Part Number:BQ78350-R1
I wrote a post yesterday on this component, but it must not have saved because I cannot find it today. I have implemented a demo design utilizing the BQ78350-R1 paired with the BQ76930. During initial power up/testing, we are finding a short circuit between the REGOUT (2.5V) regulator and ground. Upon investigation, this short circuit (<5 ohms) went away after removing the BQ78350. I have had this happen on 4 or 5 PCBAs, a couple of them I didn't even finish building the packs because I noticed a couple of circuits getting hot with the power draw trying to feed the short circuit. There is one pack that we were able to communicate with for a little while, but now that is not operational and the same rail is shorted.
Any ideas on where to start investigating what can be causing this damage to the BQ78350 device? Additionally, I have a separate 3.3V regulator on the output of the FETs that is also seeing a short circuit on the same boards, still unsure how that is happening as well.
Thanks, Mike
