Application Design Note
(a) The bypass capacitor connected must be more than the recommended constant value because there is a
possibility of the motor start-up failure etc. due to IC malfunction.
Substrate Design Note
(a) IC power (VCC), motor outputs (OUT1, 2), and motor ground lines are made as wide as possible.
(b) IC ground (GND) line is common with the application ground except motor ground (i.e. hall ground etc.), and
arranged near to (–) land.
(c) The bypass capacitor and/or Zener diode are placed near to VCC pin.
(d) H+ and H– lines are arranged side by side and made from the hall element to IC as short as possible,
because it is easy for the noise to influence the hall lines.

Functional Descriptions
1.
Variable Speed Operation
The rotational speed of the motor changes by the PWM duty of the motor outputs (OUT1 and OUT2 terminals).
However, it provides for the motor's output not by the rotational speed but by the duty in the BD61241FV, because
the rotational speed is not uniquely decided by the motor output duty.
The changeable speed operation is controlled by these two input terminals.
(1)
(2)
PWM Operation by Pulse Input in PWM Terminal
PWM Operation by DC Input in MIN Terminal
(Note) PWM frequency of output is 50kHz (Typ). Hence, input PWM frequency is not equal to PWM frequency of output.
(1)
PWM Operation by Pulse Input in PWM Terminal
The PWM signal from the controller can be input directly to IC in Figure 25. The output duty is controlled by
the input PWM duty (Figure 26). Refer to recommended operating conditions (P.3) and electrical
characteristics (P.4) for the input condition.
Internal power-supply voltage (INTERNAL REG; Typ 5.0V) is impressed when the PWM terminal is open, it
becomes 100% input of the duty and equivalent, and a full torque is driven. There must be a pull-down
resistance outside of IC to make it to torque 0 when the PWM terminal opens (However, only at the controller
of the complimentary output type.). Insert the protective resistance and capacitor for noise removal if
necessary.

Full torque (VPWM>2.5V) and zero torque (VPWM 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.
Figure 62. Example of Monolithic IC Structure
13. Ceramic Capacitor
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with
temperature and the decrease in nominal capacitance due to DC bias and others.
14. 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).
15. Thermal Shutdown (TSD) Circuit
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 will rise which will activate the TSD circuit that will turn OFF all output pins. When the junction
temperature 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.

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 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
