    • PROBLEM TO BE SOLVED: To transfer the state of a power semiconductor element into an off-state by causing a semiconductor element used for pulldown to surely operate in the semiconductor integrated circuit device including the power semiconductor element. SOLUTION: A buffer circuit 29 is provided between a gate terminal of a transistor 26 used for pulldown and a threshold circuit 25 to which a gate signal is input. A voltage applied from an external battery power source 23 to an output terminal of the power semiconductor element 24 is fed to the buffer circuit 29 via a resistor element 28. A level of an on-signal output from the threshold circuit 25 is converted by the buffer circuit 29 into a higher voltage than a threshold of the transistor 26 used for pulldown and thereby even if a level of the gate signal is low, the transistor 26 used for pulldown certainly operates to turn off the power semiconductor element 24.

    • PURPOSE:To suppress power consumption low by minimizing an on-voltage drop of a collector catch diode of a main transistor (TR) of a base driving circuit of base current saving type to the extent that the power consumption is not increased. CONSTITUTION:The base driving circuit 9 of a Darlington TR8 functioning as the main TR is formed by an input signal amplifier 0, auxiliary TRs 3, 4, DC power supplies 10, 11 and the collector catch diode 5. The collector catch diode 5 is connected to a collector of the main TR8 and the type and the number are selected so as to minimize the on-voltage drop in the range where the power consumption of the TR8 is not increased. Thus, the loss of the main circuit is suppressed low.
    • 目的:通过将基极节电型的基极驱动电路的主晶体管(TR)的集电极捕获二极管的导通电压降低至功率消耗不增加的程度来抑制功率消耗。 构成:作为主TR的达林顿TR8的基极驱动电路9由输入信号放大器0,辅助TR 3,4,直流电源10,11和集电极捕捉二极管5构成。集电极捕捉二极管5为 连接到主TR8的集电极,并选择类型和数量,以便在TR8的功耗不增加的范围内最小化导通电压降。 因此,主电路的损耗被抑制得较低。
