I am using the TPS2595 as a fuse for a small battery pack. The charger is setup to charge the battery through the pass transistor body diode and is current limited to 1.2A. I am seeing some batteries fail QC checks after being stored briefly and was able to root cause it to an excessive current draw on the TPS2595. To verify the UVLO resistor chain was not causing this, the upper resistor was removed, which should put the part in a low power mode. I am seeing 28mA of quiescent draw though, with no output load and no charger connected.
I am trying to determine if the charge path through the body diode could cause this (not sure how it would), or what else could cause the current draw to be 1000X what is stated in the datasheet. Any ideas on the root cause and how to abate the issue is much appreciated.
Thanks!
