Hello Team,
If the TPS1H100-Q1 trips overcurrent it appears from Table 1 that the switch will have a retry strategy to automatically recover.
Can you share details on how this recovery strategy works?
- How much delay is there between an overcurrent event and a retry?
- Will the switch every "give up" or will it retry forever?
- Any further details on how the actual retry occurs would be helpful
Thanks,
David
Hi David,
When overcurrent happens, it will be clamped at the set current limit value.
If the overcurrent eventually run into a thermal shutdown, then the device will shutdown and retry after thermal hysteresis. During the time, the current limit will be half of the internal value or external set value. If temperature falls below the status reset temp, then the current limit value will be reset to original value. If the device kept in the thermal shutdown range, then the device will retry forever.

Yichi
