DESCRIPTION
The PWR-82341 is a smart Power H-Bridge Motor Drive hybrid. The PWR-
82341 uses a MOSFET output stage with a 100Vdc rating, and can deliver
5 A continuous, 10 A peak current to the load.
This Smart Power Motor Drive has CMOS Schmitt Trigger inputs for high
noise immunity. High and low-side input logic signals are XOR’d in each
phase to prevent simultaneous turn on of in-line transistors, thus eliminating
a shoot through condition.
The internal logic controls the high and low-side gate drivers for each phase
and can operate from +5 to +15 V logic levels. An internal charge pump cir-
cuit provides the required voltage to the high-side gate drives. This ensures
constant output performance for switching frequencies from DC to 50 kHz.
APPLICATIONS
Packaged in a small case, 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 assem-
blies; actuator systems; antenna and radar positioning; fan and blower
motors for environmental conditioning; position control of mini-subs, drones,
and RPV’s; and compressor motors for cryogenic coolers.
The PWR-82341 hybrid is ideal for harsh military environments where shock,
vibration, and temperature extremes are evident, such as missile applications
including fin actuators and I. seeker head movement. The PWR-82341 oper-
ates over the -55°C to +125°C temperature range.

INTRODUCTION
The PWR-82341 is a 5 Amp, H-bridge motor drive hybrid which
incorporates a 100 Vdc MOSFET output stage for high-speed
and high-efficiency operation. This motor drive is ideal for use in
high-performance motion control systems, servo amplifiers, and
motor speed control designs. Furthermore, Multi-axis systems
requiring multiple drive stages can benefit from the small size of
this power drive.
The PWR-82341 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. This highly integrated drive
stage has Schmitt Trigger digital inputs that control the high and
low side of each phase. Digital protection of each phase elimi-
nates an in-line firing condition, by preventing simultaneous turn-
on of both the upper and lower transistors. This logic also controls
the high and low-side gate drivers. Operation from +5 to +15 V logic lev-
els can be programmed by applying the appropriate voltage to
INPUTS:
the VLpi pin . The PWR-82341 has a ground referenced low-side
gate drive. An internal charge pump circuit supplies the required
drive voltage to the two high-side transistors. This provides a
continuous high-side gate drive; even during motor stall. The high
and low-side gate drivers control the N-channel MOS-FET out-
put stage. The MOSFETs used in the PWR-82341 allow output
switching up to 50 kHz. The PWR-82341 does not have internal
short-circuit or overcurrent protection; which if required, must be
added externally to the hybrid.
DIGITALLY CONTROLLED INPUTS
The PWR-82341 uses Schmitt Trigger digital inputs (with hys-
teresis) to ensure high noise immunity. The trigger switches at
different points for positive and negative going signals.
Hysteresis voltage (VH) is the difference between the positive
going voltage (V P ) and the negative going voltage (V
N
)
(see FIGURE 3).
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 Vlpi pin is the logic power input for the digital circuitry inside
the hybrid.
A 0.01 µF, 50 V ceramic capacitor must be placed
between VLpi pin and GND as close to the hybrid as possi-
ble.
When using 5 V control circuitry, an external +5 Vdc power
supply must be connected between the Vlpi pin of the hybrid, and
GND. The control circuitry can be as simple as a PWM, or as
sophisticated as a microprocessor or custom ASIC, depending
on the system requirements. FIGURE 4 illustrates a typical inter-
face of the PWR-82341 with a motor and PWM in a Servo-Amp
System.
