Control and Operation  
1. OUTPUT MODE CONTROL AND OPERATION  
Control and operation of each output mode is described as follows:  
When INFWD is “HIGH” and INREV is “LOW”, the output is at normal rotation mode. In normal rotation mode, current  
flows from OUT+ to OUT-. When both INFWD and INREV are “HIGH”, the output is at brake mode. In brake mode,  
the top-side transistor is OFF to stop the supply of motor drive current while the bottom-side transistor is ON to absorb  
the reverse EMF of motor and apply brake to the motor. When both INFWD and INREV are “LOW, OUT+ and OUT-  
become high-impedance and the motor stops.  
2. OUTPUT VOLTAGE CONTROL  
Controlling the output voltage can vary the voltage applied to the motor and thus control motor speed. The output HIGH  
voltage can be controlled (gain 6dB Typ), using the voltage applied to the CONT terminal. The output voltage never  
exceeds the power supply voltage even if the voltage applied to CONT terminal exceeds (VCC Max).

Operational Notes  
1.  
2.  
Reverse Connection of Power Supply  
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when  
connecting the power supply, such as mounting an external diode between the power supply and the ICs power  
supply pins.  
Power Supply Lines  
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the  
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog  
block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and  
aging on the capacitance value when using electrolytic capacitors.  
3.  
Ground Voltage  
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.  
However, pins that drive inductive loads (e.g. motor driver outputs, DC-DC converter outputs) may inevitably go  
below ground due to back EMF or electromotive force. In such cases, the user should make sure that such voltages  
going below ground will not cause the IC and the system to malfunction by examining carefully all relevant factors  
and conditions such as motor characteristics, supply voltage, operating frequency and PCB wiring to name a few.  
4.  
5.  
Ground Wiring Pattern  
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but  
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal  
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations  
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.  
Thermal Consideration  
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in  
deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size  
and copper area to prevent exceeding the Pd rating.  
6.  
7.  
Recommended Operating Conditions  
These conditions represent a range within which the expected characteristics of the IC can be approximately  
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.  
Inrush Current  
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may  
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power  
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,  
and routing of connections.  
8.  
9.  
Operation Under Strong Electromagnetic Field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.  
Testing on Application Boards  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may  
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply  
should always be turned off completely before connecting or removing it from the test setup during the inspection  
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during  
transport and storage.  
10. Inter-pin Short and Mounting Errors  
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in  
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.  
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment)  
and unintentional solder bridge deposited in between pins during assembly to name a few.  
11. Unused Input Pins  
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and  
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small  
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and  
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the  
power supply or ground line.

Operational Notes continued  
12. Regarding the Input Pin of the IC  
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them  
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a  
parasitic diode or transistor. For example (refer to figure below):  
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.  
When GND > Pin B, the P-N junction operates as a parasitic transistor.  
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual  
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to  
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should  
be avoided.

13. Area of Safe Operation (ASO)  
Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe  
Operation (ASO).  
14. Thermal Shutdown Circuit(TSD)  
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always  
be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction  
temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below  
the TSD threshold, the circuits are automatically restored to normal operation.  
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no  
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from  
heat damage.

15. Capacitor Across Output and GND  
In the event a large capacitor is connected across output and GND, when VCC and IN are short-circuited with 0V or  
GND for some reason, the charge stored in the capacitor flows into the output and may destroy the IC. Use a  
capacitor smaller than 0.1 µF between output and GND.

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 depending on ambient temperature. When used in sealed area, confirm that it is the use in  
the range that does not exceed the maximum junction 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 on a surface-mount products, the flow soldering method must  
be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products,  
please consult with the ROHM representative in advance.  
For details, please refer to ROHM Mounting specification
