DESCRIPTION
The PWR-82340 and PWR-82342 are 30 A H-bridge motor drive hybrids. The
PWR-82340 has a 200 V rating and uses MOSFETs in the output stage while
the PWR-82342 has a 500 V rating and an IGBT output stage. Both types
have individual fast recovery diodes internally connected across the output
drive transistors to clamp inductive flyback. This new series of Smart Power
Motor Drives has CMOS Schmitt Trigger inputs for high noise immunity. High-
and low-side input logic signals are XOR'd in each phase to prevent simulta-
neous turn-on of in-line transistors, thus eliminating a shoot-thru condition.
The internal logic controls the high- and low-side gate drives for each phase
and can operate from +5 to +15 V logic levels. The internal power supply
provides a constant voltage source to the floating high side gate drives. This
provides constant output performance for switching frequencies from DC to
50 kHz.
APPLICATIONS
Packaged in small cases, these hybrids are an excellent choice for high per-
formance, high reliability motor drives for military and aerospace servo-amps
and speed controls. Among the many applications are robotics; electro-
mechanical valve assemblies; actuator systems for flight control surfaces on
military and commercial aircraft; antenna and radar positioning; fan and
blower motors for environmental conditioning; thrust and vector position con-
trol of mini subs, drones, and RPV's; compressor motors for cryogenic cool-
ers; and high-power inverters. The PWR-82340/342 hybrids are ideal for
harsh military environments where shock, vibration, and temperature
extremes are evident, such as missile applications where fin actuator sys-
tems control missile direction. The PWR-82340 and PWR-82342 operate
over the -55°C to +125°C temperature range and are available with military
processing.

INTRODUCTION
The PWR-82340 and PWR-82342 are 30 A motor drive hybrids
rated at 200 V and 500 V respectively. The PWR-82340 uses a
MOSFET output stage and the PWR-82342 has an IGBT output
stage for high speed, high current, and high efficiency operation.
The PWR-82342 also offers high voltage performance of an
IGBT for use in 270 V systems. These motor drives are ideal for
use in high performance motion control systems, servo amplifi-
ers, and motor speed control designs. Furthermore, Multiaxis
systems requiring multiple drive stages can benefit from the
small size of these power drives.
The PWR-82340/342 can be driven directly from a PWM, DSP,
or a custom ASIC that supplies digital signals to control the
upper and lower transistors of each phase. These highly inte-
grated drive stages have Schmitt trigger digital inputs that control
the high and low side of each phase. Digital protection of each
phase eliminates an in-line firing condition by preventing simulta-
neous turn-on of both the upper and lower transistors. The logic
controls the high- and low-side gate drivers.
Operation from +5 to +15 V logic levels can be programmed by
applying the appropriate voltage to pin 12 (V
LPI
). The PWR-
82340/342 has a ground referenced low-side gate drive.

PWR-82340/PWR-82342
M-1/10-0
An internal DC-DC converter supplies a floating output to each
of the two high-side drives. This provides a continuous high-side
gate drive even during a motor stall. Pin 11 (VLPO) supplies a
+15 V output, which can be used to power the internal logic when
system usage requires +15 V logic. The high- and low-side gate
drivers control the N-channel MOSFET or IGBT output stage.
The MOSFETs used in the PWR-82340 allow output switching
up to 50 kHz, while the high-speed IGBTs in the PWR-82342 can
switch at 25 kHz. A flyback diode parallels each output transistor
and controls the regenerative energy produced by the motor.
These fast recovery diodes have faster reverse switching times
than the intrinsic body diode of the MOSFETs used in the PWR-
82340. They also protect the IGBTs used in the PWR-82342
from exceeding their Emitter-to-Collector breakdown voltage.
Use of a copper case and solder attachment of the output tran-
sistors achieves a low thermal resistance of 0.85°C/W maximum.
Care should be taken to adequately heatsink these motor drives
to maintain a case temperature of +125°C. Junction tempera-
tures should not exceed +150°C. The PWR-82340/342 does not
have internal short circuit or overcurrent protection which, if
required, must be added externally to the hybrid.
If the bus voltage (Vcc) is between 15 < V < 45V that may be
used for the power supply as well by using the configuration
shown in FIGURE 3B. In most avionic systems this can be
accomplished by connecting the Vb pin to the MIL-STD-704D,
+28 Volt bus.
In any case, a 0.01 µf decoupling capacitor (Cb) must be con-
nected between Vb (pin 8) and GND.

BIAS VOLTAGES
The PWR-82340 and PWR-82342 motor drive hybrids require a
power supply (Vb) for operation. Based on the Vb, the hybrid
generates two independent, floating supplies internally, which
eliminates the need for external bias voltages for each phase. In
order for the internal power supply to generate these voltages,
the input bias voltage (Vb) must be between +15 to +45 Vdc and
configured as shown in FIGURE 3A.

DIGITALLY CONTROLLED INPUTS
The PWR-82340 and PWR-82342 use Schmitt triggered digital
inputs (with hysteresis) to ensure high noise immunity. The trigger
switches at different points for positive and negative going sig-
nals. Hysteresis voltage (VH) is the difference between the posi-
tive going voltage (VP) and the negative going voltage (VN) (see
FIGURE 4). The digital inputs have programmable logic levels,
which allows the hybrid to be used with different types of control
logic with an input voltage range of +5 to +15 V, such as TTL or
CMOS logic. The PWR-82340 and PWR-82342 internal power
supply generates a +15 Vdc (VLPO) on pin 11. This output can
only be used to power the internal digital circuitry within the
hybrid.
Do not use this +15 V output to power any circuitry
external to the hybrid.
Pin 12 is the logic power input (VLPI) for
the digital circuitry inside the hybrid.
A 0.01 uF, 50 V ceramic
capacitor must be placed between this pin (12) and GND as
close to the hybrid as possible.
When using 15 V control cir-
cuitry, the logic power input (pin 12) can be connected directly to
the logic power output (pin 11) of the hybrid. There is no need
for an additional external power supply.
When using 5 V con-
trol logic, an external +5 VDC supply must be connected
between pin 12 of the hybrid, and GND — leave Pin 11 open
(N/C).
The control circuitry can be as simple as a PWM, or as
sophisticated as a microprocessor or custom ASIC, depending
on the system requirements. The Block Diagram in FIGURE 5
shows a typical interface of the PWR-82340 and PWR-82342
with a motor and control logic in a Servo-Amp System.
