Semiconductor integrated circuit device

A semiconductor integrated circuit device comprising:

• a power semiconductor element including an output terminal supplied with a power supply voltage externally and which applies an output current to the output terminal based on a gate signal input externally;
• a pull-down semiconductor element which pulls down a gate voltage of the power semiconductor element to an off level of the power semiconductor element based on the gate signal;
• a threshold circuit which outputs an on-signal or an off-signal for turning on or off the pull-down semiconductor element based on the gate signal;
• a buffer circuit which converts the level of the on-signal output from the threshold circuit into a level for turning on the pull-down semiconductor element;
• and
• a resistive element which is connected to the output terminal of the power semiconductor element;
• wherein the buffer circuit is driven by a voltage extracted from the output terminal through the resistive element.
