The framers put in protections against tyranny of the minority, yes. But it's not the electoral college (which Madison and Hamilton tried to get rid of after they saw how it behaved) or fptp voting, or minority rule.
You don't protect against tyranny of the majority by allowing minorities to dictate policy, that's just regular tyranny.
You protect against majorities by requiring supermajorities for all the most important functions of government: constitutional change, impeachment, and censure.
