摘要： When an ECU applies to an igniter a plurality of pulse signals, the duty ratio of which is lower than a predetermined duty ratio, as a lock release signal, a latch circuit of a lock inhibition circuit stops applying a shut-off signal to a shut-off circuit thereby to release a lock condition of an IGBT. A drive main circuit thus restarts current supply to the IGBT. A condition detection circuit outputs to the ECU a condition signal corresponding to the current supplied while the IGBT is turned on.

摘要翻译： 当ECU向点火器施加占空比低于预定占空比的多个脉冲信号作为锁定解除信号时，锁定禁止电路的锁存电路停止向闭合施加截止信号 从而释放IGBT的锁定状态。 因此，驱动主电路重新开始向IGBT供电。 条件检测电路向ECU输出与IGBT导通时所提供的电流相对应的条件信号。
