a) Stand-by mode
Stand-by operates independently with the VREF pin voltage. In stand-by mode, all internal circuits are turned off,
including the output power transistors. Motor output goes to high impedance. When the system is switched to
stand-by mode while the motor is running, the system enters an idling state because of the body diodes. However,
when the system switches to stand-by from any other mode (except the brake mode), the control logic remains in the
high state for at least 50µs before shutting down all circuits.
b) Forward mode
This operating mode is defined as the forward rotation of the motor when the OUT1 pin is high and OUT2 pin is low.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT1 to OUT2. To operate
in this mode, connect the VREF pin to the VCC pin.
c) Reverse mode
This operating mode is defined as the reverse rotation of the motor when the OUT1 pin is low and OUT2 pin is high.
When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT2 to OUT1. To operate
in this mode, connect the VREF pin to the VCC pin.
d) Brake mode
This operating mode is used to quickly stop the motor (short circuit brake). It differs from the stand-by mode because
the internal control circuit is operating in the brake mode. Please switch to stand-by mode (rather than the brake
mode) to save power and reduce consumption.

e) f) PWM control mode A
The rotational speed of the motor can be controlled by the duty cycle of the PWM signal fed to the FIN pin or the
RIN pin. In this mode, the high side output is fixed and the low side output is switching, corresponding to the input
signal. The state of the output toggles between "L" and "Hi-Z".
The frequency of the input PWM signal can be between 20kHz and 100kHz. The circuit may not operate properly for
PWM frequencies below 20kHz and above 100kHz. Note that control may not be attained by switching on duty at
frequencies lower than 20kHz, since the operation functions via the stand-by mode. To operate in this mode,
connect the VREF pin to the VCC pin. In addition, establish a current path for the recovery current from the motor,
by connecting a bypass capacitor (10µF or higher is recommended) between VCC and ground.

i) j) VREF control mode
The built-in VREF duty cycle conversion circuit provides a duty cycle corresponding to the voltage of the VREF pin
and the VCC voltage. The function offers the same level of control as the high voltage output setting function in
previous models. The duty cycle is calculated by the following equation.
DUTY ≈ VREF [V] / VCC [V]
For example, if VCC voltage is 24V and VREF pin voltage is 18V, the duty cycle is about 75 percent. However,
please note that the duty cycle might be limited by the range of the VREF pin voltage (Refer to the operating
conditions, shown on page 2). The PWM carrier frequency in this mode is 25kHz (nominal), and the switching
operation is the same as the PWM control modes. When operating in this mode, do not input a PWM signal to the
FIN and RIN pins. In addition, establish a current path for the recovery current from the motor, by connecting a
bypass capacitor (10µF or more is recommended) between VCC and ground.

2) Cross-conduction protection circuit
In the full bridge output stage, when the upper and lower transistors are turned on at the same time during high to low
or low to high transition, an inrush current flows from the power supply to ground, resulting to a loss. This circuit
eliminates the inrush current by providing a dead time (about 400ns, nominal) during the transition.
3) Output protection circuits
a) Under voltage lock out (UVLO) circuit
To ensure the lowest power supply voltage necessary to operate the controller, and to prevent under voltage
malfunctions, a UVLO circuit has been built into this driver. When the power supply voltage falls to 5.0V (nominal) or
below, the controller forces all driver outputs to high impedance. When the voltage rises to 5.5V (nominal) or above,
the UVLO circuit ends the lockout operation and returns the chip to normal operation.
b) Over voltage protection (OVP) circuit
When the power supply voltage exceeds 45V (nominal), the controller forces all driver outputs to high impedance.
The OVP circuit is released and its operation ends when the voltage drops back to 40V (nominal) or below. This
protection circuit does not work in the stand-by mode. Also, note that this circuit is supplementary, and thus if it is
asserted, the absolute maximum rating will have been exceeded. Therefore, do not continue to use the IC after this
circuit is activated, and do not operate the IC in an environment where activation of the circuit is assumed.

c) Thermal shutdown (TSD) circuit
The TSD circuit operates when the junction temperature of the driver exceeds the preset temperature (175℃
nominal). At this time, the controller forces all driver outputs to high impedance. Since thermal hysteresis is provided
in the TSD circuit, the chip returns to normal operation when the junction temperature falls below the preset
temperature (150℃ nominal). Thus, it is a self-resetting circuit.
The TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or
guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is
activated, and do not operate the IC in an environment where activation of the circuit is assumed.
d) Over current protection (OCP) circuit
To protect this driver IC from ground faults, power supply line faults and load short circuits, the OCP circuit monitors
the output current for the circuit’s monitoring time (10µs, nominal). When the protection circuit detects an over
current, the controller forces all driver outputs to high impedance during the off time (290µs, nominal). The IC returns
to normal operation after the off time period has elapsed (self-returning type). At the two channels type, this circuit
works independently for each channel.

Operational Notes
1) Absolute maximum ratings
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such
as adding a fuse, in case the IC is operated over the absolute maximum ratings.
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 IC’s power supply terminals.
3) Power supply lines
Design the PCB layout pattern to provide low impedance ground and 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.
4) Ground Voltage
The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no
pins are at a voltage below the ground pin at any time, even during transient condition.
5) Thermal consideration
Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in
actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).
Package Power dissipation
Power dissipation
: Pd (W)=(Tjmax－Ta)/θja
: Pc (W)=(Vcc－Vo)×Io+Vcc×Ib
Tjmax : Maximum junction temperature=150℃, Ta : Peripheral temperature[℃] ,
θja : Thermal resistance of package-ambience[℃/W], Pd : Package Power dissipation [W],
Pc : Power dissipation [W], Vcc : Input Voltage, Vo : Output Voltage, Io : Load, Ib : Bias Current
6) Short between pins and mounting errors
Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a
wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles
caught between the pins.
7) Operation under strong electromagnetic field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
8) 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).
9) Capacitor between output and GND
If a large capacitor is connected between the output pin and GND pin, current from the charged capacitor can flow into
the output pin and may destroy the IC when the VCC or VIN pin is shorted to ground or pulled down to 0V. Use a
capacitor smaller than 10uF between output and GND.
10) 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.
11) Switching noise
When the operation mode is in PWM control or VREF control, PWM switching noise may affect the control input pins
and cause IC malfunctions. In this case, insert a pull down resistor (10kꢀ is recommended) between each control input
pin and ground.

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.

Precaution on using ROHM Products
(Note 1)
1. If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment
,
aircraft/spacecraft, nuclear power controllers, 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 not designed 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
[b] the temperature or humidity exceeds those recommended by ROHM
[c] the Products are exposed to direct sunshine or condensation
[d] the Products are exposed to high Electrostatic
2. Even under ROHM recommended storage condition, solderability of products out of recommended storage time period
may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is
exceeding the recommended storage time period.
3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads
may occur due to excessive stress applied when dropping of a carton.
4. Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of
which storage time is exceeding the recommended storage time period.
