All rights reserved.Single Gauge DriverThe 33977 is a Serial Peripheral Interface (SPI) Controlled, stepper motor gauge driver Integrated Circuit (IC). This monolithic IC consists of a dual H-Bridge coil driver and its associated control logic. The H-Bridge drivers are used to automatically control the speed, direction, and magnitude of current through the coils of a two-phaseinstrumentation stepper motor, similar to an MMT-licensed AFIC 6405 of Switec MS-X156.xxx motor.The 33977 is ideal for use in instrumentation systems requiring distributed and flexible stepper motor gauge driving. The device also eases the transition to stepper motors from air core motors by emulating the damped air core pointer movement.

This monolithic stepper IC consists of [deleted two per D. Mortensen] a dual output H-Bridge coil driver [deleted plural s for accurate tense] and theassociated control logic. The dual H-Bridge driver is used to automatically control the speed, direction, and magnitude of current through the coils of a two-phase instrumentation stepper motor, similar to an MMT-licensed AFIC 6405 of Switec MS-X 156.xxx motor.FUNCTIONAL PIN DESCRIPTIONCOSINE POSITIVE (COS0+)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.COSINE NEGATIVE (COS0-)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.SINE POSITIVE (SIN+)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.SINE NEGATIVE (SIN-)The H-Bridge pins linearly drive the sine and cosine coils of a stepper motor, providing four-quadrant operation.GROUND (GND)Ground pins.CHIP SELECT (CS)The pin enables communication with the master device. When this pin is in a logic [0] state, the 33977 is capable of transferring information to, and receiving information from, the master. The 33977 latches data in from the Input Shift registers to the addressed registers on the rising edge of CS.The output driver on the SO pin is enabled when CS is logic [0]. When CS is logic high, signals at the SCLK and SI pins are ignored and the SO pin is tri-stated (highimpedance). CS will only be transitioned from a logic [1] state to a logic [0] state when SCLK is logic [0]. CS has an internal pull-up (I UP ) connected to the pin, as specified in the section of the Static Electrical Characteristics Table.SERIAL CLOCK (SCLK)SCLK clocks the Internal Shift registers of the 33977device. The SI pin accepts data into the Input Shift register on the falling edge of the SCLK signal, while the Serial Output pin (SO) shifts data information out of the SO Line Driver on the rising edge of the SCLK signal. It is important that the SCLK pin be in a logic [0] state whenever the CS makes any transition.SCLK has an internal pull down (l DWN ), as specified in the section of the Static Electrical Characteristics Table. When CS is logic [1], signals at the SCLK and SI pins are ignored and SO is tri-stated (high impedance). Refer to the data transfer Timing Diagrams on page 9.SERIAL OUTPUT (SO)The SO data pin is a tri-stateable output from the Shift register. The Status register bits are the first 16 bits shifted out. Those bits are followed by the message bits clocked in FIFO, when the device is in a daisy chain connection or being sent words that are multiples of 16 bits. Data is shifted on the rising edge of the SCLK signal. The SO pin will remain in a high impedance state until the CS pin is put into a logic low state.SERIAL INPUT (SI)The SI pin is the input of the SPI. Serial input information is read on the falling edge of SCLK. A 16-bit stream of serial data is required on the SI pin, beginning with the mostsignificant bit (MSB). Messages that are not multiples of 16 bits (e.g., daisy chained device messages) are ignored. After transmitting a 16-bit word, the CS pin must be de-asserted (logic [1]) before transmitting a new word. SI information is ignored when CS is in a logic high state.RETURN TO ZERO (RTZ)This is a multiplexed output pin for the non-driven coil, during a Return to Zero (RTZ) event.VOLTAGE (VDD)The SPI and logic power supply input will work with 5.0 V supplies.RESET (RST)If the master decides to reset the device, or place it into a sleep state, the RST pin is driven to a Logic [0]. A Logic [0] on the RST pin forces all internal logic to the known default state. This input has an internal active pull-up.VOLTAGE POWER (VPWR)This is the power supply pin.FUNCTIONAL DESCRIPTIONFUNCTIONAL INTERNAL BLOCK DESCRIPTION (OPTIONAL) FUNCTIONAL INTERNAL BLOCK DESCRIPTION (OPTIONAL)Figure 6.

The two-phase stepper motor has maximum allowable velocities andacceleration and deceleration. The purpose of the steppermotor state machine is to drive the motor with the maximumperformance while remaining within the motor’s voltage,velocity, and acceleration constraints.A requirement of the state machine is to ensure thedeceleration phase begins at the correct time and pointerposition. When commanded, the motor [will deleted PV]accelerates constantly to the maximum velocity, and then itmoves toward the commanded position at the maximumvelocity. Eventually, the pointer reaches the calculatedlocation where the movement has to decelerate, safelyslowing to a stop at the desired position. During thedeceleration phase, the motor does [will deleted PV] notexceed the maximum deceleration.During normal operation, both stepper motor rotors aremicrostepped at 24 steps per electrical revolution, illustratedin Figure 7. A complete electrical revolution results in twodegrees of pointer movement. There is a second smaller[parentheses removed-unnecessary] state machine in the ICcontrolling these microsteps. The smaller state machinereceives clockwise or counter-clockwise index commands attimed intervals, thereby stepping the motor in the appropriatedirection by adjusting the current in each coil. Normalizedvalues are provided in Table 5.Figure 7. Clockwise MicrostepsTable 5.

The time between steps defines the motor velocity and the changing time defines the motor acceleration.The state machine uses a table to define the allowed time and the maximum velocity. A useful side effect of the table is that it also allows the direct determination of the position at which the velocity should reduce to stop the motor at the desired position.Motor motion equations follow: [reworded for efficient use of space](The units of position are steps and velocity and acceleration are in steps/second and steps/second2.) From an initial position of 0 with an initial velocity (u), the motor position (s) at a time (t) is:For unit steps, the time between steps is:This defines the time increment between steps when the motor is initially traveling at a velocity u. In the ROM, this time is quantized to multiples of the system clock by rounding upwards, ensuring acceleration never exceeds the allowed value. The actual velocity and acceleration is calculated from the time step actually used. Using:andand solving for v in terms of u, s, and t gives:The correct value of t to use in the equation is thequantized value obtained above.From these equations, a set of recursive equations can be generated to give the allowed time step between motor indexes when the motor is accelerating from a stop to its maximum velocity.Starting from a position p of 0 and a velocity v of 0, these equations define the time interval between steps at each position. To drive the motor at maximum performance, index commands are given to the motor at these intervals. A table is generated giving the time step *t at an index position n. Note: [chgd for format consistency AND deleted that as PV] For p n = n, on the nth step, the motor [has deleted as PV] indexed by n positions and has been accelerating steadily at the maximum allowed rate. This is critical because it also indicates the minimum distance the motor must travel while decelerating to a stop. For example, the stopping distance isalso equal to the current value of n.The algorithm of pointer movement can be summarized in two steps:1.The pointer is at the previously commanded positionand is not moving.2. A command to move to a pointer position (other thanthe current position) has been received. Timed indexpulses are sent to the motor driver at an ever-increasing rate, according to the time steps in Table 6, until:aThe maximum velocity (default or selected) isreached after which the step time intervals will nolonger decrease.bThe distance in steps that remain to travel are less than the current step time index value. The motorthen decelerates by increasing the step timesaccording to Table 6 until the commandedposition is reached. The state machine controlsthe deceleration so that the pointer reaches thecommanded position efficiently.An example of the velocity table for a particular motor is provided in Table 6.

The divider (resistors R 1 and R 2) from V REF makes the reference voltage, which will be provided to the noninverted input of the error amplifier, less than output voltage. In the fixed voltage source where the output voltage will be fed back to the error amplifier directly as shown in figure 1. Output voltage will be divided VREF since the output voltage is equal to the reference voltage.Thus, the output voltage V OUT is:V OUT = nV REF , n =R 212Figure 1 Low Voltage (2 to 7 V) RegulatorHigh Voltage (7 to 37 V) Regulator: Figure 2 shows the construction of a regulator whose output voltageis higher than the reference voltage, V REF . V REF is added to the non-inverted input of the error amplifier via a resistor, R 3. The feedback voltage is produced by dividing the output voltage with resistors R 1 and R 2.Thus, the output voltage V OUT is:V OUT =, n =V REF R 212Figure 2 High Voltage (7 to 37 V) RegulatorHA17723/F/P6Negative Voltage Regulator: Figure 3 shows the construction of a so-called negative voltage regulator,which generates a negative output voltage with regard to GND. Assume that the output voltage, –V OUT ,increases in the negative direction. As the voltage across the R 1 is larger than that across the R 3, which provides the reference voltage, the output current of the error amplifier increases. In the control circuit, the impedance decreases with the increase of input current, which makes the base current of the external transistor Q approach GND. As a result, the output voltage returns to the established value and output voltage is stable.The output voltage –VOUT of this circuit is:–V OUT = –= –V REF×VREF×R 334(R 1 + R 2) · (R 3 + R 4)234412R 1 + R 2R 3 + R 4R 3R 1Figure 3 Negative Voltage RegulatorHow to Increase the Output Current: To increase the output current, you must increase the current capacity of the control circuit.

Figure 10 shows the circuit of a floating-type fixed voltage source. Considering the stabilization in this circuit, assume that the output voltage increases. At the input terminal of the error amplifier the non-inverted input will become low compared with the inverted input, and the output current of the error amplifier decreases. Then, the current from the terminal V Z in the control circuit decreases. As a result the base current of the external resistor Q 1 will decrease and collector current will decrease, controlling increase of the output voltage.The output voltage V OUT in the circuit in figure 10V OUT =– 1 V REF×R 1 + R 2R 3 + R 4R 4R 1Figure 11 is the circuit diagram of a negative fixed voltage source in floating type.Figure 10 Positive Voltage Floating RegulatorFigure 11 Negative Voltage Floating RegulatorFixed Voltage Source with Reduction Type Current LimiterFigure 12 Fixed Voltage Source with Reduction Type Current LimiterFigure 13 Current Control Characteristics of Fixed Voltage Sourcewith Reduction Type Current LimiterFixed Voltage Source Switching External ControlFigure 14 Fixed Voltage Source Switching External ControlFigure 15 Operating Characteristics of Fixed Voltage Source Switching External ControlCharacteristic CurvesPackage DimensionsCautions1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.
