| Ordering number : EN5708A Thick-Film Hybrid IC STK673-010-E Overview Bipolar Fixed-Current Chopper (external excitation PWM) Built-in Microstepping Control 3-Phase Stepping Motor Driver (sine wave drive) Output Current 2.4A The STK673-010-E is a 3-phase stepping motor driver hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage. It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit. The number of motor revolution can be controlled by the frequency of external clock input. 2, 2-3, W2-3 and 2W2-3-phase excitation modes are available. The basic step angle of the stepping motor can be separated as much as one-eighth 2-3phase to 2W2-3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise. Applications * As a 3-phase stepping motor driver for transmission and reception in a facsimile. * As a 3-phase stepping motor driver for feeding paper feed or for an optical system in a copying machine. * Industrial machines or products employing 3-phase stepping motor driving. Features * Number of motor revolution can be controlled by the frequency of external clock input. * 4 types of modes, i.e., 2, 2-3, W2-3 and 2W2-3-phase excitations, are available which can be selected based on rising of clock signals, by switching Highs and Lows of Mode A and Mode B terminals. * Setting a Mode C terminal Low allows an excitation mode that is based on rising and falling of a clock signal. By setting the Mode C terminal Low, phases that are set only by Mode A and Mode B can be changed to other phases as follows without changing the number of motor revolution: 2-phase may be switched to 2-3-phase; 2-3-phase may be switched to W2-3-phase; and W2-3-phase may be switched to 2W2-3-phase. * Phase is maintained even when the excitation mode is changed.

(3) and (7). Although the present hybrid IC is not damaged even when TU = 0 is mistakenly input in Excitation, other than Excitation Nos. (3) and (7), motor vibration or motor current may increase. * Timing charts for 3-phase stepping motor driver is illustrated on pages 9 to 13 for exemplary operations of Enable Hold, CW/CCW for Excitation Nos. (1), (2), (3), (4), (5) and (9), and Excitation No. (4). No.5708-5/15 STK673-010-E Notes On Use (1) Input terminal use of 5V system [RESET and Clock (timing of input signal upon rising of power supply)] The driver is configured to include a 5V system logic section and a 24V MOSFETs section. The MOSFETs on both VCC1 side and GND side are N-channels. Thus, the MOSFETs on the VCC1 side is provided with a charging pump circuit for generating a voltage higher than that of VCC1. When a Low signal is input to a RESET terminal for operating the RESET, the charging pump is stopped. After the release of the RESET (High input), it requires a period of 1.7ms to rise the charging pump. Accordingly, even when a Clock signal is input during the rising of the charging pump circuit, the MOSFET cannot be operated. Such a timing needs to be taken into consideration for inputting a Clock signal. An example of timing is shown in Figure 1. Rising of 5V power supply RESET signal input Clock signal > 10s > 1.7ms ITF00809 Figure 1. Timing chart of RESET signal and Clock signal When the RESET terminal switches from Low to High where a High period is 1.7ms or longer and the Clock input is conducted in a Low state, each phase current of the motor is maintained at the following values. Phase U phase V phase W phase Current in the case where the initial Clock signal is maintained at Low level (Other than 2-3-phase TU excitation) 0 -87% of peak current during normal rotation +87% of peak current during normal rotation Current in the case where the initial Clock signal is maintained at Low level (2-3-phase TU excitation) 0 -100% of peak current during normal rotation +100% of peak current during normal rotation Refer to the timing charts for operations. [Clock] Clock signals should be input under the following conditions so that all 9 types of excitation modes shown in the Excitation Mode Table. Input frequency range DC to 50kHz Minimum pulse width 10s High level duty 40 to 60% When Mode C is not used, it is an operation based on rising of the Clock and thus the above-mentioned condition of high level duty is negligible. A minimum pulse width of 10s or more allows excitation operation by Mode A and Mode B. Since the operation is based on rising and falling of the Clock under the use of Mode C, it is most preferable to set the high level duty to 50% so as to obtain uniform step-wise current widths. [Mode A, Mode B, Mode C and TU] These 4 terminals allow selection of excitation modes. For specific operations, refer to Excitation Mode Table and Timing Charts. No.5708-6/15 STK673-010-E [Hold, CW/CCW] Hold temporary holds the motor while a phase current of the motor is conducted, even when there are clock inputs of Low input. High input releases the hold, and the motor current changes again synchronizing with the rising of Clock signals. Refer to Timing Chart for exemplary operations. CW/CCW switches the rotational direction of the motor. Switching to High gives a rotational operation of CW, and Low gives a rotation operation of CCW. The timing of switching the rotation is synchronizes the rising of the clock signals. Refer to Timing Chart for exemplary operations. [Enable] High input renders a normal operation and Low input forcibly renders a gate signal of MOSFETs Low, thereby cutting a motor current. Once again High input renders a current to conduct in the motor. The timing of the current does not synchronize with the clock. Since Low input of Enable forcibly cuts the motor current, it can be used to cut a V-phase or W-phase while Clock is maintained in a Low level state after the RESET operation. Rising of 5V power supply RESET signal input Clock signal > 10s > 1.7ms Enable signal > 10s ITF00810 Figure 2. Input timings of RESET signal, Enable signal and Clock signal [Vref (Setting motor current peak value)] A peak value of a motor current IO is determined by R01, R02, VCC2 (5V) and the following set equation (I). Set equation of peak value of motor current IO IO peak = Vref / K (I) where Vref 0.5 x VCC2 K = 0.63 (V/A) Vref = VCC2 x Rox / (R01 + Rox) Rox = (R02 x 4.0k) / (R02 + 4.0k) * R02 is preferably set to be 100 in order to minimize the effect of the internal impedance (4.0k 30%) of STK673-010-E * K in the above-mentioned set equation varies with in 5 to 10% depending on the inductance L and resistance value R of the used motor. Check the peak value setting of IO upon actual setting. * Refer to Figure 4 for an example of Vref-IO characteristics (2) Allowable operating ranges of motor current Set the peak value of the motor current IO so as to lie within a region below the curve shown in Figure 5 on page 13. When the operation substrate temperature Tc is set to 105C, IO max should be 2.4A or lower and a Hold operation should be conducted where IO max is 2.0A or lower. For operation where Tc = 50C, IO max should be 4.0A or lower and a Hold operation should be conducted where IO max is 3.3A or lower. No.5708-7/15 STK673-010-E (3) Heat Radiation Design Heat radiation design for reducing the operation substrate temperature of the hybrid IC is effective in enhancing the quality of the hybrid IC. The size of a heat sink varies depending on the average power loss Pd in the hybrid IC. As shown in Figure 6 on page 14, Pd increases in accordance with the increase of the output current. Since the starting current and the stationary current coexist in an actual motor operation, Pd cannot be obtained only from the data shown in Figure 6. Therefore, Pd is obtained assuming that the timing of the actual motor operation is a repeated operation shown in the following Figure 3. T1 IO1 Positive rotation current T2 T4 T3 T1: Starting time of positive rotation T2: Stationary time of positive rotation T3: Starting time of reverse rotation T4: Stationary time of reverse rotation 0 IO3 T0: One cycle time of repeated motor operation P1: Pd of IO1 P2: Pd of IO2 IO2 Reverse rotation current T0 IO4 ITF00811 P3: Pd of IO3 P4: Pd of IO4 Figure 3. Timing Chart of Motor Operation The average power loss Pd in the hybrid IC upon an operation shown in Figure 3 can be obtained by the following equation (II): Pd = (T1 x P1 + T1 x P2 + T3 x P3 + T4 x P4) / T0 (II) When the value obtained by the above equation (II) is equal to or less than 3.4W and the ambient temperature Ta is equal to or lower than 60C, there is no need of providing a heat sink. Refer to Figure 7 for data of the operation substrate temperature when no heat sink is used. The size of the heat sink can be decided depending on c-a obtained by the following equation (III) and from Figure 8. c-a = (Tc max - Ta) / Pd (III) where Tc max: Maximum operation substrate temperature = 105C Ta: Ambient temperature of hybrid IC Although heat radiation design can be realized by following the above equations (II) and (III), make sure to check that the substrate temperature Tc is equal to or lower than 105C after mounting the hybrid IC into a set.
