Abstract:
1. A driver circuit arrangement, comprising: at least one driver circuit, comprising a first transistor of a first conductivity type having a source coupled to receive a first signal driven between a first potential and a second potential, and including a bulk portion containing the source and a drain of the first transistor; a second transistor of a second conductivity type having a drain coupled to the drain of the first transistor and a source coupled to a first power supply node that is coupled to receive the first potential; a third transistor of the second conductivity type having a drain coupled to the drain of the first transistor and a source coupled to the first power supply node; and a control device comprising a fourth transistor of the first conductivity type having a source coupled to a second power supply node and a drain coupled to the bulk portion of the first transistor, the control device configured to connect the bulk portion of the first transistor to the second power supply in an active mode of operation, and in a standby mode of operation to allow the bulk portion of the first transistor to electrically float and thereby electrically isolate the bulk portion of the first transistor from any direct voltage source.
