摘要： A drive circuit includes a plurality of output drive terminals and a plurality of push-pull circuit stages. Each of the push-pull circuit stages includes a pair of complementary transistors having a common terminal connected to a respective output drive terminal. The drive circuit further includes a plurality of first transistors connected in series with at least one of the pair of complementary transistors of the push-pull circuit stages, respectively, and a common second transistor. The common second transistor is connected with each of the plurality of first transistors to form a current mirror circuit. The drive circuit further includes a mirror current setting circuit for setting a mirror current flowing through the common transistor

摘要： A load drive circuit which can operate at high speed with low consumption current while performing the gate-to-source over voltage protection for its load driving field-effect transistor. A Zener function device is connected between the gate and the source of the load driving field-effect transistor, and an on/off-switch circuit to supply either on-potential or off-potential to the gate of the field effect transistor is provided. The current flowing through the Zener function device when the load driving field-effect transistor is conductive is limited by the on/off-switch circuit.
摘要翻译：一种负载驱动电路，能够以低功耗电流高速运行，同时对其负载驱动场效应晶体管进行栅极到源极过电压保护。齐纳功能器件连接在负载驱动场效应晶体管的栅极和源极之间，并且提供了向场效应晶体管的栅极提供导通或截止电位的导通/截止开关电路。当负载驱动场效应晶体管导通时，流过齐纳函数器件的电流受到导通/截止开关电路的限制。
