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.

Substrate design note
a) Motor power and ground lines are made as fat as possible.
b) IC power line is made as fat as possible.
c) IC ground line is common with the application ground except motor ground (i.e. hall ground etc.), and arranged
near to (-) land.
d) The bypass capacitors (VCC side and VM side) are arrangement near to VCC terminal and FETs, respectively.
e) H+ and H- lines are arranged side by side and made from the hall element to IC as shorter as possible,
because it is easy for the noise to influence the hall lines.

Functional descriptions
1) Variable speed operation
Rotating speed changes by PWM duty on the high side outputs (A1H, A2H terminals). PWM operation enables,
a) By DC voltage input in TH terminal, and MIN terminal
b) By pulse input in MIN terminal
a) PWM operation by DC input
As shown in Figure 31, to change high side output ON duty, DC voltage input from TH terminal is compared with
triangle wave produced by the OSC circuit. MIN terminal is for setting the minimum rotating speed. ON duty is
determined by either TH terminal voltage or MIN terminal voltage, whichever is lower.
OSC voltage > TH voltage (MIN voltage): high side output is ON
OSC voltage < TH voltage (MIN voltage): high side output is OFF

Figure 34. DC input operation timing chart
Dividing resistance of the internal regulator (equal to Typ 5.0V REF terminal) generates OSC high level (Typ
2.5V) and OSC low level (Typ 1.0V) voltage, and the ratio of those voltages is designed to be hard to fluctuate.
When the input voltage at TH terminal is constant, effect by fluctuation of OSC H/L voltage is large. However, by
setting that an application of REF voltage generates input voltage via TH, application can be made hard to be
affected by voltage fluctuation of triangle wave. For an application that requires strict precision, determine a
value with sufficient margin after full consideration of external constant is taken.
Protection against thermistor coming off
When the thermistor becomes an opening (the TH voltage is more than the REF voltage) as a protection
function in the DC input application that uses the thermistor like Figure 33, it doesn't depend on the MIN
voltage and it sets by the maximum rotation speed.
Setting of output oscillating frequency at DC voltage input
Frequency (Fosc) in which the high side outputs are operated PWM by DC voltage input is set according to
capacity value (Cosc) of the capacitor connected with OSC terminal.
FOSC[Hz] = (|IDOSC[A] x ICOSC[A]|) / {COSC[F] x (|IDOSC[A]| + |ICOSC[A]|) x (VOSCH[V] - VOSCL[V])}
(ex.) The frequency when output PWM operates becomes about 28kHz when assuming that Cosc is 470pF.
FOSC[Hz] = {|40[µA] x (-40[µA])|} / {470[pF] x (|40[µA]| + |-40[µA]|) x (2.5[V] - 1.0[V])}
= 28369[Hz]

2) Current limit
The current limit circuit turns off the output, when the current that flows to the motor coil is detected exceeding a set
value. The current value that current limit operates is determined by internal setting voltage and voltage of CS terminal.
In Figure 39, Io is the current flowed to the motor coil, RNF is the resistance detected the current, and PR is the power
consumption of RNF. When RNF=0.1[Ω], the current limit setting voltage (VCL) is 150mV,
Io[A] = VCL[V] / RNF[Ω]
= 150[mV] / 0.1[Ω]
= 1.5[A]
PR[W] = VCL[V] x Io[A]
= 150[mV] x 1.5[A]
= 0.225[W]
Be shorted CS terminal to GND, when the current limit
function is not used.
RCS and CCS consist of the low-pass filter for smoothing
RNF voltage.
Share and assume the ground of CCS to be the small
signal ground line with the GND pin of IC for the
malfunction prevention of a current limit. Separate with
the motor large current ground line with which RNF is
connected. Soft start capacitor CSS described later is
similar. (Refer to P.10 substrate design note c))

3) Soft start
Soft start is a function to gradually raise a driving torque at the time of motor start.
Be effective against reducing undesired sound and inrush current.
The soft start time is set by the charge to the capacitor connected with the terminal SS.
If motor output current (IO) and SS time (TSS) are decided, the value of capacitor (CSS) that sets a soft start can be
calculated by the following expressions because SS charge current (ISS) is 120nA.
CSS[F] = (ISS[A] x TSS[s]) / (IO[A] x RNF[Ω])
(ex.) When assuming that TSS = 0.47[s], IO = 1.2[A], and RNF = 0.1[Ω],
CSS[F] = (120[nA] x 0.47[s]) / (1.2[A] x 0.1[Ω])
= 0.47 x 10-6[F]

4) Quick start
When torque off logic is input by the control signal over fixed time (1.0ms), the lock protection function disables. And
the motor could restart quickly at the timing of control signal is input.
The lock protection function doesn’t work in an input frequency that is slower than 1kHz when assuming high level
duty = 100% of the MIN input signal. Input signal frequency is faster than 2kHz.

Adjust the value of hall element bias resistor R1 in Figure 44 so that the input voltage of a hall amplifier is input in "Hall
Input Voltage" including signal amplitude.
In order to detect rotation of a motor, the amplitude of hall signal more than "Hall Input Hysteresis Voltage" is required.
In consideration of PWM soft switching to mention later, input hall signal more than ±100mV at least.
Reducing the noise of hall signal
Vcc noise or the like depending on the wiring pattern of board may affect Hall element. In this case, place a
capacitor like C1 in Figure 44. In addition, when wiring from the hall element output to IC hall input is long, noise
may be loaded on wiring. In this case, place a capacitor like C2 in Figure 44.

6) PWM soft switching
The PWM soft switching section is set to the timing before and after the change of the hall signal. Be effective against
reducing undesired sound. Adjusting the amplitude of the hall signal can change the length of the PWM soft switching
section. The PWM soft switching section becomes wide if the amplitude of the hall signal is reduced, and the gradient
of the output current becomes smooth. However, when a soft switching is applied too much, torque shortage might be
caused. Input hall signal more than ±100mV at least.
The PWM soft switching function operates in the DC input application and the pulse input application.

7) Lock protection and automatic restart
Motor rotation is detected by hall signal period. IC detects motor rotation is stop when the period becomes longer than
the time set up at the internal counter, and IC turns off the output. Lock detection ON time (tON) and lock detection OFF
time (tOFF) are set by the digital counter based on internal oscillator. Therefore the ratio of ON/OFF time is always
constant. Timing chart is shown in Figure 46.

(ex.) At R1=1kΩ, PMOS transistor gate-source voltage VGSP can be shown below,
VGSP = R1×IH

R2 is used to suppress the power consumption of IC.
At power supply = 24V, the power consumption PM1 of upside output transistor M1 is
PM1 = { VM - (R1 + R2)×IH }×IH
= 144mW (at R1 = 1kΩ, R2 = 0Ω)
= 72mW (at R1 = 1kΩ, R2 = 0.5kΩ)
Useless power consumption in the upside output is suppressed by appropriately setting R2, and a permissible loss of the package
can be used effectively in lower output.
High voltage application
It is possible to correspond to 24V and 48V power supply by using the application circuit that is set not to exceed
the absolute maximum rating of Vcc, A1H to A2L, and AL terminal.

Thermal Derating Curve
Thermal derating curve indicates power that can be consumed by IC with reference to ambient temperature. Power that
can be consumed by IC begins to attenuate at certain ambient temperature. This gradient is determined by thermal
resistance θja.
Thermal resistance θja depends on chip size, power consumption, package ambient temperature, packaging condition,
wind velocity, etc., even when the same package is used. Thermal derating curve indicates a reference value measured
at a specified condition. Figure 53 shows a thermal derating curve.

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. 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.
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 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.
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.
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.

Operational Notes – continued
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 54. 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. 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.
