Abstract: A voltage selector circuit is described. The voltage selector circuit includes a first voltage input, a second voltage input, and a voltage comparison input. The voltage selector circuit also includes a first voltage selector connected to an output. The first voltage selector is configured to compare the first voltage input and the second voltage input to the voltage comparison input. The voltage selector circuit also includes a second voltage selector connected to the output. The second voltage selector is configured to compare the first voltage input to the second voltage input using an early trigger, such that the second voltage selector is configured to switch on before the first voltage selector switches off.
