500V / 600V High Voltage Three-phase Motor Driver ICs
SCM1200MF Series
Data sheet
Description
Package
The SCM1200MF series are high voltage three-phase
motor driver ICs in which transistors, pre-driver ICs
(MICs), and bootstrap circuits (diodes and resistors) are
highly integrated. These products can run on a
three-shunt current detection system and optimally
control the inverter systems of medium-capacity motors
that require universal input standards.
SCM (pin pitch: 1.27 mm, mold dimensions: 47 × 19 × 4.4 mm)
Features
Not to scale
● Each half-bridge circuit consists of a pre-driver IC
● In case of malfunction, all outputs shut down via three
FO pins connected together
● Built-in bootstrap diodes with current limmiting
resistors (22 Ω)
● CMOS compatible input (3.3 to 5 V)
● Pb free
● Isolation voltage: 2500 V for 1 min,
UL recognized component (File No.: E118037)
● Fault signal output at protection activation
● Protections include:
Undervoltage Lockout for power supply

Truth Table
Table 6-1 is a truth table that provides the logic level definitions of operation modes.
In the case where HIN and LIN signals in each phase are high at the same time, the simultaneous on-state prevention
function sets both the high-side and low-side transistors off.
After recovering from a UVLO_VCC condition, the high-side and low-side transistors resume switching according to
the input logic levels of the next HIN and LIN signals (level-triggered).
After recovering from a UVLO_VB condition, the high-side transistors resume switching at the next rising edge of an
HIN signal (edge-triggered).

Typical Applications
CR filters and Zener diodes should be added to your application as needed, so that you can: protect each pin against
surge voltages causing malfunctions; and avoid the IC being used under the conditions exceeding the absolute
maximum ratings, resulting in critical damage to itself. Then test all the pins thoroughly under actual operating
conditions to ensure that your application works flawlessly.

12. Functional Descriptions
All the characteristic values given in this section are
typical values, unless they are specified as minimum or
maximum.
For pin descriptions, this section employs a notation
system that denotes a pin name with the arbitrary letter
“x”, depending on context. The U, V, and W phases are
represented as the pin numbers 1, 2, and 3, respectively.
Thus, “(the) VBx pin” is used when referring to either of
the VB1, VB2, or VB3 pin. Also, when different pin
names are mentioned as a pair (e.g., “the VBx and HSx
pins”), they are meant to be the pins in the same phase.
12.1. Turning On and Off the IC
The procedures listed below provide recommended
startup and shutdown sequences.
To turn on the IC properly, do not apply any voltage
on the VBB, HINx, and LINx pins until the logic power
supply, VCC, has reached a stable state (VCC(ON) ≥ 12.5
V). It is required to charge bootstrap capacitors, CBOOT,
up to full capacity at startup (see Section 12.2.2).
To turn off the IC, set the HINx and LINx pins to
logic low (or “L”), and then decrease the VCCx pin
voltage.
12.2. Pin Descriptions
(1)
(2)
In Formula (1), let TL(OFF) be the maximum off-time
of the low-side transistor, measured in seconds, with the
charging time of CBOOT excluded.
Even during the high-side transistor is not on, voltage
on the bootstrap capacitor keeps decreasing due to
power dissipation in the IC. When the VBx pin voltage
decreases to VBS(OFF) or less, the high-side undervoltage
lockout (UVLO_VB) starts operating (see Section
12.3.3.1). Therefore, actual board testing should be done
thoroughly to validate that voltage across the VBx pin
maintains over 12.0 V (VBS > VBS(OFF)) during a
low-frequency operation such as a startup period.
As shown in Figure 12-1, in each phase, a bootstrap
diode, DBOOT, and a current-limiting resistor, RBOOT, are
placed in series between the VCCx and the VBx pins.
The charging time of CBOOT, tC, is given by Formula
(3):

where CBOOT is the optimized capacitance of the
bootstrap capacitor, and RBOOT is the resistance of the
current-limiting resistor (22 Ω ± 20 %).

serve as connection terminals to the three-phase motor.

12.2.2. VB1, VB2, and VB3
These are the inputs of the high-side floating power
supplies for the individual phases.
Voltages across the VBx and HSx pins should be
maintained within the recommended range (i.e., the
Logic Supply Voltage, VBS) given in Section 2.
In each phase, a bootstrap capacitor, CBOOT, should be
connected between the VBx and HSx pins.
For proper startup, turn on the low-side transistor first,
then charge the bootstrap capacitor, CBOOT, up to its
maximum capacity.
Satisfying the formulas below can provide optimal
capacitance for the bootstrap capacitors, CBOOT. Note
that whichever resulting value is larger should be chosen
in order to deal with capacitance tolerance and DC bias
characteristics.

Bootstrap circuit
Figure 12-2 shows an internal level-shifting circuit
that produces high-side output signals, HOx. A high-side
output signal, HOx, begins to respond when an input
signal, HINx, transits from low to high (rising edge) or
high to low (falling edge). And a signal triggered on a
rising edge is called “Set”, whereas a signal triggered on
a falling edge is called “Reset”. Either of these two
signals, Set or Reset, is then transmitted to the high-side
by the level-shifting circuit. Finally, the SR flip-flop
circuit feeds an output signal, Q (i.e., HOx).
Figure 12-3 is a timing diagram describing how noise
or other detrimental effects will improperly influence the

level-shifting process. When a sharp voltage drop, which
is affected by noise, between the VBx and HSx pins
(also denoted as “VBx–HSx” in the tables in previous
sections), occurs after the Set signal generation, the next
Reset signal cannot be sent to the SR flip-flop circuit.
And the state of the high-side output, HOx, stays logic
high (or “H”) because the SR flip-flop does not respond.
With the HOx state being held high, the next LINx
signal can still turn on the low-side transistor and cause
a simultaneously-on condition which may result in
critical damage to the IC.
To protect the VBx pin against such noise effect, add
a bootstrap capacitor, CBOOT, in each phase. CBOOT
should be placed near the IC and connected between the
VBx and HSx pins with a minimal length of traces. To
use an electrolytic capacitor, add a 0.01 µF to 0.1 µF
bypass capacitor, CP, in parallel near other functional
pins used for the same phase.

12.2.4. VCC1, VCC2, and VCC3
These are the logic supply pins for the built-in
pre-driver ICs. The VCC1, VCC2, and VCC3 pins must
be externally connected on a PCB because they are not
internally connected. To prevent malfunction induced by
supply ripples or other factors, put a 0.01 µF to 0.1 μF
ceramic capacitor, CVCC, near other functional pins used
for the same phase. To prevent damage caused by surge
voltages, put a 18 V to 20 V Zener diode, DZ, between
the VCCx and COMx pins.
Voltages to be applied between the VCCx and COMx
pins should be regulated within the recommended
operational range of VCC, given in Section 2.
12.2.5. COM1, COM2, and COM3
These are the logic ground pins for the built-in
pre-driver ICs. For proper control, each of them must be
connected to the corresponding ground pin. The COM1,
COM2, and COM3 pins should be connected externally
on a PCB because they are not internally connected.
Varying electric potential of ground can be a cause of
improper operations; therefore, each connection point of
these pins should be as close to the LSx pin as possible
but separated from the power ground. Moreover,
extreme care should be taken when wiring so that
currents from the power ground do not affect the COMx
pin. To reduce noise effects, connect these pins closely
to shunt resistors, RS, at a single-point ground (or, a star
ground) with traces of a minimal length (see Figure
12-4).

12.2.6. HIN1, HIN2, HIN3,
LIN1, LIN2, and LIN3
U1
These are the input pins of the internal motor drivers
for each phase. The HINx pin acts as a high-side
controller, whereas the LINx pin acts as a low-side
controller.
Figure 12-5 shows an internal circuit diagram of the
HINx or LINx pin.
This is a CMOS Schmitt trigger circuit with 22 kΩ
pull-down resistor and input logic is active high.
Input signals through the HINx–COMx and the
LINx–COMx pins in each phase should be set within the
ranges provided in Table 12-1, below. Note that dead
time setting must be done because the IC does not have
a dead time generator.
The higher PWM carrier frequency rises, the more
switching loss increases. Hence, the PWM carrier
frequency must be set so that operational case
temperatures and junction temperatures can have
sufficient margins in the absolute maximum ranges
specified in Section 1.
If the signals from the microcontroller become
unstable, the IC may result in malfunctions. To avoid
this event, control the outputs from the microcontroller
output line should not be high impedance.
Also, if the traces between the microcontroller and
both the HINx and LINx pins are too long, the traces
may be interfered by noise. Therefore, it is
recommended to add an additional filter or a pull-down
resistor near the the HINx or LINx pin as needed. (See
Figure 12-6.
Here are filter circuit constants for reference:
RIN1: 33 Ω to 100 Ω
RIN2: 1 kΩ to 10 kΩ
CIN: 100 pF to 1000 pF
Extra attention should be paid when adding RIN1 and
RIN2 to the traces. When they are connected each other,
the input voltage of the HINx and LINx pins becomes
slightly lower than the output voltage of the
microcontroller.

This is the input pin for the main supply voltage, i.e.,
the positive DC bus. All of the IGBT collectors of the
high-side are connected to this terminal.
Voltages between the VBB and COMx pins should be
set within the recommended range of the main supply
voltage, VDC, given in Section 2.
To absorb surge voltages, put a 0.01 μF to 0.1 μF
snubber capacitor, CS, near the VBB pin and an
electrolytic capacitor, CDC, with a minimal length of
PCB traces to the VBB pin.

12.2.8. LS1, LS2, and LS3
These are emitter pins of the low-side IGBTs. The
LS1, LS2, and LS3 pins are connected to the shunt
resistors, RS.
When connecting shunt resistors to these pins, such as
for current detection, trace lengths from the shunt
resistors to the IC should be as short as practicable.
Otherwise, malfunctioning may occur because a longer
circuit trace increases its inductance and thus increases
its susceptibility to improper operations.
For applications where long PCB traces are required,
add a fast recovery diode, DRS, between the LSx and
COMx pins in order to prevent the IC from
malfunctioning.

resistor, RFO, has a too small resistance value, the FOx
pin voltage at fault signal output becomes high due to
the on-resistance of a built-in MOSFET, QFO (Figure
12-8). Therefore, it is recommended to use a 1 kΩ to 22
kΩ pull-up resistor when the low-level input threshold
voltage of a microcontroller, VIL, is set to 1.0 V.
To suppress noise, add a filter capacitor, CFO, near the
IC with minimizing a trace length between the FOx and
COMx pins. Note that, however, this additional filtering
allows a delay time, tD(FO), to occur, as shown in Figure
12-9. The delay time, tD(FO), is a period of time which
starts when the IC receives a fault flag turning on the
internal MOSFET, QFO, and continues until when the
FOx pin reaches its threshold voltage (VIL) of 1.0 V or
below (put simply, until the time when the IC detects a
logic low state, “L”).
Figure 12-11 shows how the delay time, tD(FO), and the
noise filter capacitor, CFO, are related.
To avoid the repetition of Overcurrent Protection
(OCP) activations, the external microcontroller must
shut off any input signals to the IC within an OCP hold
time, tP, which occurs after the MOSFET (QFO) turn-on.
tP is 15 μs where minimum values of temperature
characteristics are taken into account. (For more details,
see Section 12.3.4.)
When VIL is set to 1.0 V, it is recommended to use a
0.001 μF to 0.01 μF noise filter capacitor, CFO, allowing
a sufficient margin to deal with variations in
characteristics.
Put a shunt resistor near
the IC with a minimum
length to the LSx pin.

in detail, respectively.
Figure 12-8 illustrates a schematic diagram of the
FOx pin and its peripheral circuit. Because of its
open-drain nature, each of the FOx pins should be tied
by a pull-up resistor, RFO, to external power supply
voltage, VFO. The external power supply voltage, VFO,
should range from 3.0 V to 5.5 V.

a built-in feature of the IC itself (see Section 12.3.4).

The FO1, FO2, and FO3 pins also can be the input

The voltages and pulse widths of the shutdown signals
to be applied between the FOx and COMx pins are listed
in Table 12-2.

12.3. Protection Functions
This section describes the various protection circuits
provided in the SCM1200MF series.
The protection circuits include: the undervoltage
lockout for power supply (UVLO), the simultaneous
on-state prevention function, the overcurrent protection
(OCP), and the thermal shutdown (TSD).
In case one or more of these protection circuits are
activated, the FO pin outputs a fault signal and the
external microcontroller stops all operations of the three
phases. The external microcontroller can also shut down
the IC operations by inputting a fault signal to the FOx
pin.
In the following function descriptions, “HOx” denotes
a gate input signal on the high-side transistor; whereas
“LOx” denotes a gate input signal on the low-side
transistor (See also the diagrams in Section 7.).
“VBx–HSx” refers to the voltages between the VBx pin
and HSx pin.

12.3.3. Undervoltage Lockout for Power
Supply (UVLO)
In case the gate-driving voltage of output transistors
decreases, the steady-state power dissipation of the
transistors increases and the IC may have permanent
damage, in the worst case. To prevent this event, the
SCM1200MF series has the undervoltage lockout
(UVLO) circuit for both of the high- and low-side power
supplies in each controller IC (MIC).
12.3.3.1. Undervoltage Lockout for
High-side Power Supply
(UVLO_VB)
Figure 12-13 shows operational waveforms of the
undervoltage lockout operation for high-side power
supply (i.e., UVLO_VB).
When the voltage between the VBx and HSx pins
(VBx–HSx) decreases to the Logic Operation Stop
Voltage of high-side (VBS(OFF), 11.0 V), the UVLO_VB
circuit in the corresponding phase activates and sets only
HOx signals to logic low. When the voltage between the
VBx and HSx pins increases to the Logic Operation
Start Voltage of high-side (VBS(ON), 11.5 V), the IC
releases the UVLO_VB condition. Then, the HOx
signals become logic high at the rising edge of the first
input command after the UVLO_VB release.
The FOx pin does not transmit any fault signals
during the UVLO_VB activation. In addition, each of
the VBx pins has an internal UVLO_VB filter of about 3
μs, in order to prevent noise-induced malfunctions.
12.3.3.2. Undervoltage Lockout for
Low-side Power Supply
(UVLO_VCC)
Figure 12-14 shows operational waveforms of the
undervoltage lockout operation for low-side power
supply (i.e., UVLO_VCC).
When the VCCx voltage decreases to the Logic
Operation Stop Voltage of low-side (VCC(OFF), 11.0 V),
the UVLO_VCC circuit in the corresponding phase
activates and sets both of HOx and LOx signals to logic
low.
When the VCCx voltage increases to the Logic
Operation Start Voltage of low-side (VCC(ON), 11.5 V),
the IC releases the UVLO_VCC condition. Then it
resumes transmitting HOx and LOx signals according to
the input commands on the HINx and LINx pins.
The FOx pin becomes logic low during the
UVLO_VCC activation.
In addition, each of the VCCx pins has an internal
UVLO_VCC filter of about 3 μs, in order to prevent
noise-induced malfunctions.

operation waveforms at OCP. When the OCPx pin
voltage increases to an Overcurrent Protection Threshold
Voltage, VTRIP, of 0.50 V, and then keeps in that
condition for an Overcurrent Protection Blanking Time,
tBK, of 1.65 μs or longer, the OCP circuit starts operating.
The enabled OCP circuit then shuts off the output
transistors and puts the FOx pin into a logic low state.
Even if the OCPx pin voltage falls below VTRIP, the IC
keeps in a logic low state for a fixed OCP hold time (tP)
of 26 μs (typ.). Then, the output transistors operate
according to input signals. Then, the output transistors
operate according to input signals.
The OCP circuits in the SCM1200MF series are used
for detecting abnormal conditions, such as an output
transistor shorted. Therefore, motor operation must be
stopped by the external microcontroller, which can
receive and handle fault signals from the IC. Otherwise,
your application will be more likely to cause short
circuit conditions repeatedly, thus the breakdown of the
output transistors.
Care should also be taken when using a 3-shunt
resistor system in your application. The IC running on
the 3-shunt resistor system only shuts off the output
transistor in the phase where an overcurrent condition
exists. And a fault signal is transmitted from the FOx pin
of the phase being under the overcurrent condition.
As already shown in Figure 12-12, if all of the FOx
pins being used makes a short circuit, a fault signal sent
from the corresponding phase can turn off the output
transistors of all phases (see Section 12.3.2).
length of traces.
Note that overcurrents are undetectable when one or
more of the U, V, and W pins are shorted to ground
(ground fault). In case either of these pins falls into a
state of ground fault, the transistors may be destroyed.

To place a shunt resistor in an actual application,
users must set:
● the shunt resistor to have the resistance specified as
shunt resistor, RS (see the recommended operating
condition table, Section 2);
● input voltages of the OCPx pin to keep their levels
within the range defined as the OCPx pin voltage,
VOCP (see the absolute maximum rating table, Section
1); and
● currents through output transistors to keep their levels
under the rated output current (pulsed), IOP (see the
absolute maximum rating table, Section 1).
Because high-frequency switching currents flow
through the shunt resistors, RS, choose a resistor that has
low inductance and allows high power dissipation.
When adding a CR filter (a pair of a filter resistor, RO
and a filter capacitor, CO) to the OCPx pin, the following
should be taken into account. Time constants of RO and
CO should be set to the values listed in Table 12-3.
The larger the time constant, the longer the time that
the OCPx pin voltage rises to VTRIP. And this may cause
permanent damage to the transistors. Consequently, the
time constants given here are determined in
consideration of the total delay time the IC will have.
The filter capacitor, CO, should also be placed near the
IC, between the OCPx and COMx pins with a minimal

12.3.5. Simultaneous On-state Prevention
When both of the HINx and LINx pins receive logic
high signals at once, the high- and low-side transistors
turn on at the same time, allowing overcurrents to pass
through. As a result, the switching transistors will be
destroyed. In order to protect this event, the
simultaneous on-state prevention circuit is built into
each of the controller ICs. Note that incorrect command
input and noise interference are also largely responsible
for such a simultaneous-on condition.
When logic high signals are asserted on the HINx and
LINx pins at once, as shown in Figure 12-17, this
function gets activated and turns the high- and low-side
transistors off.
Then, the FOx pin becomes a logic low state, and
sends fault signals during this function activation.
After the IC comes out of the simultaneous On-state,
"HOx" and "LOx" start responding in accordance with
HINx and LINx input commands again. In order to
prevent malfunctions due to noise, the simultaneous
on-state prevention circuitry has a filter of about 0.8 μs.
Note that the function does not have any of dead-time
programming circuits. Input signals to the HINx and
LIN pins must have proper dead times as defined in
Section 0).
When the temperature of the MIC increases to
TDH = 150 °C or more, the corresponding TSD circuit is
activated. When the temperature decreases to
TDL = 120 °C or less, the shut-down condition is
released and the transistors resume operating according
to input signals.
When the TSD circuits is being enabled, FOx pin
becomes logic low and transmits fault signals.
Note that junction temperatures of the output
transistors themselves are not monitored. Do not use the
TSD function as a prevention function against critical
damage to the output transistors.

The IC has thermal shutdown (TSD) circuits. Figure

In case of overheating, e.g., increased power
dissipation due to overload, or an ambient temperature
rise at the device, the IC shuts down the high- and
low-side output transistors.
Thermal detection is monitored by the MICs (see
Section 7).

13. Design Notes
This section also employs the terminal notation
system for pin names, described in the beginning of the
previous section.
13.1. PCB Pattern Layout
Figure 13-1 shows a schematic diagram of a motor
driver circuit. The motor driver circuit consists of
current paths carrying high frequencies and high
voltages, which also bring about negative influences on
IC operation, noise interference, and power dissipation.
Therefore, PCB trace layouts and component
placements play an important role in circuit designing.
Current loops which carry high frequencies and high
voltages should be as small and wide as you can, in
order to maintain a low-impedance state.
In addition, ground traces should be as wide and short
as possible so that radiated EMI levels can be reduced.

appropriate tightening within the range of screw
torque defined in Section 4.
● When mounting a heatsink, it is recommended to use
silicone greases.
If a thermally-conductive sheet or an electrically
insulating sheet is used, package cracks may be
occured due to creases at screw tightening. Therefore,
thorough evaluations should be conducted before
using these materials.
● When applying a silicon grease, there must be no
foreign substances between the IC and a heatsink.
Extreme care should be taken not to apply a silicon
grease onto any device pins as much as possible. The
following requirements must be met for proper grease
application:
 Grease thickness: 100 µm
 Heatsink flatness: ±100 µm
 When applying a silicon grease to a heatsink, it
should be applied within the area indicated in
Figure 13-2, below.

13.2. Heatsink Mounting Considerations
This section provides the guidelines for mounting a
heatsink, as follows:
● It is recommended to use a pair of a metric screw of
M3 and a plain washer of 7 mm (φ).
Use a torque screwdriver to tighten the screws.
Tighten the two screws firstly up to about 30% of the
maximum screw torque; then finally up to 100% of
the prescribed maximum screw torque. Perform
When measuring the breakdown voltage and/or
leakage current of the transistors incorporated in the IC,
the gate and emitter of each transistor should have the
same potential.
Moreover, care should be taken because the collectors
are all internally connected to the VBB pin.
The output (U, V, and W) pins are connected to the
emitters of the corresponding high-side transistors; and
the LSx pins are connected to the emitters of the
low-side transistors. The gates of the high-side
transistors are pulled down to the output (U, V, W) pins;
similarly, the gates of the low-side transistors are pulled
down to the COMx pins.
Note that the output, LS, and COMx pins must be
connected appropriately before measuring breakdown
voltage and/or leak current. Otherwise the switching
transistors may result in permanent damage.
The figures below are the schematic circuit diagrams
of a typical measurement circuit for breakdown voltage:

represented in these figures are open.
Before conducting a measurement, be sure to isolate
the ground of a measurement phase from those of other
two phases. Then, in each of the two separated phases,
connect the LSx and COMx pins each other at the same
potential, and leave them unused and floated.

Estimating Junction Temperatures
This section describes the procedures to: calculate
power losses in a switching transistor; and estimate
junction temperatures. Note that the following
descriptions are applicable to the SCM1200MF series,
which is controlled by a three-phase sine-wave PWM
driving strategy.
The total power losses in an IGBT can be obtained by
taking the sum of steady-state loss, PON, and switching
loss, PSW.
The following subsections contain the mathematical
procedures to calculate power losses in an IGBT and its
junction temperature.

The steady-state loss in an IGBT can be computed by
using the VCE(SAT) vs. IC curves, shown in Section 15.3.1.
As shown in Figure 14-1, the following linear
approximate equation can be obtained from the curves:
VCE(SAT) = α × IC + β. The slope and intercept of the
linear approximate equation are used in Formula (4).
Table 14-1 lists the reference slopes and intercepts of
the linear approximate equation at a half of output
current, 0 to 0.5 × IO.
The values calculated with the linear approximation
greatly differ at the point where IC is near zero. But in
dissipation calculation, the difference is regarded as an
error tolerance. Hence, the equation for the steady-state
loss, PON, is:
