Description of Block(s)
(1) Regulator Output Terminal (VREG)
This is the terminal regulated 5V (Typ). Please set the capacitors of 0.1µF to 1µF. If using VREG for the bias power
supply for HALL elements, please don’t exceed the ratings of VREG current.
The rating for the max RPM〔%〕
(2) Controlling Rotation Speed Input Terminal (DCIN)
Rotation Speed can be controlled by inputting DC signal into DCIN, by changing the PWM duty of driver output. If
VCC is used for controlling the rotation speed, please set DCIN is VREG. When DCIN≤1V (Typ), all of the driver
outputs are controlled to “L”.

DCIN〔V〕
Figure 4. DCIN voltage vs rotation speed
The voltage of DCIN is input into the LOGIC circuit through the A/D inside IC. It sets the duty and makes the signals
of driver outputs demanding DCIN voltage. A/D samples DCIN voltage repeatedly and update the set point. The set
point is updated when it changes over ±1LSB from the previous point and when the next set point is in ±1LSB of
itself three times.(The typical time is 1ms(Typ)). Only the setting point of initial value is updated by the first sampling.
The A/D has 8 bit digital value and the power supply is VREG. 1LSB is about 19.5mV (5V/256,8bit). If VREG
fluctuates, the rotation speed fluctuates, too. So please stabilize VREG. It is better that DCIN is inputted the voltage
divider of VREG.

(3) Soft Start / Soft Stop Input Terminal (SSB)
The circuit of Soft Start and Soft Stop (SS mode) is built in to save the start/stop current. Soft Start and Soft Stop
mode is set by inputting VSSBH (Please see the table of Electrical Characteristics shown P.10). When SSB is VSSBL,
only CL circuit save the start and stop current. Please don’t change SSB terminal voltage during operating because
of the incorrect operation. SSB terminal is pulled up to VREG by the Resistors of 100kΩ±40kΩ. With regard to the
bias current, please see the table of Electrical Characteristics shown P.10.

(4) HALL Input (HALL: HUP, HUN, HVP, HVN, HWP, HWN)
HUP, HUN, HVP, HVN, HWP, HWN is the input terminal of HALL comparator in IC. The hysteresis voltage
(±15mV(Typ)), please see the table of Electrical Characteristics shown P.10) is set in HALL comparator to prevent
the incorrect operation by the noise. Please set the bias current of HALL elements over the minimum input voltage
(VHALLMIN, please see the table of Electrical Characteristics shown P.10) Also please set the ceramic capacitors about
1000pF to 0.01uF between the input of HALL comparator. As HALL comparator has the range of In-phase Input Voltage
(VHALLCM, please see the table of Electrical Characteristics shown P.10), please set the bias current of HALL
elements in VHALLCM. All of the driver outputs are Hi-Z when all of the outputs of HALL comparator (HU, HV, and HW)
are ”H” or “L”. In addition, if one of the outputs of HALL comparator keeps “H” or “L” on a certain time, all of the driver
outputs are Hi-Z, too. “a certain time” shows the period which the other outputs counted to 32 times of
positive/negative edge, after one of the outputs of HALL comparator is fixed “H” or “L”. This circuit is automatic
restarted if the HALL signals are correct after 5s.
Please pay attention to the positon of HALL elements for fear that the efficiency and the silence characteristic
become worse.

(5) FG Output Terminal (FGO)
3FG signal which is synthesize from the HALL signals is output from FGO. Please set FGO pulled up by the
resistors about 10kΩ to 100kΩ because FGO is the terminal of open-drain. Please pay attention not to exceed the
voltage rating and current rating of FGO because of the destruction of IC.
(6) Power Supply Terminal (VCC)
Please make VCC line low impedance (thick and short) because the Motor current flows. VCC might be changed
considerably by MOTOR BEMF and PWM switching, so please place the bypass capacitors as near as possible
between VCC and GND terminal. When the Motor generates large current or big BEMF, please add the value of
capacitors. Also, please set the ceramic capacitors about 0.01µF to 1µF to decrease the impedance of power supply
broadband. Please pay attention not to exceed the rating for a moment. Also, the device against ESD exists on VCC
terminal, so if the serge voltage over the rating, this ESD device operates and so IC may destroy. Please don’t
exceed the rating. It is so useful to add the Zener diode whose breakdown voltage is slightly lower than the rating. In
addition, if the voltage input in reverse, IC may destroy because of the ESD device between VCC and GND.
(7) Ground Terminal (GND)
Please make GND line as thick and short as possible to decrease the switching noise and stabilize the reference
voltage inside IC and please set GND the lowest voltage for a moment. Also, please design that GND of IC should
not have the common impedance in PCB.
(8) Driver Output Terminal (U, V, W)
Please pay attention about the following points in using driver output.
Wiring of U, V, and W should be thick and short (low impedance) because the motor current flows.
IC might destroy because the diodes against ESD operates when the serge pulse signal or the voltage over
the rating input into the terminals. Please don’t exceed the rating.
When the driver outputs change considerably toward positive and negative (for ex. BEMF voltage is so big), IC
operates abnormally or destroys. In the above case, please add the Schottky diode to the driver output terminal.
(9)
Resistor Connected Terminal for Detecting Output Current (RNF)
Please insert resistor for detecting current 0.18Ω to 0.5Ω between RNF and GND. Please pay attention that the
2
power consumption of resistor for detecting output current (multiply IOUT by R[W]) doesn’t be exceeded the rating of
the resistor. Because the Motor current flows to GND through RNF resistor, RNF line should be low impedance and
doesn’t have the common impedance of the other GND line. If RNF voltage exceeds the rating, IC might malfunction
or be destroyed, so please don’t exceed the rating. When RNF terminal is shorted to GND, large current flows due to
a lack of normal current limit operation. Please pay attention that OCP or TSD might operate in that case. Similarly, if
RNF terminal is OPEN, output current might not flow, and it causes malfunction.
(10) Comparator Input Terminal for Detecting Output Current (RCL)
RCL terminal (the terminal that the input of the current detect comparator) exists individually in order to avoid the
deterioration of current detect accuracy by wire impedance inside IC of RNF terminal. Therefore, when operating
current limit, please be sure to connect RNF terminal and RCL terminal. Moreover, it is possible to reduce the
deterioration of current detect accuracy that is caused by the impedance of board pattern between RNF terminal and
resistor for detecting current, to connect wiring from RCL terminal most adjacent to resistor for detecting current.
Please design the PCB pattern considering wiring that is less influenced by noise. Additionally, when RCL terminal is
shorted to GND, IC can’t operate normally and so the large current might flow. Please pay attention that OCP or TSD
might operate in that case.
(11) TEST terminal(TEST1,TEST2)
TEST terminal is for the shipping inspection. Please short to GND at normally use.

(12) Sequence of control signal
It is recommended to input the signal into LPE after VCC. (If LPE is input before VCC, IC operates correctly. However
in the case of LPE is “H” or “M”, please pay attention that Motor can’t be started if the Motor rotation can’t be
detected in the setting time (Please see P.10). IC has the priority between the control signals and the protection
signals. Please see the following table.

Protection Circuit
(1) Current Limit Circuit(CL circuit)
To change from the output current to the voltage by the resistor between RNF and GND and to input the signal into
RCL work as Current Limit (CL circuit). CL has the mask time to avoid the false detection because of the spike noise
when the output turns ON. Current limit doesn’t work in the mask time that RCL become over 0.2V (Typ). In the case
of SSB is “H”, all of the driver outputs turn “L” and it returns by itself after a certain time (1µs(Typ)). In the case of
SSB is “L”, the Motor torque is saved, after RCL voltage is under 0.2V (Typ), it turns to the normal operation. In both
of case the mask time of CL operation is 0.6µs (Typ).
(2) Thermal Shut Down Circuit(TSD Circuit)
TSD(Thermal Shut Down: TSD) operates when the chip temperature is over(175°C(Typ)) and all of the driver
outputs turn to Hi-Z. TSD circuit has the hysteresis (25°C (Typ)) so if the chip temperature is down, it operates
normally. The purpose of the TSD circuit is to protect driver IC from thermal breakdown. The temperature is over the
rating when TSD operates. Thus, it must have sufficient margin against TSD, and please don’t use continuously by
TSD as a precondition.
(3) Over Current Protection Circuit (OCP Circuit)
OCP (Over Current Protection: OCP) circuit prevent from the destruction of shorted between the output terminals
and VCC/GND shorted. The outputs are latched to Hi-Z when the output current exceeds the current rating and
reaches the OCP current. OCP can be reset by UVLO. It must have sufficient margin against OCP and please pay
attention not to use continuously by OCP as a precondition because the output current exceeds the current rating
when OCP operates. Also when the outputs shorted to GND or shorted between the outputs, the steep wave of VCC
or VREG occurs, finally OCP operation might be reset. So please consider fully.
(4) Under Voltage Lock Out Circuit (UVLO Circuit)
UVLO (Under Voltage Lock Out: UVLO) circuit prevent the false operation from under voltage. When VCC declines
to VUVL (6V (Typ)), all of the outputs turn to Hi-Z. UVLO circuit has hysteresis (1V (Typ)), so when VCC reaches more
than VUVH (7V (Typ)), it operates normally. Also when VREG is under 4V (Typ), UVLO operates.
(5) Over Voltage Lock Out Circuit(OVLO circuit)
Over voltage lock out circuit (Over Voltage Lock Out: OVLO) is built in for the purpose to save the lifted voltage at
the rotation speed down. All of the driver outputs turn “L” if LPE is “H” or “L” and VCC is over VOVH2 (31V (Typ)), if LPE
is “M” and VCC is over VOVH1 (15V (Typ)). OVLO circuit has the hysteresis. In the case of VOVH2, it operates normally
under VOVL2 (30.5V (Typ)). In the case of VOVH1, it operates normally under VOVL1 (15V (Typ)).
(6) Motor Lock Protection Circuit (MLP Circuit)
Motor lock protection circuit (Motor Lock Protection: MLP) is built in. Enable/Disable of MLP and OVLO threshold
can be set by LPE terminal. All of the driver outputs are Hi-Z when the outputs of HALL comparator keep “H” or “L”
during 1.1s (Typ) at LPE is "H" or "M". It restarts after 5s (Typ) if the outputs of HALL comparator change as the
normal operation. When LPE is "L", MLP circuit does not work. LPE terminal is pulled up by VREG through a
resistance of 100kΩ±40kΩ.

Operational Notes
1.
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 pins.
2.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. 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.
4.
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.
5.
Thermal Consideration
Should by any chance the maximum junction temperature 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 maximum junction temperature rating.
6.
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.
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.
8.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9.
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.

Operational Notes – continued
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.
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.
Figure 9. 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 the maximum junction temperature rating are all
within the Area of Safe Operation (ASO).

Operational Notes – continued
15. 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 maximum junction temperature 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.
16. Over Current Protection Circuit (OCP)
This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This
protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should
not be used in applications characterized by continuous operation or transitioning of the protection circuit.
17. Disturbance light
In a device where a portion of silicon is exposed to light such as in a WL-CSP, IC characteristics may be affected due
to photoelectric effect. For this reason, it is recommended to come up with countermeasures that will prevent the chip
from being exposed to light.
