Abstract
A power switch device includes a first terminal intended to be connected to a source of a first supply potential, a second terminal configured to supply a second potential, and a third terminal intended to be connected to a second source of a third supply potential. The device includes a first PMOS transistor having a source connected to the second terminal and a drain connected to the third terminal, a second PMOS transistor having a source connected to the second terminal, and a third PMOS transistor having a source connected to the first terminal and a drain connected to the drain of the second transistor. A control circuit generates gate control signals to control operation of the first, second and third PMOS transistors dependent on the first, second, and third supply potentials.
