MOS INTEGRATED CIRCUIT
µPD168110
MICROSTEP DRIVER FOR DRIVING CAMERA LENS
DESCRIPTION
The µPD168110 is a monolithic 2-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. This product employs a P-channel
MOSFET on the high side of the output stage, eliminating a charge pump. As a result, the circuit current consumption
can be substantially reduced during operation.
This product is ideal for driving the motor of a digital still camera as it can switch over between two-phase excitation
driving and microstep driving, using a stepper motor.
FEATURES
O Two H bridge circuits employing power MOSFET
O Current feedback 64-step microstep driving and two-phase excitation driving selectable
O Low on-resistance: 2 Ω MAX.
O 3 V power supply
Minimum operating power supply voltage VDD = 2.7 V
O Under voltage lockout circuit
Shuts down internal circuitry at VDD = 1.7 V TYP.
O 24-pin TSSOP

FUNCTION DESCRIPTION
2-phase excitation driving mode
By allowing a current of 100% to flow into output ch1 and ch2 at the same time, a motor can be driven with the
larger torque.
The two-phase excitation driving mode and microstep driving mode are switched by the MODE pin. In the two-
phase excitation driving mode, the chopping pulse circuit does not operate.
Microstep driving of stepper motor
To position a stepper motor with high accuracy, the µPD168110 has a function to hold constant the current flowing
through the H bridge by a vector value and to stop one cycle in 64 steps. To realize the microstep driving mode, the
driver internally realizes the following functions.
• Detecting the current flowing into each channel as a voltage value by a sense resistor
• Synthesizing the dummy sine wave of the half-wave generated by the internal D/A and PWM oscillation wave for
chopping operation
• The driver stage performs PWM driving based on the result of comparing the detected voltage value and
synthesized waves.
The internal dummy sine wave is of 64 steps per cycle, so that the stepper motor can be driven in 64 steps. The
microstep driving mode and two-phase excitation driving mode are switched by an external pin.

Concept of microstep driving operation
MOB output
The MOB output pin outputs “L” if the current of ch1 or ch2 reaches 100% in the microstep output mode, or if the
current of ch 1 reaches +100%. In the two-phase excitation output mode, the MOB pin outputs “L” when the current of
ch1 and ch2 reaches +100%. The excitation position of the stepper motor can be checked by monitoring the MOB
output. The MOB output also indicates the stop position information in the stop mode to be explained below.
The MOB output goes into a Hi-Z state (output H level if pulled up) when OE = “L”.
Stop mode
If the stop mode is set by the STOP pin, the pulse is automatically output until MOB = “L” when CLK is input. If
MOB = “L” in the stop mode, the pulse is not output even when CLK is input, and the output holds the excitation
status.
To advance the pulse, release the stop mode and restore the normal mode.
9
Data Sheet S15840EJ2V0DS
µPD168110
Reset function
When RESET = “L”, initialization is executed and the output goes into a Hi-Z state. When RESET = “H”, excitation
is started with the current of ch1 at +100% and the current of ch2 at 0% (one-phase excitation position). To perform
two-phase excitation driving, excitation is started with the currents of ch1 and ch2 at +100% after the mode has been
set. Be sure to execute a reset operation after power application. MOB outputs “L” until the pulse is output when
RESET goes “L”.
Output enable (OE) pin
The pulse output can be forcibly stopped from an external source by using the OE pin. When OE = “L”, the output
is forcibly made to go into a Hi-Z state.
Standby function
The µPD168110 can enter the standby mode when the pulse is not output and when PS = “H” and
STOP = “H”. In the standby mode, as many internal circuits as possible are stopped so that the self current
consumption can be reduced. In the standby mode, the current consumption is 1 µA MAX. when external CLK input is
stopped. While CLK is being input, the current consumption is reduced to 300 µA MAX. by the current flowing into the
input buffer. The standby mode is released when PS = “L” and STOP = “L”.
Under voltage lockout circuit (UVLO)
This function is used to forcibly stop the operation of the IC to prevent malfunction of the circuits if VDD of the IC
drops during operation. Note that if the VDD voltage abruptly drops in the order of µs, this function may not operate.
VM pin current shutdown circuit
A circuit that prevents a current from flowing into the VM pin when VDD = 0 V is provided. Therefore, the current
flowing into the VM pin is cut off when VDD = 0 V.
A current of up to 3 µA flows into the VM pin when VDD is applied so that the voltages on the VDD and VM pins can
be monitored.

OPERATION DESCRIPTION
• Setting output current
The peak value of the output current (when current of ch 1 or ch 2 is 100%) is determined by the resistor RFB that
is connected to FB1 and FB2. This IC has an internal reference power supply VREF (500 mV TYP.) for comparing
current, and drives the stepper motor with the current value calculated by RFB and VREF as the peak output
current value.
Peak output current value IMAX (A) ≅ VREF (V) ÷ RFB (Ω) x Output detection ratio
• Pulse output
The motor is driven by inputting a pulse to the CLK pin. The motor advances by one pulse at the rising edge of
the CLK signal. When MODE = “H”, the motor is driven in the 64-microstep driving mode, and the driving current
of each step is determined based on the internal motor excitation position information and revolution direction.
When MODE = “L”, the two-phase excitation mode is selected, and the current direction (100% drive) of ch 1 and
ch 2 are switched each time a pulse has been input.
• Setting motor revolution direction
The revolution direction of the motor is set by CW. In the CW mode (CW = “L”), the current of ch2 is output, 90°
degrees in phase behind the current of ch1. In the CCW mode (CW = “H”), the current of ch2 is output, 90°
degrees in phase ahead of the current of ch1.

• Setting stop mode (valid only in microstep driving mode)
When STOP = “H”, the motor advances to the position of MOB output = “L”, and the output status is held.
The excitation status is not changed even when a pulse is input to CLK while MOB = “L” when STOP = “H”. The
pulse can be advanced when STOP = “L”.

• Power save mode (valid only in microstep driving mode)
When PS = “H” and STOP = “H”, the motor advances to the position of MOB output = “L” and then the output
goes to a Hi-Z state.
The internal circuitry is stopped as much as possible and the standby mode is set. The power save mode is
released when PS = “L” and STOP = “L”.

• Selecting two-phase excitation/microstep driving mode
The MODE pin can be used to select the two-phase excitation or microstep driving mode. When MODE = “H”,
the microstep driving mode is selected. When MODE = “L”, the two-phase excitation mode (both ch 1 and ch 2
are driven at +100% or –100%) is selected. The µPD168110 is initialized immediately after a RESET operation,
so excitation is started from the position at which the output current of ch 1 is 100% and the output current of ch
2 is 0% in the microstep driving mode, and from the position at which the output currents of both ch 1 and ch 2
are +100% in the two-phase excitation driving mode.
If the mode is changed from the microstep to the two-phase, the position of the microstep mode is retained until
CLK is input. When the first CLK is input, pulse output is started, the operation skips to the two-phase position of
the next quadrant, and driving is started.

The output function of MOB can be selected by MOBSEL. When MOBSEL = “L”, MOB is output at the position
where the current of ch1 is +100% and the current of ch2 is 0%. When MOBSEL = “H”, MOB is output at the
position where the current of ch1 or ch2 is 100%.

Cautions 1. The undervoltage lockout detection circuit (UVLO) operates at 1.7 V TYP. whereupon the
output goes into a Hi-Z state. Internal data such as the excitation position information is
reset. The UVLO circuit does not operate after reset.
2. A shutdown circuit that prevents a current from flowing into the VM pin when VDD = 0 V is
provided.
