You could check out the LTC4358 ideal diode at https://www.analog.com/en/products/ltc4358.html
They have other ideal diode controller parts described in this brochure https://www.analog.com/media/en/news-marketing-col...
You might look at the LT8309 synchronous rectifier controller (no integrated FET) in a SOT-23 package. https://www.analog.com/en/products/lt8309.html
Yay. Thanks. A matter of knowing what the manufacturer calls them. Unfortunately, no high current internal FET ones, but it is a good start.
