    Hello Kami,

    If the LM3492 is communicating with a micro you can read the fault and turn off the other channel of the LM3492.  You can look at the TPS92692 used as a boost and watch the fault lines.  The TPS92682 can be used as two boosts with latched faults.  This can be monitored with the SPI bus on the TPS92682.

    I'm not sure which faults need to be latched, auto reset and/or one channel fault all channels fault.

    Best Regards,
