(Ex.) In case of setting 1 cycle = 10.67 µs, ta = 1.27 µs, brake1 = 0.13 µs, tb = 1.93 µs, brake2 = 7.07 µs.
osc[2:0]( = Basic cycle setting ) = 0x0 （ = Basic cycle = 66.67 ns）, and ta / brake1 / tb / brake2 setting below;
ta[7:0]
brake1[7:0]
tb[7:0]
= 0x13
= 0x03
= 0x1E
= 0x6B
= 19 count
= 3 count
= 30 count
= 107 count
→ ON section = 19 + 1 – 1 = 19 count
→ ON section = 2 count
→ ON section = 29 count
brake2[7:0]
→ ON section = 106 count

6) Setting method of VM voltage slope
The slope can be applied to the VM voltage by setting V1[7:0], V2[7:0], step1[2:0] and step2[4:0].
V1 and V2 are bits for setting VM voltage. The step1 and step2 are bits for setting VM slope.
VM voltage increase that it set it every 50 µs.
It is necessary to enlarge the setting of V2 more than V1.
LSB of each setting bits does not depend on the VCC voltage (LSB = 4.8 / 255 = 18.8 mV (Typ.)).

●Operational Notes
1) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings, such as the applied voltage (VCC) or operating temperature
range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or
open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when
using the IC at times where the absolute maximum ratings may be exceeded.
2) Storage temperature range (Tstq)
As long as the IC is kept within this range, there should be no problems in the IC’s performance. Conversely, extreme
temperature changes may result in poor IC performance, even if the changes are within the above range.
3) Power supply and wiring
Be sure to connect the power terminals outside the IC. Do not leave them open. Because a return current is generated
by a counter electromotive force of the motor, take necessary measures such as putting a Capacitor between the
power source and the ground as a passageway for the regenerative current. Be sure to connect a Capacitor of proper
capacitance (0.1 to 10 µF) between the power source and the ground at the foot of the IC, and ensure that there is no
problem in properties of electrolytic Capacitors such as decrease in capacitance at low temperatures. When the
connected power source does not have enough current absorbing capability, there is a possibility that the voltage of the
power source line increases by the regenerative current exceeds the absolute maximum rating of this product and the
peripheral circuits.
Therefore, be sure to take physical safety measures such as putting a zener diode for a voltage clamp between the
power source the ground.
4) Ground terminal and wiring
The potential at GND terminal should be made the lowest under any operating conditions. Ensure that there are no
terminals where the potentials are below the potential at GND terminal, including the transient phenomena.
Also prevent the voltage variation of the ground wiring patterns of external components. Use short and thick power
source and ground wirings to ensure low impedance.
5) Thermal design
Use a proper thermal design that allows for a sufficient margin of the power dissipation at actual operating conditions.
6) Pin short and wrong direction assembly of the device
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.
7) Avoiding strong magnetic field
Malfunction may occur if the IC is used around a strong magnetic field.
8) ASO
Ensure that the output transistors of the motor driver are not driven under excess conditions of the absolute maximum
ratings and ASO.
9) TSD circuit
This IC incorporates a TSD circuit. If the temperature of the chip reaches the below temperature, the motor coil output
will be opened. The TSD circuit is designed only to shut off the IC to prevent runaway thermal operation. It is not
designed to protect the IC or to guarantee its operation. Do not continue to use the IC after use of the TSD feature or
use the IC in an environment where the its assumed that the TSD feature will be used.

Precaution on using ROHM Products
1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you
intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific
Applications.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radiation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification

Precaution for Electrostatic
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper
caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be
applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron,
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control).
Precaution for Storage / Transportation
1. Product performance and soldered connections may deteriorate if the Products are stored in the places where:
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2
