Patent ID: 8476956

Claim:
A semiconductor switch comprising: a power supply section configured to generate a first potential higher than a positive power supply potential, and a negative second potential; a driver connected to the power supply section and configured to output a control signal according to a terminal switching signal, wherein a high level potential of the control signal is set to correspond to the first potential and a low level potential of the control signal is set to correspond to the negative second potential; and a switch section configured to receive the control signal and switch a connection between terminals, the driver comprising: a first level shifter having a first high-side switch and a first low-side switch, wherein the first high-side switch and the first low-side switch are connected in series between the first potential and a third potential, and the first high-side switch and the first low-side switch are exclusively turned on to each other according to the terminal switching signal; a second level shifter having a second high-side switch and a second low-side switch, wherein the second high-side switch and the second low-side switch are connected in series between the first potential and the negative second potential, and the second high-side switch and the second low-side switch are exclusively turned on to each other according to an output potential of the first level shifter; and a first circuit configured to supply the positive power supply potential to the second low-side switch according to the terminal switching signal, before a potential of the control signal is changed, and turn on the second low-side switch.
