TLF35584 data sheet indicates "In case of over voltage at pin QTx, the corresponding tracker will be switched off, the event will be stored in an SPI status register (MONSF1) and an interrupt will be generated."
When the over voltage event ends, how/when does the tracker turns back on ?
- does tracker self recovers and turns on or
- does clearing the status register MONSF1 recovers the tracker ?

Dear User19903,
Apologize for the delay in the answer. This forum would actually not meant to be used for question related to PMICs and therefore the TLF35584.
Please contact a regional sales representative in future and he/she will fully support you on PMICs topics.
I managed to get your questions answered:
- TLF35584 will not re-activate the trackers autonomously unless there is an independent Move-to-INIT event (or higher severity event) that restarts the power sequencing after entering into INIT state. The application software can re-activate the trackers via SPI (DEVCTRL & DEVCTRLN) , of course assuming it is done in a reasonable way (restart-attempts strategy to avoid permanent overstress) based on the diagnostic flag (MONSFx) interpretation and application requirements.
- No, just clearing the MONSF1 flags for trackers does not reactivate them automatically. (refer to 1. for re-activation). The MONSFx register flags are only the voltage monitoring related diagnostic flags allowing the application software to assess the situation and identify appropriate system reaction.

Where are all the Infineon community members. There is no support ???
