I am using LTC4416EMS#PBF to switch between a 12V power source and a USB power source. The 12V supply takes priority over the USB supply as long as it's above 4V.
My issue is that my 12V supply needs reverse polarity protection. The LTC4416 datasheet mentions reverse battery protection but doesn't talk about that much. My assumption is that V1 and V2 will be fine under reverse polarity, but I'm not sure about H1 and E1-2.
Here is my schematic (capacitors are not shown):
So will this be fine under reverse polarity from the 12V supply (CAB) or should I add circuitry before LTC4416 to protect against RPP?
