PWR-82330
SMART POWER 3-PHASE MOTOR DRIVE
DESCRIPTION
The PWR-82330 is a smart Power 3-
phase Motor Drive Hybrid. The PWR-
82330 uses a MOSFET output stage
with a 100 Vdc rating, and can deliver
5 A continuous, 10 A peak current to
the load.
This new 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. The internal charge pump cir-
cuitry provides the required voltage to
high-side gate drives.
This provides
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
performance, high-reliability motor dri-
ves for Military and Aerospace servo-
amps and speed controls.
Among the many applications are
robotics;
electro-mechanical
valve
assemblies; 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.
harsh military environments where
shock, vibration, and temperature
extremes are evident, such as missile
applications including fin actuators and
I.R. seeker head movement. The PWR-
82330 operates over the -55°C to
+125°C temperature range and is avail-
able with military processing.
