NOTES FOR CMOS DEVICES
1
VOLTAGE APPLICATION WAVEFORM AT INPUT PIN
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the
CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may
malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed,
and also in the transition period when the input level passes through the area between VIL (MAX) and
VIH (MIN).
2
HANDLING OF UNUSED INPUT PINS
Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is
possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND
via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must
be judged separately for each device and according to related specifications governing the device.
3
PRECAUTION AGAINST ESD
A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as
much as possible, and quickly dissipate it when it has occurred. Environmental control must be
adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that
easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static
container, static shielding bag or conductive material. All test and measurement tools including work
benches and floors should be grounded. The operator should be grounded using a wrist strap.
Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for
PW boards with mounted semiconductor devices.
4
STATUS BEFORE INITIALIZATION
Power-on does not necessarily define the initial status of a MOS device. Immediately after the power
source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does
not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the
reset signal is received. A reset operation must be executed immediately after power-on for devices
with reset functions.
5
POWER ON/OFF SEQUENCE
In the case of a device that uses different power supplies for the internal operation and external
interface, as a rule, switch on the external power supply after switching on the internal power supply.
When switching the power supply off, as a rule, switch off the external power supply and then the
internal power supply. Use of the reverse power on/off sequences may result in the application of an
overvoltage to the internal elements of the device, causing malfunction and degradation of internal
elements due to the passage of an abnormal current.
The correct power on/off sequence must be judged separately for each device and according to related
specifications governing the device.
6
INPUT OF SIGNAL DURING POWER OFF STATE
Do not input signals or an I/O pull-up power supply while the device is not powered. The current
injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and
the abnormal current that passes in the device at this time may cause degradation of internal elements.
Input of signals during the power off state must be judged separately for each device and according to
related specifications governing the device.

Chapter 1 Introduction
The low-voltage motor control power module from NEC Electronics is designed to drive low-voltage,
three-phase, permanent-magnet asynchronous-current (PMAC) motors such as brushless DC (BLDC)
and permanent-magnet sinusoidal motors (PMSM). The module contains a six-transistor power
MOSFET H-bridge, driver circuits, optical isolation and feedback signal conditioning circuits.
Figure 1-1:
Low-Voltage Motor Control Power Module
To evaluate a complete PMAC motor drive system, you need three parts that are all available from NEC
Electronics:
• A micro-board containing a motor-control microcontroller
• A motor control I/O board (MC-I/O-GENERAL board) that interfaces between the micro-board
and the power module
• The low-voltage power module containing the power MOSFETs
By adding a low-voltage PMAC motor and software packages that support various driving methods and
control algorithms, you can quickly explore the principals of three-phase PMAC motor control as well as
jump start your application development with minimum effort.

The low-voltage motor control power module connects to the I/O board through a 40-pin ribbon cable.
This cable carries pulse-width modulation (PWM) signals from the MCU, as well as motor-control and
sensing signals to the MCU; all of these signals pass through the I/O board. When Hall sensors are
used, connect their signal lines directly to the terminal block J5 on the I/O board.
The low-voltage motor control power module has its own power terminals. It is best to use these terminals, although you can supply the module with up to 15V/2A power through the I/O board. Use only one
of these methods of supplying power as described in sections 3.3.1 and 3.3.2 of this manual.

This section describes the power module’s signals and functions as well as its circuit implementation.
3.1 Digital-Signal Isolation
A PMAC motor requires the power-MOSFET H-bridge to switch bus voltages as high as 24 VDC. To turn
on the high-side MOSFETs, their gate voltage has to be 10 to 15V higher than their source potential
floating at half the DC bus voltage. To prevent these high voltages from affecting the CPU and controller, a digital-signal isolation circuit on the power module physically isolates the motor-side signals from
the signals on the CPU side.

Opto-couplers provide the physical separation between input and output. This galvanic isolation barrier

signal. The power module uses digital isolation for the following signals:
• PWM signals from the MCU to the power module
• Back-EMF zero-cross comparator outputs to the MCU

3.2 Analog-Signal Isolation
For analog signal isolation, the power module provides a circuit that uses input photo detectors in a
servo feedback loop. The figure below shows this circuit with an Agilent HCNR201-300 device. In this
circuit, op amps control the current to LEDs, which provide a proportional amount of light to internal
photodiodes. The input feedback loop adjusts the LED current to reflect any changes in the input. The
output photodiode converts the LED light output into current, which a voltage-follower output amplifier
then converts back into a suitable voltage.
The relationship between the input voltage (VIN) and output voltage (VOUT) is:
• VOUT = (R2/R1) * VIN
• If R1 = R2, then the output voltage closely follows the input voltage.

The power module combines the resistor at the output side (R2) with a potentiometer so that you can
adjust the (R2/R1) gain. Combined R2 value allows a gain adjustment of R2/R1. Consider, for example,
the phase-voltage detect circuit diagram shown below.

3.3 Note on Analog Signal Isolation
By default, analog signal isolators for low-side current sensing ISO14–ISO17 are optional, and the lowvoltage power module does not include them. The module does provide locations for these analog isolators; you can populate these locations with suitable components if your application requires total signal isolation. Most applications do not require such isolation because normal current levels are low, and
failures that would result in high currents are quite unlikely.
To see why, consider that the power module provides two separate ground planes, one for the 5VDC
CPU side (GND_DC) and one for the higher-voltage motor-side circuits (GND_PWR). By default, these
ground planes are connected together with jumper blocks J2 through J11 (JP2–JP11) and analog isolators ISO14-ISO17 are bypassed by solder blobs SB18–SB23. Low-side current sensing by voltage-drop
measurements on two 0.05-ohm resistors is referenced to GND_PWR. A fast-acting 4A fuse limits both
the motor current and the current through the low-side resistors. In normal operating conditions (when
the motor draws less than 4A), the voltage drop on the current-sensing resistors is less than 400 mV,
and analog isolation is not necessary.
The maximum supply voltage for the power module is 24DC, and this voltage can be present on the
sensing resistor terminals if both upper and lower MOSFET transistors conduct at the same time or
both fail. Simultaneous conduction is prevented by the dedicated cross-conduction prevention circuits
inside the IR2132S driver IC, and it is very unlikely that both high-side and low-side transistors will fail
simultaneously.
If you do want to install analog signal isolators, however, populate module locations ISO14–ISO17, and
remove solder blobs SB18–SB23 and jumpers JP2–JP11.

3.4 Back-EMF Zero-Cross-Detection Comparator
The low-voltage power module provides back-EMF comparators for sensorless motor control. BackEMF is a voltage induced in a motor’s stator windings by the permanent-magnet rotor. During each of
the six commutation periods in trapezoidal drives, only two stator windings are energized at a time,
leaving the third one floating. The back-EMF induced in this floating winding can be detected and used
to determine the rotor position.
More precisely, the zero-crossing point of the back-EMF signal is detected. The low-voltage power module includes three comparators for this task, configured as shown below. The back-EMF signal from
each motor phase passes through a resistor divider and is then compared with a virtual neutral point
created by connecting three resistors together (see the figure). With this configuration, the virtual neutral-point potential is at half the DC bus voltage—the threshold level at which the comparator output
changes from Low to High and vice versa.
The back-EMF signal is close to a sinusoidal wave with zero value at half the DC bus voltage. The comparator circuit compares the signal amplitude with the virtual neutral point, and at zero-crossing, the
comparator output changes state.

3.5 Current Sense and MCU Interface
Current measurement, current limiting and over-current sensing are often critical to the operation of
motor-control systems. Control feedback loops use measured current values to regulate a motor’s
mechanical output torque. Current limitation prevents the current in the motor windings from exceeding
the set limits, while over-current sensing triggers a fast disabling of the MCU PWM driving pins as well
as a total shut-down of the power stage. The low-voltage power module employs low-side currentsense circuits to implement all of these capabilities.

Phase_V, Phase_W and ISHUNT currents. The potentiometer allows you to adjust the gain of the
amplifier. Phase voltages IU, IV and IW are very small signals, typically 10 to 100 mV. Resistors R4 and
R5 center the amplifier's output to the midpoint of the supply voltage.

3.6 Over-Current Protection
The power module’s ISHUNT current-detect circuit detects the voltage level at the low side of a motor’s
windings. The ISHUNT voltage is a function of the current passing through a sense resistor.
The ISHUNT current-detect signal becomes ANI5_ISHUNT after it is amplified by Op amp U20 and
connects to an MCU A/D converter input through the 40-pin connector on the MC-I/O-Board. The MCU
software can monitor the A/D converter input and take appropriate current-limiting or soft-shut-down
action if the current exceeds a set limit.
For a fast hardware-based shutdown, use the on-board comparator U19 as shown below. If
ANI5_ISHUNT exceeds the threshold value preset by the 10K TrimPot, the comparator output sets the
PX_ITRIP signal, which is input to the MCU hardware shutdown pin. Upon receiving this input signal,
the MCU immediately switches all six PWM outputs to a high-impedance state, disabling the motor
drive.

As an extra protection against motor over-current (due to a locked rotor, for example), the current-sensing signal ISHUNT also connects to the over-current-sensing circuit of the IR2132S driver IC. With
R127=20K and R128=10K, the driver will shut down the outputs to the power MOSFETs if the current
exceeds 3.3A.

3.7 Safety Shut-Down
Whether based on detection of an over-current limit ISHUNT voltage or other safety criteria, the MCU
may shut-down the power stage by issuing the TRIP signal as shown below. When the TRIP signal
goes High, Q2 turns off, turning off Q1 and thus turning off power to the power MOSFETs.
Figure 3-7:
Safety Shutdown Circuit

As described above, the power module includes an IR2132S 3-phase bridge driver for the power
MOSFETs drive, and this component’s over-current detection circuit can also monitor the motor overcurrent through the ISHUNT signal if SB24 is connected and SB25 is open. When ISHUNT exceeds the
preset level, the bridge driver shuts down its outputs and sets a flag on its FAULT_B output pin. You can
select the FAULT_B signal to connect to PX_ITRIP as an option by connecting solder blob SB27 and
opening SB26 at the output of U19.
