Abstract
A low voltage drop unidirectional electronic valve constituted of: a first terminal; a second terminal; a first electronically controlled switch coupled between the first terminal and the second terminal; and a first charge pump arranged to close the first electronically controlled switch when the voltage potential at the first terminal is greater than the voltage potential at the second terminal by a first value. The first charge pump is arranged in a closed loop with the first electronically controlled switch so as to continuously maintain the voltage potential at the first terminal greater than the voltage potential at the second terminal by the first value.
