Hi NXP,
Could you please confirm whether a default fail-safe reaction (assertion of FSXB and RSTB) is configured for the following faults in the respective registers?
- M_TSD_FLG
- M_REG_FLG
- M_VSUP_FLG
Since the faults in the above registers are configured to provide an INTB indication, clarification is required on whether they also have any default fail-safe reaction, such as assertion of FSXB and/or RSTB.
Thanks,
Sivahari G
Hi RafaR,
I couldn't identify exactly which PN you were referring to?
I am using MFS2613AMDA6.
A fail-safe reaction such as FS0B (FSXB) and/or RSTB assertion is not automatically associated with the flag itself and depends on the corresponding fail-safe configuration.
Yes, absolutely for all regulators UV/OV fault has failsafe configuration registers "FS_I_OVUV_SAFE_REACTION1" and " FS_I_OVUV_SAFE_REACTION2 ". But Is there any provision to configure fail-safe reaction for all regulator Over Current Faults? since we have provisions to configure INTB masking/unmasking for those faults.
Example OC Faults(VBSTOV_I, VBSTOC_I, VPREOC_I, TRK1OC_I, COREOC_I)
Thanks,
Sivahari G
Hello
Good day!
I couldn't identify exactly which PN you were referring to, but in general this applies to all versions of FS26.
In summary, the flags in M_TSD_FLG, M_REG_FLG, and M_VSUP_FLG are interrupt sources by default. A fail-safe reaction such as FS0B (FSXB) and/or RSTB assertion is not automatically associated with the flag itself and depends on the corresponding fail-safe configuration, with TSD faults being an explicit example that can be configured to escalate into Deep Fail Safe.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
Hello Sivahari
Good day!
Unfortunately, the FS26 does not have an equivalent to FS_I_OVUV_SAFE_REACTION1/2 for currents, but, all LDOs and TRKs have a current limiter, so they should remain safe even if an overclock is detected, giving you time to check it. Depending on where it originates, a different process may begin, for example, VPRE.
I hope this information has helped you, please let me know if you need help with anything else.
Have a great day and best of luck.
