    • An improved solenoid driver control circuit is disclosed in which solenoid current is sensed and provided as an input to a comparator means comprising two separate comparators (24, 25). The comparator means receives a solenoid current sense signal (45) and maximum and minimum reference threshold levels which determine maximum and minimum current limits (I max , I min ;.H max , H min ) for solenoid current during initial
      pull-in excitation and subsequent hold excitation. Pull-in time (T₁) is defined by a monostable multivibrator (33) reacting to a control pulse (41) to produce a predetermined pull-in time pulse (43) such that the pull-in time is independent of sensed solenoid current. During pull-in time a boost driver switch (53) applies high boost voltage to a power source terminal (16) which supplies solenoid current, and in response to achieving the maximum pull-in current limit (I max ) lower battery voltage is provided at the power source terminal. If the maximum pull-in current limit does not occur within a predetermined time (t b1 ) after pull-in initiation (at t₀), then the lower battery voltage is applied to the power source terminal at that time. The above configuration insures rapid initial solenoid response while minimizing power dissipation and circuit stress.
    • 公开了一种改进的螺线管驱动器控制电路,其中感测螺线管电流并将其提供给包括两个单独的比较器(24,25)的比较器装置的输入。 比较器装置接收螺线管电流检测信号(45)和最大和最小参考阈值电平,其确定在初始引入激励和随后的保持激励期间螺线管电流的最大和最小电流限制(Imax,Imin; .Hmax,Hmin)。 引入时间(T1)由与控制脉冲(41)反应的单稳态多谐振荡器(33)定义,以产生预定的引入时间脉冲(43),使得引入时间与感测的电磁线圈无关。 在拉入时间期间,升压驱动器开关(53)对提供螺线管电流的电源端子(16)施加高升压电压,并且响应于实现最大引入电流限制(Imax),电池电压提供在 电源端子。 如果在引入启动(在t0)之后的预定时间(tb1)内没有发生最大引入电流限制,则此时电池端子施加较低的电池电压。 上述配置确保了快速的初始电磁线圈响应,同时最小化功耗和电路应力。
