INTRODUCTION
The 3-phase PWR-82331 and PWR-82333 are 30 A motor drive
hybrids rated at +200 V and +500 V respectively. The PWR-
82331 uses a MOSFET output stage and the PWR-82333 has
an IGBT output stage for high speed, high current, and high effi-
ciency operation. The PWR-82333 also offers high-voltage per-
formance of an IGBT for use in +270 V systems. These motor dri-
ves are ideal for use in high-performance motion control sys-
tems, servo amplifiers, and motor speed control designs.
Furthermore, multi-axis systems requiring multiple drive stages
can benefit from the small size of these power drives.
The PWR-82331/82333 can be driven directly from the commu-
tation logic, DSP, or a custom ASIC that supplies digital signals
to control the upper and lower transistors of each phase. These
highly integrated drive stages have Schmitt trigger digital inputs

that control the high and low side of each phase. Digital protec-
tion of each phase eliminates an in-line firing condition by pre-
venting simultaneous turn-on of both the upper and lower tran-
sistors. The logic controls the high- and low-side gate drivers.
Operation from +5 to +15 V logic levels can be programmed by
applying the appropriate voltage to pin 16 (VLPI). The PWR-
82331/82333 has a ground referenced low-side gate drive. An
internal dc-dc converter supplies a floating output to each side of
the three high-side drives. This provides a continuous high-side
gate drive even during the motor stall. Pin 15 (VLPO) supplies a
+15 V output, which can be used to power the internal logic when
system usage requires +15 V logic. The high- and low-side gate
drivers control the N-channel MOSFET or IGBT output stage.
The MOSFETs used in the PWR-82331 allow output switching
up to 50 kHz, while the high-speed IGBTs in the PWR-82333 can
switch at 25 kHz. A flyback diode parallels each output transistor
and controls the regenerative energy produced by the motor.
These fast recovery diodes have faster reverse switching times
than the intrinsic body diode of the MOSFETs used in the PWR-
82331. They also protect the IGBTs used in the PWR-82333
from exceeding their emitter-to-collector breakdown voltage.
Use of a copper case and solder attachment of the output tran-
sistors achieves a low thermal resistance of 0.85° C/W maxi-
mum. Care should be taken to adequately heatsink these motor
drives to maintain a case temperature of 125°C. Junction tem-
peratures should not exceed 150°C. The PWR-82331/82333 do
not have internal short-circuit or overcurrent protection. For pro-
tection of the output transistors, these features must be added
externally to the hybrid.
