ʀDescription of operations

Description of capstan operation
1. Hall input - output
The Hall sensor input signal of the three-phase, is amplified by the Hall amplifier to produce a drive signal
waveform. This drive signal is amplified, once again, by the output amplifier to supply a drive current for the motor
coil. Output current is a trapezoidal waveform. Due to the trapezoidal waveform, gaps are generated in the
magnetic field by the three-phase coil, which causes a slight irregularity of rotation. In operation, the triangle wave
is superimposed upon the trapezoidal output waveform. (Torque ripple cancellation)
2. Torque control
Output current can be controlled by the voltage applied to C.EC (torque control terminal).

3. Brake
When the C.FBR terminal is set to M, each output voltage becomes low and the brake is applied.
Brake command voltage: C.FBR 1.3V to 1.7V
4. Motor power supply control function
In order to use power effectively (as well as to prevent exceeding permissible dissipation of IC), it is required to
change supply voltage according to output current, i.e. to reduce supply voltage when current output is low, and
increase when current output is high, thereby preventing extra voltage from being applied between Drain and
Source of output stage MOS. Power supply control function (VS terminal) is installed for this purpose. In this
function, the voltage between Drain and Source of upper MOS of output stage is detected, and output to VS
terminal as a power supply control signal. This gain signal is multiplied several times by DC/DC, for controlling
motor power supply.
5. Output TR saturation preventing circuit
This circuit is used to operate output MOS in linear region. It has good dynamic range from a low to high current,
and provides a good rotating performance under overload, etc.
ꢀ
Description of cylinder operation
1. Back electromotive force detecting comparator (BEMF)
Compares the output voltage of the motor with the midpoint potential BEMF and detects the position of the rotor
and stator (magnet and coil). Further, the BEMF is provided with hysteresis, which can be set by resistor RD.com,
connected to D.COM terminal.
2. Phase switching logic
Synthesizes the output from three-phase BEMF force detecting comparator. The noise pulse of BEMF by the motor
is eliminated by MASK signal, generated by D.SL terminal 1 and 2 with reference to each position-detected signal.
Only the rising edge of masked synthetic output is used as a signal for the secondary counter. While output from
secondary and drive signal is synthesized, FG signal is generated every 60 degrees (electric angle).
3. Slope
D.SL terminal 1 and 2 are charged and discharged in synchronization with the timing of the internal FG signal. For
driving soft switching, slope is applied to output current waveform by the slope rate of D.SL terminal 1 and 2.
MASK signal is generated by charging and discharging waveform of D.SL terminal 1 and 2. MASK signal L is
output only when the charging and discharging waveform of D.SL terminal 1 and 2 is clamped at L level, when
MASK is canceled. Otherwise, H is output and MASK is applied, and noise pulse by back electromotive force of
motor is removed.
4. Detection circuit - start signal synthesizing
When a capacitor is connected to D.DETECT terminal, charging and discharging are performed. When the motor is
stopped, D.DETECT terminal repeats charging and discharging between Low-level and High-level. Only the rising
edge of square wave (SEL) that is synchronized with D.DETECT terminal, is compared with rising edge of
synthesized output of BEMF detecting comparator. When the motor is stopped, BEMF detecting comparator is not
output. Therefore, the edge of SEL signal is input to secondary counter and attempts to force the motor to rotate
(synchronized mode). Before the motor rotates and D.DETECT terminal reaches High-level, BEMF detecting
comparator detects BEMF motor. When synthetic output of BEMF detection comparator is output, D.DETECT
terminal starts discharging on the corresponding edge. When Low-level is reached, charging is started again, and
discharging is started on the edge of BEMF detecting comparator output. Here the edge of synthetic output of
BEMF comparator is input to secondary counter, and the motor rotates. (BEMF mode)
12/16
5. Torque control
Output current can be controlled by the voltage applied to D.EC (torque control terminal), as with capstan
assembly.
6. Motor power supply control function
In order to use power effectively (as well as to prevent exceeding permissible dissipation of IC), it is required to
control supply voltage according to output current. For example, reduce supply voltage when current output is low,
and increase when current output is high, thereby preventing extra voltage from being applied between Drain and
Source of output stage MOS. Power supply control function (VS terminal) is used for this purpose. In this function,
the voltage between Drain and Source of upper MOS of output stage is detected, and sent to VS terminal as a
power supply control signal. This gain signal is multiplied several times by DC/DC, for controlling motor power
supply.
7. Output TR saturation preventing circuit
This circuit is used to operate output MOS in linear region. It has good dynamic range from a low to high current,
and provides a good rotating performance under overload, etc.

Description of loading assembly operation
1. L.FBR input - output

voltage input to L.FBR.
2. Loading assembly output H voltage control

Output H voltage setting range
ʀApplication part selecting procedure
Selection of constant in the example of recommended circuit is shown below:
1) Capstan hall bias resistor (RH1 and RH2)ꢀ
The amplitude and bias point of hall element can be set by hall bias resistor. Hall amplitude varies with hall element
in use even when the same bias resistor is used, therefore adjust the bias resistor so that the amplitude of hall
element is 50 - 100mvp-p as well as within the range of hall amplifier in-phase input voltage range of capstan
assembly (1.2 - VCC-1.1V).
Vcc
Upper limit of hall input voltage range (VCC-1.1V)
Amplitude of hall element
Lower limit of hall input voltage range (1.2V)
GND
2) Capstan C.RCC resistor
Canceling rate of torque ripple canceling circuit of capstan assembly can be adjusted by the resistor equipped
externally on C.RCC terminal. Select the optimum value, considering the vibrations, when the IC is mounted to the
motor. The optimum value depends on the motor, while 2k ꢁ to 4k ꢁ is recommended.
3) Cylinder D.COM terminal connection terminal
By inserting a resistor in the middle point of D.COM terminal and motor, the BEMF detecting comparator can also
generate hysteresis, thereby preventing any noise from causing malfunction. Hysteresis width can be calculated as
follows:
Hysteresis width = R.D.COM x 20 ) A (Typ. value)
The optimum value depends on the motor, while 200 ꢁ to 300ꢁ is recommended.
13/16
4) Cylinder and output current slope setting capacitor (CSL1, CSL2)
Triangle wave is output from D.SL terminal 1 and 2 for normal rotation of the cylinder. Level 1 is output for Low-
level of the triangle wave. The level determined by cylinder rotating speed is output for High-level. Adjust the
capacitor of terminal D.SL1 and D.SL2 and the resistance of ISET terminal so that this High-level is approximately
1.8V. It can be set as follows:
Example: When normal rotation speed of cylinder is 9000 rpm, capacitor of terminal D.SL1 and D.SL2 0.047ꢂF and
resistance 18 k ꢁ are recommended.

5) Setting of drive signal frequency in cylinder startup
Drive signal frequency in cylinder startup can be controlled by changing the capacitor of D.DETECT terminal.
Adjust the optimum value, so that starting time is shortest on your motor. Drive signal frequency during startup
can be calculated as follows: Optimum value depends on motor, while 0.1 - 0.2 ꢂ F is recommended.

6) PCI/PCV terminal connecting capacitor (capstan/cylinder)
Capacitor connected to PCI and PCV terminal is used to compensate the phase of upper and lower saturation
prevention circuit and current feedback loop. When it is too large, the entire loop (including servo system), becomes
unstable. When it is too small, the output waveform oscillates. Recommended are 100pF for PCI terminal, 0.1 ꢂ F
for PCV terminal of cylinder, 0.1 ꢂ F for PCI terminal and 0.1 ꢂ F for PCV terminal of capstan.
7) DC/DC (capstan/cylinder)
When the output of VS terminal of capstan/cylinder is connected to the DC/DC converter, the motor voltage can be
controlled according to the output voltage waveform of the motor. When the DC/DC converter gain is low, the
maximum VM voltage cannot be output. The output current waveform is distorted, therefore adjust to an optimum
value.
8) RNF terminal
Connect a small resistor (0.33 ꢁ to 0.5 ꢁ) between RNF terminal and GND for detecting output current. Because
High current flows in this resistor, take precautious against high resistor wattage. The value of the torque command
gain versus this resistor (0.33 ꢁ), is described in the electrical characteristics. Note that this value also changes
when resistance changes.
9) Voltage rising circuit
This IC applies Nch DMOS on output stage, and incorporates a voltage boost current for the corresponding gate
voltage. When the capacitance value between CP1 terminal and CP2 terminal is low, the current capability of VG
terminal voltage is low. When the capacitance value between VG terminal and GND terminal is low, the ripple of
VG voltage becomes high. Recommended capacitance value between terminal CP1 and CP2 is 0.1 to 0.22 ꢂ F
and that between terminal VG and GND is 1 to 10 ꢂ F.

ʀOperation Notes
1) Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break
down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated
values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses.
2) Power supply lines
Design PCB layout pattern to provide low impedance GND and supply lines. To obtain a low noise ground and
supply line, separate the ground section and supply lines of the digital and analog blocks. Furthermore, for all power
supply terminals to ICs, connect a capacitor between the power supply and the GND terminal. When applying
electrolytic capacitors in the circuit, note that capacitance characteristic values are reduced at low temperatures.
3) GND potential
Ensure a minimum GND pin potential in all operating conditions. In addition, ensure that no pins other than the GND pin
carry a voltage less than or equal to the GND pin, including during actual transient phenomena. The voltage of the motor
output pin may, however, drop below the GND potential due to the BEMF voltage of the motor. Malfunctions or other
failures may result, depending on the operating conditions, environment, and individual characteristics of the motor.
Check that the IC has no operational problems.
4) Thermal Design
Use a proper thermal design that allows for a sufficient margin of the power dissipation (Pd) at actual operating conditions.
5) Pin short and mistake fitting
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if positive and ground power supply terminals are reversed. The IC may also be damaged if pins are
shorted together or are shorted to other circuit’s power lines.
6) Operation in a strong electromagnetic field
Use caution when using the IC in the presence of a strong magnetic field, as doing so may cause the IC to malfunction.
7) ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum ratings or ASO.
8) Thermal shutdown circuit
If the junction temperature (Tj) reaches 175°C (Typ.), the TSD circuit will operate, and the coil output circuit of the motor
will open. There is a temperature hysteresis of approximately 25°C (Typ.). The TSD circuit is designed only to shut off the
IC in order to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. The
performance of the IC’s characteristics is not guaranteed and it is recommended that the device is replaced after the TSD
is activated.
9) Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress.
Always discharge capacitors after each process or step. Always turn the IC's power supply off before connecting it to, or
removing it from a jig or fixture, during the inspection process. Ground the IC during assembly steps as an antistatic
measure. Use similar precaution when transporting and storing the IC.
10) Ground wiring patterns
If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern
from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the
wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay
attention not to cause fluctuations in the GND wiring pattern of external parts as well.
11) Capacitors connected between output and ground pins
If a large capacitance value is connected between the output and ground pins, and if the VCC falls to 0 V or becomes
shorted with the ground pin, the current stored in the capacitor may flow to the output pin. This can cause damage to the
IC. The capacitance value between the output and GND must be 100ꢂF or lower.
12) Regarding input pin of the IC
If no Vcc voltage is applied to the IC do not apply any voltage to the input pins. If a voltage higher, or as high as the Vcc, or
a voltage lower than, or as low as, the GND is applied, parasitic elements may result due to the structure of the IC. The
operation of parasitic elements can cause interference with circuit operation as well as IC malfunction and damage. Use
caution so that the IC is not used in a manner that will trigger the operation of parasitic elements.
13) Operating Precautions
Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to
verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits
may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow
for sufficient margins when determining circuit constants.
