Based on the three voltage, three control signals should be generated to trigger three switches. So i think use two comparators. The trigger voltage of first comparator is 1.2. if the out of it is high, another comparator with 2.4v trigger voltage is needed. but the method is not good. is there another notive method? Thank you all
