PWR-82341
SMART POWER H-BRIDGE MOTOR
DRIVE
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 5A continuous, 10 A peak cur-
rent 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鈥檇 in each
phase to prevent simultaneous turn
on of in-line transistors, thus eliminat-
ing 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 circuit provides the required
voltage to the high-side gate drives.
This ensures constant output perfor-
mance 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 drives 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鈥檚; and com-
pressor 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 operates over the -55擄C
to +125擄C temperature range and is
available with military processing.
