BQ24610: BQ24610

Part Number: BQ24610

Hi,

We are using BQ24610 in our design.
Attached the schematics FYR.

The circuit was working fine without any issue.
Few months back we have noticed that the Power Good of the IC is not working properly.
It will show always as AC absent as the IC is not pulling the PG low.
All other functions works properly. And we have replaced the IC and it worked fine.

Yesterday, we heard from our customer that in 3 more systems this issue is happening.
Can you let us know why this issue happens and what we can do stop this happening in other boards?

Thanks & Regards,
Shafeeq

Hi Shafeeq,

I haven't seen this issue before. Can you take test data from the units? please take a waveform of VCC, PG, STAT1, PH when IC is charging.

Hi Kedar,

Currently the system with issues are with our customer. We found this issue in only one system few months back and we replaced the BQ24610 that time only. So there is no systems with us currently. So once we receive the defected system from customer, will try to capture the required details and will share.

Thanks & Regards,
Shafeeq

Hi Shafeeq,

Please update when you have test data. This will give us good info on what is happening. I will place the thread on hold till you are able to update. Once you have results, a reply will open the thread back up. Thanks!
