Claim:
1. A power device, comprising: an upper power module coupled to a first node, a second node and a first control node via first interconnections, the upper power module being controlled by a first driving signal at the first control node to turn on/off a first current path between the first node that receives a first supply voltage and the second node; a lower power module coupled to the second node, a third node and a second control node via second interconnections, the lower power module being controlled by a second driving signal at the second control node to turn on/off a second current path between the second node and the third node that receives a second supply voltage that is lower than the first supply voltage, wherein the first interconnections are inductively coupled to prevent a turn-on of the upper power module when the first driving signal is at a first voltage level to turn off the upper power module and the second driving signal is at a second voltage level to turn on the lower power module.
