Abstract: An apparatus includes a first comparator having first and second inputs, a first control input, an output, and a supply voltage terminal. A second comparator has first and second inputs, a second control input, and an output. The second comparator's first input is coupled to the first input of the first comparator. The second comparator's second input is coupled to the first comparator's second input. A switchover logic circuit has an input, a first output, a second output, and a third output. The input of the switchover logic circuit is coupled to the first inputs of the first and second comparators. The first output of the switchover logic circuit is coupled to the supply voltage terminal of the first comparator. The second output of the switchover logic circuit is coupled to the first control input. The third output of the switchover logic circuit is coupled to the second control input.
