FEATURES
DESCRIPTION
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.
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.

Capability
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.
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 PWR-82330 hybrid is ideal for
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.
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.
