摘要： 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.

摘要： A MOS differential to single ended converter circuit (24) supplies a single output signal in response to receiving first and second differentially related currents. The converter includes first and second MOS transistors (26,28). First and second bipolar transistors (38,40) each having first, second and control electrodes are provided for limiting the voltage swing at the drain of the second MOS transistor. The control and first electrodes of the first bipolar transistor are coupled respectively to the drains of the first and second MOS transistors while the control and first electrodes of the second bipolar transistor are respectively coupled to the drains of the second and first MOS transistors with the second electrodes of the two bipolar transistors being coupled to an additional common terminal.
