PWR-82340 AND PWR-82342
SMART POWER H-BRIDGE
MOTOR DRIVES
FEATURES
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 rat-
ing and an IGBT output stage. Both
types have individual fast recovery
diodes internally connected across the
output drive transistors to clamp induc-
tive 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 simultaneous turn-on of in-line
transistors, thus eliminating a shoot-
thru condition. The internal logic con-
trols 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 volt-
age source to the floating high side
gate drives. This provides constant out-
put performance for switching frequen-
cies from DC to 50 kHz.
APPLICATIONS
Packaged in small cases, these hybrids
are an excellent choice for high perfor-
mance, high reliability motor drives for
military and aerospace servo-amps
and speed controls. Among the many
applications are robotics; electro-
mechanical valve assemblies; actua-
tor systems for flight control surfaces
on military and commercial aircraft;
antenna and radar positioning; fan and
blower motors for environmental con-
ditioning; thrust and vector position
control of mini subs, drones, and
RPV's; compressor motors for cryo-
genic coolers; and high-power invert-
ers. The PWR-82340/342 hybrids are
ideal for harsh military environments
where shock, vibration, and tempera-
ture extremes are evident, such as
missile applications where fin actuator
systems control missile direction. The
PWR-82340 and PWR-82342 operate
over the -55擄C to +125擄C temperature
range and are available with military
processing.
