Can any people who are good with circuits verify that all you need to build an active rectifier bridge would be comparators and MOSFETs? I really want to try this! Haha.

EDIT: Okay my research brings me to the following specs for a comparator:
Minimum supply voltage <= 6V (so it still functions when the engine is cranking under low battery), max supply voltage >16V (maybe good idea to pick the higher voltage ones to prevent damage from surges?), open drain or push-pull output, and 125C temperature rating.

STMicroelectronics TSX393 fits the bill? 2nA output seems too small, is push-pull better since it has more output current?
