Cross-conduction blocked power selection comparison/control circuitry with NTC (negative temperature coefficient) trip voltage

Power selection circuitry that may be employed in redundant power supplies. The power selection circuitry includes a comparator, a symmetric resistor array coupled between the comparator inputs and multiple input voltage sources, a plurality of first switching elements, and control logic/drive circuitry coupled between the comparator output and the first switching elements. The first switching elements connect a selected input voltage source to a load.
