Description of Blocks
1. Commutation Logic
When the hall frequency is about 1.4-Hz or less (e.g. when the motor starts up), the commutation mode is 120° square
wave drive with upper and lower switching (no lead angle). The controller monitors the hall frequency, and switches to
150° commutation drive when the hall frequency reaches or exceeds about 1.4-Hz over four consecutive cycles. Refer to
the timing charts in figures 13 and 14.
2. Duty Control
The switching duty can be controlled by forcing DC voltage with value from VSPMIN to VSPMAX to the VSP pin. When the
VSP voltage is higher than VSPTST, the controller forces PC pin voltage to ground (Testing mode, maximum duty and no
lead angle). The VSP pin is pulled down internally by a 200 kΩ resistor. Therefore, note the impedance when setting the
VSP voltage with a resistance voltage divider.
4. FG Signal Output
The number of FG output pulses can be switched in accordance with the number FGS No. of pulse
of poles and the rotational speed of the motor. The FG signal is output from the FG
pin. The 12-pulse signal is generated from the three hall signals (exclusive NOR), H 12
and the 4-pulse signal is the same as hall U signal. It is recommended to pull up L 4
FGS pin to VREG voltage when malfunctioning because of the noise.

The bootstrap is operated by the charge period and the discharge period being alternately repeated for bootstrap
capacitor (CB) as shown in the figure above. In a word, this operation is repeated while the output of an external
transistor is switching with synchronous rectification. Because the supply voltage of the floating driver is charged from the
VCC power supply to CB through prevention of backflow diode DX, it is approximately (VCC-1V). The resistance series
connection with DX has the impedance of approximately 200 Ω. Because the total gate charge is needed only by the
carrier frequency in the upper switching section of 150° commutation driving, please set it after confirming actual
application operation.

(Note 2) It works together with the fault operation, and returns after the release time synchronizing with the carrier frequency.
(Note 3) It returns to normal operation after 32 cycles of the carrier oscillation period.
Caution: 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 and the internal circuitry. 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.

Operational Notes
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.
5. 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. The absolute maximum rating of the Pd stated in this specification is when the IC
is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating, increase
the board size and copper area to prevent exceeding the Pd rating.
7. 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.

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

residue after soldering
[h] Use of the Products in places subject to dew condensation
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
