Using the TPS259241 and noticed that in a short circuit condition with the device operating in current limit mode, and after the device goes into thermal retry mode for a few minutes, it seems that the falling threshold for the EN pin is dropping. It looks to be tripping at 1V well below the 1.32V minimum.
The device is very hot during this event. If the device is allowed to cool down and operates into a normal load, the falling threshold is within spec.
Also, it was found that the only way to duplicate this was to have the device retry into a short and operate in overload for a few minutes. A current overload condition (not a short) did not seem to change the threshold.
Is this normal?
Vin = 8.4V nom (2-cell battery), Current limit set to 1.25A.
