TPS65910: NRESPWRON behavior

Part Number: TPS65910
Other Parts Discussed in Thread: TPS65218D0

Hi Team,

Is the NRESPWRON's output integrated of voltage supervising results of each bus?
I want to check if we need to put some supervisor on the voltage buses or not.

Regards,

    No, the TPS65910 does not have supervisors on each rail. The NRESPWRON will be high when the power sequence is complete (based on time and internal logic for sequencing). If a rail is out of tolerance, the TPS65910 has no knowledge of this and will continue the sequence.

    The TPS65218D0, on the other hand, integrates supervisors for each rail and can be used for Sitara AM335x and AM437x applications.
