µ PD168113
SERIAL CONTROL 7-CHANNEL H-BRIDGE DRIVER
DESCRIPTION
The µ PD168113 is a serial control 7-channel H-bridge driver that consists of a CMOS controller and a MOS output
stage. It can reduce the current consumption and the voltage loss at the output stage compared with a conventional
driver using bipolar transistors, thanks to employment of a MOS process. The µ PD168113 can drive various motor
coils by controlling the serial, so that the number of signal lines necessary for controlling the motor can be decreased.
The package is a 56-pin WQFN that helps reduce the mounting area and height.
The µ PD168113 can be used to drive two stepping motors, or two DC motors and one coil.

5. FUNCTIONAL DEPLOYMENT
5.1 Serial Control
All information for driving the motor is processed by serial data from the CPU. The following parameters can be set
by commands.
• Control of DC motor driving and output duty
• Control during constant-current driving and current setting
• Wait value for setting timing during stepping motor driving
• Motor current, motor revolution direction, and output excitation mode
• Pulse cycle, and number of pulses
Each command is assigned an address. Each data can be updated by inputting 16-bit data. For the configuration of
the data and details of commands, refer to 9. SERIAL INTERFACE SPECIFICATIONS.
5.2 Reset Function
An initialization operation is performed and all the internal data is cleared to 0 when RESETB = L. The output
remains in the Hi-Z state.
When RESETB = H, commands can be input.
Once it sets the address 0 to address 2 for an initialization setting, they carry out latch operation inside, and prohibit
overwriting. In order that initialization operation is performed again, the reset operation is needed.
Be sure to perform a reset operation after turning on power supply. When RESETB = L, the internal circuitry is
stopped whenever possible, so that the self current consumption can be reduced. When input of the external CLK is
stopped, the current consumption can be lowered to 1 µA MAX.
Immediately after release of reset, excitation is started from the position where the current of ch1 is 100% and the
current of ch2 is 0%, in the micro step drive mode and 1-2 phase excitation drive mode. In the 2-phase excitation
drive mode, excitation is started from the position where the currents of ch1 and ch2 are 100%.
Remark L: Low level, H: High level, Hi-Z: High impedance
5.3 Current Detection Resistor Connection (FB) Pin
The current detection resistor is connected when current driving is necessary.
For example: When micro step driving, when solenoid driving.
The current that flows into the output is {set voltage value/FB pin resistance x 1000}.
Example)
Where the set voltage value is 200 mV, FB = 2 kΩ
Output current value = 200 (mV) /2 (kΩ) x 1000
= 100 (mA)
Therefore, the load is driven at a constant current of 100 mA.
The set voltage value is a value that can be set by serial control.
Data Sheet S16423EJ2V0DS

µ PD168113
5.4 Undervoltage Lockout (UVLO) Circuit
This function is to forcibly stop the operation of the IC to prevent malfunctioning if VDD drops.
If VDD drops abruptly in the order of several µs, this function may not operate.
5.5 Overheat Protection (TSD) Circuit
This function is to forcibly stop the operation of the IC to protect it from destruction due to overheating if the chip
temperature of the IC rises.
The overheat protection circuit operates when the chip temperature rises to 150°C or more. When overheat is
detected, all the circuits are stopped. When reset is performed or when UVLO is detected, the overheat protection
circuit does not operate.
5.6 Power Up Sequence
This IC has a circuit that prevents current from flowing into the VM pin when VDD = 0 V. Therefore, the current that
flows into the VM pin is cut off when VDD = 0 V.
Because the VDD pin voltage and VM pin voltage are monitored, a current of 3 µA MAX. flows into the VM pin when
VDD is applied.

µ PD168113
6. COMMAND INPUT TIMING CHART
This IC can drive a stepping motor, DC motor, and solenoid by serial control if serial control is set during initialization.
If direct input is set, this IC can drive the load by an input/output PWM control method.
With the serial control setting, two or more motors can be simultaneously controlled by commands.
Be sure to execute initialization (addresses 0 to 2) immediately after power application and immediately after reset.
After initialization, the motors can be controlled simply by inputting driving data (addresses 3 to F).
To execute initialization again from the start, the RESET pin must be made high and data of addresses 0 to 2 must
be input.

7. SERIAL DATA INPUT SEQUENCE
The µ PD168113 can control driving of two or more motors with only a few CPU signals by using a serial data input
method. The serial data is input as follows.
(1) Input addresses 0 to 2 after power up and initialization.
(2) Depending on the type of the motor set, input the necessary data of addresses 3 to F (two or more addresses may
be input).
(3) When performing the driving setting, only the necessary data of addresses 3 to F has to be input because the
previous data is retained.
Only the output related to the input address will change.
To perform an initialization operation such as selecting the motor, initialize the internal registers by using the
RESETB pin.

8. NOTES ON TRANSMITTING DATA
• The first input data is loaded when SCLK changes from L to H after LATCH has changed from L to H.
Data is transmitted in 16-bit units, and is determined when LATCH changes from H to L. Invalid data of less than
16-bit is discarded.
• Data of different addresses can be input successively while LATCH = H.
• The access time can be shortened by updating only the necessary data after initialization has been performed.
If an address is not input, the previous value of that address is held as the data.
Examples)
DC motor and constant current: The ON/OFF state is held.
Stepping motor: The excitation position is held if the excitation state is in ON.
• If the same address is input more than one while LATCH = H, the last input data is valid.
• If invalid data and correct data are input while LATCH = H, only the correct data is valid.
• If only LATCH is input, the data is not updated, and the driver holds the current status.
• If a command related to stepping motors (addresses 8 to F) is input during the “wait period” that lasts from input of
the preceding data to the start of counting, the data is ignored. A command related to the DC motor and coil
(addresses 3 to 7) is valid during the synchronization period.
• Data that is input when RESETB = L is ignored.
Data Sheet S16423EJ2V0DS

µ PD168113
9. SERIAL INTERFACE SPECIFICATIONS
The internal data is determined by inputting 16-bit serial data SDATA synchronized with serial clock SCLK, and
making LATCH = L. Serial data is input from the LSB (D0) to the MSB (Df).
SDATA: When LATCH = H, data is loaded to the internal circuitry at the rising edge of SCLK, and latch
operation performed a the falling of SCLK
LATCH: Inputting SDATA is prohibited when LATCH is L. Inputting SDATA is enabled when it is H. The
internal data is determined when LATCH changes from H to L.
Because this IC generates the internal timing via the external CLK (OSCIN) its set values depend upon the
frequency of CLK.
An example where CLK = 5 MHz is given below. To input a frequency other than 5 MHz to CLK, use the following
expression. Items related to the serial register are marked
.
Time: Set value = Setting example x (5/CLK [MHz] )
Frequency: Set value = Setting example x (CLK [MHz] /5)
<Data configuration>
16-bit data consists of address: 4-bit and data: 12-bit.
Four bits (Dc, Dd, De and Df) are used to set an address. Sixteen types of addresses 0 to F can be used.
Twelve bits (D0 to Db) are used to set data.

11.1.1 Wait value
When the stepping motor is to be controlled, counting is started from the falling of the LATCH signal and the motor is
excited when the count value reaches 0. Even if transmission of serial data is delayed by the wait value, the stepping
motor can be driven at a predetermined timing if the LATCH signal is periodically input.
Note that the wait value must not be set to 0. The wait time can be set in a range of 64 to 2048 µs with a resolution
of 32 µs using data.

D6 = 1: Constant-current driving mode that can be set only by serial mode.
When D6 = 0, ch3 and ch4 have functions equivalent to ch1 and ch2, and can be used to drive a stepping motor.
When D6 = 1, ch3 and ch4 are independently used for constant-current driving. However, because ch3 and ch4
internally share the same driving power supply, these channels must be supplied from the same source.

A chopping mode is employed for the output to drive the motor on a constant current.
The chopping frequency that is the reference of the output can be changed with data, so that the PWM output does
not interfere with the other signals.
The chopping frequency can be set in a range of 40 to 250 kHz by the data of D0 to D5.
The set chopping frequency is used for output when executing stepping motor and constant-current driving.

11.2.2 Pulse output function selection when EXT output
If D6 is set, the function which acts as the monitor of the output state of the driving pulse by the EXT pin can be
selected.
When D6 = 0,
EXT1: Output pulse synchronization mode of the micro step output 1
EXT2: Output pulse synchronization mode of the micro step output 2
When D6 = 1,
EXT1: Mode with output time of micro step output 1 fixed to H
EXT2: Mode with output time of micro step output 2 fixed to H
The output synchronization mode is duty 50% TYP. in accordance with the pulse frequency setting.
To count the number of pulses, count the rising edges.
11.2.3 Restrictions in pulse output synchronization mode
(1) Output is not guaranteed if the pulse period is 2 µs (Db to D0: 000000000001).
(2) Output is equivalent to the H time during steady-state driving (equivalent to pulse period setting) while an
acceleration/deceleration operation is performed.
(3) If the multiplication factor of the number of pulses is set to other than 1, the set number of pulses (address 5 x m)
is output.
11.2.4 Restrictions in mode in which output time is fixed to H
The output falls in synchronization with the falling of the pulse that is to be output at the same timing in the pulse
output synchronization mode.
When the last pulse is output , therefore, it rises earlier than the period of the pulse cycle (50% of pulse cycle or less)

11.2.6 MOB output position setting (when micro step driving or 1-2 phase excitation driving)
The MOB output timing position can be selected by D8. It becomes effective when the micro step driving mode or
the 1-2 phase excitation driving mode selected.
D8 = 0: MOB is output at the one-phase excitation position (where the current of ch1 or ch2 is 100%) .
D8 = 1: MOB is output at the two-phase excitation position (where the currents of ch1 and ch2 are the same) .
Selection of MOB output (D7) is made in accordance with the setting of D8.
When D8 = 1, no signal is output from the MOB pin immediately after reset. In addition, MOB1 and MOB2 cannot be
set individually.

11.4.3 Output current value setting
Data of D3 to D7 sets the current value for constant-current control. These bits select the internal voltage that serves
as a reference with a resolution of 20 mV. The current that flows to the output is { set voltage value/FB x 1000 } .
A voltage lower than 100 mV is fixed to 100 mV, and a voltage exceeding 500 mV is fixed to 500 mV. Therefore, the
reference voltage can be set in a range of 100 to 500 mV. The operation frequency of the output is the frequency
oscillation by the oscillator connected to COSC (100 kHz TYP.).
Example)
The set output current is calculated as follows where FB = 2 kΩ for constant-current driving at 100 mA.
Set voltage value = 100 (mA) x 2 (kΩ) /1000 = 200 (mV) → (D7......D3) = (01010)

When D6 = 1, the motor advances to the position of MOB1 output = L, and the output status is held.
The set number of pulses is held even in the stop mode.
Because the motor is driven regardless of the set number of pulses, however, the position information of the motor
must be taken into consideration when a command is set to resume driving.

Caution Inputting data is prohibited while the stop mode is set (MOB1 reaches L). Do not update the data.
No pulse is output if the stop mode is set while MOB1 = L
In addition, MOB2 is output in the case of address C.
11.6.4 Output enable setting
D7 = 1: The motor can be driven. To drive the motor, be sure to set this bit to 1.
D7 = 0: The output goes into a Hi-Z state, regardless of the other settings.
If D7 is changed from 0 to 1, the internal information is held and therefore the excitation position is recorded.
Therefore, excitation is started from the position where D7 is cleared to 0.

11.6.5 Driving mode selection 0 and driving mode selection 1
D8 and D9 can be used to select driving mode of two-phase excitation, 1-2 phase excitation and micro step.
D8 = 0: The micro step driving mode is selected.
D8 = 1, D9 = 0: The two-phase excitation driving mode is selected.
D8 = 1, D9 = 1: The 1-2 phase excitation driving mode is selected.
Immediately after rest, The micro step driving mode is selected.
When changing the driving mode from micro step to two-phase excitation or 1-2 phase excitation, note the following
points.
<If the number of pulses is set to 0>
The stop position when the constant current is changed may differ depending on Da, which selects a constant
current in the two-phase or 1-2 phase excitation mode.
When Da = 0, the execution jumps to the two-phase or 1-2 phase position on the quadrant at the excitation position
after completion of wait, and the motor is excited at a duty factor of 100%. When Da = 1, the stop position is excited
and held.
<If pulse output is started by command setting to set a number of pulses of 1 or more>
At the first pulse, the operation skips to the two-phase excitation position or the1-2 phase excitation position of the
next quadrant and driving is started.
If the two-phase excitation driving mode is changed while the motor is stopped at the one-phase excitation position, it
is judged that the position is included in the quadrant in the CW direction, and motor operates.

11.6.6 Constant-current changing when two-phase excitation/1-2 phase excitation
Da is used to select whether the motor is driven at an output duty of 100% (maximum torque operation) or under
constant-current control when the two-phase excitation driving or the 1-2 phase excitation driving is selected.
When Da = 0, the motor is driven at an output duty of 100%. It is excited in two-phase or 1-2 phase and driven at the
maximum torque regardless of the current setting.
When Da = 1, the motor is excited in two-phase or 1-2 phase at the motor current setting. The output current value
is controlled to be the same value as the driving current at the phase A = phase B position (position of step θ 8) in the
micro step driving mode.

11.7 Address 9
This address is used to set parameters for acceleration/deceleration control, the pulse multiplication factor.
By setting the parameters for acceleration/deceleration control, the pulse cycle can be gradually changed while the
motor is accelerated or decelerated, so that step out of the motor can prevent.
By setting the pulse number multiplication factor to a value other than 1, the number of pulses can be extended in
combination with the number of pulses set by address B. If the default value is not changed, the motor is driven
without being accelerated or decelerated, and under the condition that the pulse number multiplication factor is 1.

If all of the twelve-bit is 0, no pulse is output and the driving status is maintained.
The pulse period indicates the time per step regardless of the driving mode (micro step, 1-2 phase excitation, or 2phase excitation). Therefore, the number of revolutions of the motor differs depending on the driving mode, even if

Set the number of pulses to drive the motor. D0 to Db can be set a pulse in a range of 0 to 4095 pulses.
If the pulse number multiplication factor is set to a value other than 1 at address 9, the number of pulses set here is
multiplied by the set multiplication factor (m).
The number of pulses is internally multiplied by (m) and then counted. If it is set to output pulses to EXT1 (EXT2 in
the case of address F), the number of counts output is the set value itself (0 to 4095 x m) .
The number of pulses indicates the number of pulses per pulse period regardless of the driving mode (micro step, 12 phase excitation, or 2-phase excitation). Therefore, the number of revolutions of the motor differs depending on the

13. FUNCTION OPERATION TABLE
The table below shows the input/output logic when ch5 to ch7 are set in the external control mode by initialization.
With ch7, an H-bridge current can be controlled by an external resistor for constant-current driving (output chopping
operation by PWM driving).
The external control mode is invalid immediately after reset and before an address is set.
Therefore, address setting is necessary even when the external control mode is used.
13.1 Serial Setting Contents of ch5 and ch6
Even when the external control mode is selected, the contents of the set output duty factor of ch5 (address 5) and
ch6 (address 6) are reflected. As the output duty factor of the output stage, therefore, the logical product of an
external control signal and the serial command setting is output. For the setting method by a command, refer to 11.5
Address 5 and Address 6.
13.2 Setting of ch7
ch7 is used for constant-current driving with a resistor connected to the FB pin. The current that serves as a
reference is set by a serial command. Therefore, set the current of ch7 (address 7) even when the external control
mode is selected.
For the setting method by a command, refer to 11.4 Address 3, Address 4, and Address 7.

NOTES FOR CMOS DEVICES
1
VOLTAGE APPLICATION WAVEFORM AT INPUT PIN
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the
CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may
malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,
and also in the transition period when the input level passes through the area between VIL (MAX) and
VIH (MIN).
2
HANDLING OF UNUSED INPUT PINS
Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is
possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND
via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must
be judged separately for each device and according to related specifications governing the device.
3
PRECAUTION AGAINST ESD
A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as
much as possible, and quickly dissipate it when it has occurred.
Environmental control must be
adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that
easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static
container, static shielding bag or conductive material. All test and measurement tools including work
benches and floors should be grounded.
The operator should be grounded using a wrist strap.
Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for
PW boards with mounted semiconductor devices.
4
STATUS BEFORE INITIALIZATION
Power-on does not necessarily define the initial status of a MOS device. Immediately after the power
source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does
not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the
reset signal is received. A reset operation must be executed immediately after power-on for devices
with reset functions.
