Patent ID: 7268613

Claim:
An electronic circuit device comprising: a switching transistor having a gate terminal, a voltage source side terminal and an output terminal; a load impedance coupled to the output terminal; a voltage source connected to the voltage source side terminal; a gate input that selectively turns the switching transistor on or off based on voltage potential of the gate input relative to a threshold voltage that is required for the switching transistor to turn on; and means for automatically and dynamically connecting a body of the switching transistor to a highest potential voltage among a first potential voltage at the voltage source side terminal and a second potential voltage at the output terminal, wherein said means for automatically and dynamically connecting the body comprises: a resistor connected at one terminal to the voltage source side terminal of the switching transistor and at a second terminal to a body node connected to the body of the switching transistor; and a low voltage threshold (LVT) transistor having a source terminal connected to the body node and its drain and gate terminals connected to the output terminal of the switching transistor.
