µPD168112
SERIAL CONTROL H-BRIDGE DRIVER FOR CAMERA LENS DRIVING
DESCRIPTION
The µPD168112 is a monolithic 6-channel H-bridge driver that consists of a CMOS controller and a MOS output
stage.
Compared with existing drivers that use bipolar transistors, this H-bridge driver can lower the current
consumption and voltage loss at the output stage thanks to employment of a MOS process. This product employs a
P-channel MOSFET on the high side of the output stage, eliminating the need for a charge pump, so that the circuit
current consumption can be substantially reduced during operation.
In the µPD168112 driving a stepper motor, DC motor, or coil can be selected by serial control, making this product
ideal for driving the motor of a digital still camera.
FEATURES

PIN FUNCTIONS
Pin Name
RESET
Detailed Pin Function
Initializes the internal circuitry of the IC. The output goes into a Hi-Z state and the registers are initialized. When a
stepper motor is driven, driving is started with phase A at +100% and phase B at 0%.
CLK
Inputs CLK from an external source for generating CLK that serves as a reference of the duty factor of a DC motor
or pulse cycle of a stepper motor.
CLKB
Outputs the signal input from CLK via the oscillator.
LATCH
Command input enable signal. Equivalent to chip select signal from a microcontroller.
SCLK
CLK signal for inputting a command. When data is transmitted, this signal is transmitted in synchronization with the
data. The contents of SDATA are read as data at the rising edge of SCLK.
SDATA
Command data input signal. Initialization is performed at addresses 0 and 1, and the contents of addresses 2 to 5
specify how the motor is to be driven.
VD
Pin that inputs a sync signal. The driver that drives a stepper motor outputs signals after wait time (set by address
1) has elapsed after VD has risen. The output timing is always constant if the VD signal is periodically input, even if
the timing of serial input changes. The driver starts outputting signals at the falling edge of the LATCH signal, not in
synchronization with VD, when a DC motor or a constant current is driven.
COSC
Pin that connects a capacitor to a triangular wave generator that drives a constant current. Connect a capacitor of
100 to 330 pF between this pin and GND.
OSC
Pin that connects a capacitor to a triangular wave generator that drives a stepper motor or a DC motor. Connect a
capacitor of 100 to 330 pF between this pin and GND.
RSEN
Connects a detector resistor to the constant-current detector.

VD must rise before LATCH rises (200 ns MIN.). VD must fall before LATCH falls (200 ns MIN.). In addition to the
operations shown above, an operation in which the VD signal overlaps the LATCH signal is incorrect.
If data related to a stepper motor (addresses 3−1 to 3−4) is input during the wait time, the previous data is ignored.
If data related to a DC motor coil (addresses 4 and 5) is input during the wait time, all the data is valid.

FUNCTIONAL DESCRIPTION
Serial Control
All information for driving the motor is processed by serial data from the CPU. The following parameters can be set
by commands.
- Wait value for setting timing when a stepper motor is driven
- 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 8-bit data. For the configuration of
the data and details of commands, refer to SERIAL INTERFACE SPECIFICATIONS on page 12.
2-phase Excitation Mode
By allowing a current of ±100% to flow into output phases A and B, the motor can be driven with a large torque. The
motor can be stopped in electrical cycle angle units of 90°. The two-phase excitation mode or 1-2 phase excitation
mode is selected by a command.
1-2 Phase Excitation Mode
By allowing a current of ±100% to flow into either output phase A or B and a current of ±70% to flow into the other
phase, the motor can be positioned with an accuracy higher than that in the two-phase excitation mode. The motor
can be stopped in electrical cycle angle units of 45°.
The two-phase excitation mode or 1-2 phase excitation mode is selected by a command.
Reset Function
An initialization operation is performed and all the internal data is cleared to 0 when RESET = low level. The output
remains in the Hi-Z state. When RESET = high level, commands can be input. Be sure to perform a reset operation
after power application. When RESET = low level, 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.
Power Application Sequence
This IC has a logic power supply (VDD) pin and an output power supply (VM) pin.
To turn on power, turn on VDD and then VM.
To turn off power, turn off VM with VDD on, and then turn off VDD.
(VDD and VM can also be turned on/off at the same time.)
Data Sheet S15866EJ1V0DS
11
µPD168112
SERIAL INTERFACE SPECIFICATIONS
The internal data is determined by inputting 8-bit serial data synchronized with serial clock CLK while LATCH = high
level, and then lowering LATCH. Serial data is input from the LSB (D0) to the MSB (D7).
SDATA: Data is loaded to the internal circuitry at the rising edge of SCLK when LATCH = high level.
LATCH: Inputting SDATA is prohibited when LATCH is low level. Inputting SDATA is enabled when it is high
level. The internal data is determined at the negative transition of LATCH (high level → low level).
Because this IC uses the external CLK, OSCIN, to generate the internal timing, the set values vary depending on the
frequency of OSCIN. An example where OSCIN = 5 MHz is given below. To input a frequency other than 5 MHz to
OSCIN, use the following expression. This applies to the serial registers marked
in SERIAL REGISTER DETAILS
on page 16 and 19.
Time: Set value = Setting example x (5/OSCIN [MHz] )
Frequency: Set value = Setting example x (OSCIN [MHz] /5)
Data Configuration
Data is configured of 8 bits.
Addresses are set in the order of command input. Six types of addresses, 0 to 5, are used.

LATCH
Data of one motor can be input in accordance with the motor driving data specifications that are set while LATCH =
high level. The input data is loaded in 8-bit units when SCLK = low level → high level after LATCH = low level → high
level, and the data is determined when LATCH = high level → low level.
Addresses 0 and 1 are used to perform initialization such as drive output settings. Turning on/off the motor and the
number of pulses are set by addresses 2 to 5. Once initialization has been performed, therefore, the motor can be
controlled simply by transmitting the drive data of addresses 2 to 5.
The stepper motor operates in synchronization with the VD signal. To update data, be sure to input the VD signal
(for details, refer to COMMAND INPUT TIMING CHART on page 8). When only the VD signal is input, the previous
status is retained and the output does not change.

SERIAL DATA INPUT SEQUENCE
The µPD168112 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 and 1 after power application and initialization.
(2) Input addresses 3, 4, and 5, depending on the type of motor to be driven.
(3) Input address 2 to specify the motor to be driven.
(4) Only addresses 3 to 5 and 2 have to be input subsequently to specify driving.
To perform an initialization operation such as selecting the motor, initialize the internal registers by using the
RESET pin.

• Wait value
When the stepper motor is to be controlled, counting is started from the rising of the VD 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 stepper
motor can be driven at a predetermined timing if the VD 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 32 to 2016 µs with a resolution of 32 µs using data D2 to D7.

• Output current value
Data of D3 to D7 selects 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/RSEN 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 operating frequency of the output is the
frequency oscillation by the oscillator connected to COSC (100 kHz TYP.).
Example: Where RSEN = 2 kΩ for constant-current driving at 100 mA
Set voltage value = 100 (mA) x 2 (kΩ) /1000
= 200 (mV)

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
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 once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build 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 bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.
