Hello,
We have been using LMZ23610TZE/NOPB in our designs for years.
The recent manufacturing run for our mobile robot found 10/60 units to have faulty LMZ23610TZE/NOPB.
- 3/10 failures had LMZ23610TZE/NOPB that would not boot up
- 7/10 failures had LMZ23610TZE/NOPB that would drift, or slowly ramp up past their voltage setpoint
- Feedback resistors were confirmed to be correct
- There were no shorts on the board before startup
- The design was based on this: https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=DBE3875F7AA6310E
- All boards with the failed regulator had the following two date codes: 08AD85G3 or 08ADE8G3
Do you know if there is a way to check if we received counterfeit or faulty parts?
Thanks,
Kyle
