    Hi Brian,

    The first device (BD820F5UEFJ-CE2) is an LDO. For the remaining 3 devices, these are undervoltage supervisor + timeout watchdogs, TI's latest and greatest undervoltage supervisor + timeout watchdog is the TPS35-Q1 IC. I would recommend TPS35AA38AGADDFRQ1 as a cross here.

    BD820F5UEFJ-CE2 LDO device N/A
    BD37B28FVM-CTR TPS35AA38AGADDFRQ1 Similar Device, package difference, topology is active-high vs active-low
    BD87B28G-CTR TPS35AA38AGADDFRQ1 Similar Device, package difference
    BD87B28FVM-CTR TPS35AA38AGADDFRQ1 Similar Device, package difference

    If you could get further understanding on watchdog timing needs (Watchdog time & output assert time) I can help with configuring those watchdog timings.

    Thanks,
    Joshua
