Other Parts Discussed in Thread: TPS25940, TPS259230-41EVM

For  SUPPLY PROTECTION CONTROL to block reverse voltage and not in 9-16.8V range, is the TPS25940 is the right solution?

I do not really understand if the TPS25942 or 44 can help me more ?

Please advise/explain

    Hi Eli,
     
    The TPS25942(Preferred) can be used to protect from any reverse voltage. Here are the circuits.

    ·        Using a signal diode in control path of the device

     ·        Using a FET in series with power path. Here is how we implemented reverse polarity protection in the TPS259230-41EVM. You can try same with  the TPS25942.
