Patent ID: 11862630
Assignee: INFINEON TECHNOLOGIES AUSTRIA AG
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The semiconductor device of claim 1,
wherein the main bi-directional switch has four primary operational states: OFF/OFF in which both gates of the main bi-directional switch are off; ON/ON in which both gates of the main bi-directional switch are on; ON/OFF in which the first gate of the main bi-directional switch is on and the second gate of the main bi-directional switch is off; and OFF/ON in which the first gate of the main bi-directional switch is off and the second gate of the main bi-directional switch is on,
wherein the discharge circuit is configured to automatically discharge the semiconductor substrate to the first voltage terminal and/or the second voltage terminal responsive to the main bi-directional switch transitioning from the ON/OFF state or the OFF/ON state to the ON/ON state.
