BQ24172: BQ24172 STAT blink issue

Other Parts Discussed in Thread: BQ24172,

Hi Sir,

 My customer is using BQ24172 for their 1 cell 2800mhA battery charging application.  5/13 boards test failed at their firse engineering test: STAT pin is blinking after over-night test. Battery at 3/5 boards are charged (has 4.2V), and the other 2 are not charged.

1. Please help to check if there's any issue at their circuit design.

2. By customer's feedback, they see two different blinking signal. Is there any special meaning at the two kind of waveform?

  

Any other things we have to check at customer's board for debugging/clear? 

Thanks for your kindly help.

Regards,

Gary Teng
