circuited and melted positive terminal from battery.. but circuit is fine.. But i don't understand how it got shorted . and what is the path for return current
Thank you very much for your help.
Best regards,
