Part Number: LM5067
Other Parts Discussed in Thread: TPS23523,

Would this part survive the following during surge testing-

    Hi Lauren,

    TPS23523 is ideal for surge protection. The ORing portion would block reverse current flow during -ve surges.

    LM5067 would need additional circuits as shown in Figure 9-11 and in some cases ORing controller at the input to support surges.
