Tool/software:
I'm experiencing an error with the TPS25983. Namely that the auto retry reset logic of 2 faults far apart in time is not behaving as intended.
The logic should behave as follows (A snippet from the Datasheet p. 30):
"The auto-retry logic has a mechanism to reset the count to zero if two consecutive faults occur far apart in time. This mechanism makes sure that the auto-retry response to any later fault is handled as a fresh sequence and not as a continuation of the previous fault. If the fault which triggered the shutdown and subsequent auto-retry cycle is cleared eventually and does not occur again for a duration equal to 7 retry delay timer periods starting from the last fault, the auto-retry logic resets the internal auto-retry count to zero."
In my case i have set ITIMER and RETRY_DLY to 1 second. But faults that happen more than 7 seconds after the last fault still result in a shut down.
I have attached a snippet from the schematic and testplan.
For the tests the pump was replaced with an electronic load.
Can you help me identify why these faults are not handled as independent faults?
If you need further clarification or have other questions please don't hesitate to ask.
Best regards
