http://onsemi.com OPERATING DESCRIPTION The MC33030 was designed to drive fractional horsepower DC motors and sense actuator position by voltage feedback. A typical servo application and representative internal block diagram are shown in Figure 17. The system operates by setting a voltage on the reference input of the Window Detector (Pin 1) which appears on (Pin 2). A DC motor then drives a position sensor, usually a potentiometer driven by a gear box, in a corrective fashion so that a voltage proportional to position is present at Pin 3. The servo motor will continue to run until the voltage at Pin 3 falls within the dead zone, which is centered about the reference voltage. The Window Detector is composed of two comparators, A and B, each containing hysteresis. The reference input, common to both comparators, is pre−biased at 1/2 V CC for simple two position servo systems and can easily be overridden by an external voltage divider. The feedback voltage present at Pin 3 is connected to the center of two resistors that are driven by an equal magnitude current source and sink. This generates an offset voltage at the input of each comparator which is centered about Pin 3 that can float virtually from V CC to ground. The sum of the upper and lower offset voltages is defined as the window detector input dead zone range. To increase system flexibility, an on−chip Error Amp is provided. It can be used to buffer and/or gain−up the actuator position voltage which has the effect of narrowing the dead zone range. A PNP differential input stage is provided so that the input common−mode voltage range will include ground. The main design goal of the error amp output stage was to be able to drive the window detector input. It typically can source 1.8 mA and sink 250 /C0109A. Special design considerations must be made if it is to be used for other applications. The Power H−Switch provides a direct means for motor drive and braking with a maximum source, sink, and brake current of 1.0 A continuous. Maximum package power dissipation limits must be observed. Refer to Figure 15 for thermal information. For greater drive current requirements, a method for buffering that maintains all the system features is shown in Figure 30. The Overcurrent Monitor is designed to distinguish between motor startup or locked rotor conditions that can occur when the actuator has reached its travel limit. A fraction of the Power H−Switch source current is internally fed into one of the two inverting inputs of the current comparator, while the non−inverting input is driven by a programmable current reference. This reference level is controlled by the resistance value selected for R OC, and must be greater than the required motor run−current with its mechanical load over temperature; refer to Figure 8. During an overcurrent condition, the comparator will turn off and allow the current source to charge the delay capacitor, C DLY. When CDLY charges to a level of 7.5 V , the set input of the overcurrent latch will go high, disabling the drive and brake functions of the Power H−Switch. The programmable time delay is determined by the capacitance value−selected for C DLY. tDLY /C0043 Vref CDLY IDLY(source) /C0043
7.5 CDLY
5.5 μA /C00431.36 CDLY in μF This system allows the Power H−Switch to supply motor startup current for a predetermined amount of time. If the rotor is locked, the system will time−out and shutdown. This feature eliminates the need for servo end−of−travel or limit switches. Care must be taken so as not to select too large of a capacitance value for CDLY. An overcurrent condition for an excessively long time−out period can cause the integrated circuit to overheat and eventually fail. Again, the maximum package power dissipation limits must be observed. The overcurrent latch is reset upon powerup or by readjusting VPin 2 as to cause V Pin 3 to enter or pass through the dead zone. This can be achieved by requesting the motor to reverse direction. An Overvoltage Monitor circuit provides protection for the integrated circuit and motor by disabling the Power H−Switch functions if VCC should exceed 18 V . Resumption of normal operation will commence when VCC falls below 17.4 V . A timing diagram that depicts the operation of the Drive/Brake Logic section is shown in Figure 18. The waveforms grouped in [1] show a reference voltage that was preset, appearing on Pin 2, which corresponds to the desired actuator position. The true actuator position is represented by the voltage on Pin 3. The points V1 through V4 represent the input voltage thresholds of comparators A and B that cause a change in their respective output state. They are defined as follows: V1 = Comparator B turn−off threshold V2 = Comparator A turn−on threshold V3 = Comparator A turn−off threshold V4 = Comparator B turn−on threshold V1−V4 = Comparator B input hysteresis voltage V2−V3 = Comparator A input hysteresis voltage V2−V4 = Window detector input dead zone range |(V2−VPin2) − (VPin2 − V4)| = Window detector input voltage
