Abstract
A selection circuit having a comparator with comparator inputs connected to first and second voltage inputs), respectively, and a comparator output connected to a control input of a first controllable switch and an inverter. The selection circuit also has a second controllable switch having a second control input connected to the inverter. The first voltage input is connectable to a selection circuit output by the first controllable switch and the second voltage input is connectable to the selection circuit output by the second controllable switch. The inverter has a power supply connector connected to the first voltage input and the comparator has a power supply connector connected to the second voltage input.
