Referring to TIDA-010224 - Low-Power Wireless Camera Reference Design
I see there's (Q1) SI2323DS in front of (U3) LM66100DCKT input pin
LM66100 datasheet describes it as "5.5-V, 1.5-A 79-mΩ, Low IQ Ideal Diode With Input Polarity Protection"
Why Q1/FET is needed/ used in addition to U3's Input polarity protection?
I see it (the FET) is not used in LM66100EVM - so even more curious...
Please advise. Thanks.
