DSC Motor Driver
Features
• An actuator driver for single focus digital camera is implemented on a single chip.
(1) Supports a constant voltage for the AF H-bridge×2 : a stepping motor (STM) ×1.
- Constant voltage drive.
- Enables 1-phase, 1-2 phase and 2-phase excitation.
- VC1 and VC2 allow the constant voltage for each channel to be set independently.
(2) Supports a constant current for the shutter H-bridge×1 : a voice coil motor (VCM) ×1.
- Constant current drive.
- A fast charge/discharge circuit allows for stabilization of response speed for the continuous drive mode.
- Allows offsetting of the constant current rising waveform with an external CR.
(The external CR is not required when an offset is not performed.)
→ Prevent current rising variation of coil caused by supply voltage fluctuation.
- Implements regenerative brake logic.
(3) Supports a constant voltage for the iris H-bridge×1 : a voice coil motor (VCM) ×1.
- Constant voltage drive.
- VC4 allows the independent constant voltage to be set.

Application Design Notes
(1) Constant-voltage setting for OUT1 to OUT6
“H” output voltage for OUT1 and OUT2 can be set by the VC1 pin input voltage.
The setting formula is as follows:
(OUT1/2 output voltage) = (VC1 input voltage) ×5.27
Correspondingly, OUT3 and OUT4 can be set by VC2, and OUT5 and OUT6 can be set by VC3.
The setting formula is as follows:
(OUT3/4 output voltage) = (VC2 input voltage) ×5.27
(OUT5/6 output voltage) = (VC3 input voltage) ×5.27
In addition, if the right side setting of the above formula exceeds the supply voltage (VB),
the output voltage is saturated.
(2) Output pin oscillation prevention capacitor for OUT1 to OUT6 constant-voltage control.
For constant-voltage control of OUT1 to OUT6, a capacitor must be placed between OUT pins in order to prevent
oscillation.
Test capacitor values between 0.01µF to 0.1µF and choose a value that does not cause output oscillation problems.
However, for the saturated drive, no oscillation prevention capacitor is necessary.
(3) Constant-current setting between OUT7 and OUT8
Constant-current setting between OUT7 and OUT8 depends on the IC pin input voltage and IM pin connection
resistance (current detection resistor).
As shown in the block diagram, the output current is controlled so that the IC pin input voltage can be equal to the
voltage generated on the current detection resistor which is connected between IM and GND.
The formula for output current is as follows:
(Output current) = (IC input pin voltage) ÷ (current detection resistance)
In addition, since the constant-current control block is connected to PGND inside the IC, when the voltage is
supplied to the IC pin with partial resistance, GND side of the resistor must be connected to PGND.
(4) Fast charge/discharge circuit for the FC pin
In order to support high speed shutter control (sequential shutter), a built-in fast charge/fast discharge circuit is
implemented in the shutter control block (OUT7, OUT8).

VCC is high. (Without IC pin external capacitor)
VCC is low. (Without IC pin external capacitor)
Coil current
IC pin discharging
Rising offset coil current
Shutter “Close” operating
ILB01669
The rising waveform of the coil current can be offset by having the external CR network give a slope to the rising
waveform of the voltage input to the IC pin and setting a greater coil time constant to make the slope more
gradual. This ensures stable shutter operation under severe power voltage fluctuations.
Note : When offsetting the rising waveform of the coil current using the IC pin, assume the VB1 voltage that
could be obtained in the absence of the capacitor to the IC pin as the supposed minimum voltage and
observe and confirm the rising waveform of the coil current that flows at that voltage, then determine the
capacitance of the capacitor so as to yield a time constant value that is greater than the one that could
produce the waveform generated at the supposed minimum voltage.
The rising waveform offsetting capacitor is unnecessary if the power voltage supplied is stable or in similar cases
in which the rising waveform offsetting function is not required.
(6) FC pin phase compensation capacitor
The capacitor connected to the FC pin is used for phase compensation of constant-current control between OUT9
and OUT10.
Test capacitor values between 0.0015µF to 0.033µF and choose a value that does not cause output oscillation
problems.
(In particular, when a large-inductance coil is used, it is necessary to provide a margin to a capacity value.)
Moreover, since the constant-current control block is connected to PGND inside the IC, GND side of the FC pin
capacitor must be connected to PGND.
(Cautions for FC pin capacitor setting)
For the capacitor value setting, set the value by which the output does not oscillate, observing an output voltage
waveform.
In circuit, the FC pin is connected to the output part of the constant-current control amplifier, and an output
transistor drives because the potential of the FC pin rises.
That is, since the initial state of the FC pin influences the output-drive timing, the potential of the FC pin is
discharged (fast discharge circuit) inside the IC to a certain level before the shutter is ON, and the potential of the
FC pin is charged (fast charge circuit) inside the IC to a certain level when a shutter is ON, so that the state of the
FC pin during shutter driving can always be constant on this IC. This allows constant input/output delay time.
However, since the time involved in charge/discharge in the above-mentioned circuit will be long if the capacitor
value setting is too large, the amount of variation in charge/discharge delay time will increase with the variation
of capacitor value (absolute value variation and temperature characteristic).
Moreover, as another negative effect of setting a large value to the capacitor, it is considered that the rising
inclination of coil current is moderate. Although the rising inclination of coil current originally depends on L
component of the coil, if a large value is set to a capacitor and the capacitor time constant increases, the rising
inclination of coil current depends on the value of the capacitor.
For the reasons mentioned above, especially in the applications in which a high-speed shutter drive is required,
both the value by which output does not oscillate and as small a value as possible (0.0015µF to 0.033µF) must be
set to a capacitor which is connected to the FC pin.

(7) Shutter drive “Regeneration” mode
The “Regeneration” (MD1/MD2/MD3/IN1/IN2 = L/L/L/H/H) in shutter mode is used to slow the coil current
decay. This mode makes coil current regenerative (Slow-Decay) within the output H-bridge by switching from
“Close” (MD1/MD2/MD3/IN1/IN2 = L/L/L/L/H). (Refer to the following figure.)
(1) “Close” (MD1/2/3/IN1/2 = L/L/L/L/H)
OUT8
(2) “Regeneration” (MD1/2/3/IN1/2 = L/L/L/H/H)
OUT7
OUT8
OUT7
ILB01670
When shutter control is switched from “Stand-by” to “Close” (“Open”), the current rises to the target constantcurrent value from the state of output current 0 (zero). However, the output of the constant-current control
amplifier inside the IC is in the full drive state during the above-mentioned “Regeneration” state. Therefore, when
it is switched from “Regeneration” to “Close” (“Open”), the current falls to the target constant-current value from
the state of full drive output.
For that reason, to switch the shutter drive to “Close” (“Open”) from “Regeneration” by constant-current control,
it must be switched to “Stand-by” once before switching to “Close” (“Open”).
The example of drive sequence is shown in the figure below.

not guarantees of the performance, characteristics, and functions of the described products as mounted
in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an
independent device, the customer should always evaluate and test devices mounted in the customer's
products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO Semiconductor products (including technical data,services) described
or contained herein are controlled under any of applicable local export control laws and regulations, such
