INTRODUCTION
The 3-Phase PWR-82332 is a 19A motor drive rated at 400V.
The PWR-82332 uses a MOSFET output stage for high speed,
high current, and high-efficiency operation. This motor drive is
ideal for use in high-performance motion control systems, servo
amplifiers, and motor speed control designs. Furthermore, multi-
axis systems requiring multiple drive stages can-benefit from the
small size of this power drive.
The PWR-82332 can be driven directly from commutation logic,
DSP, or a custom ASIC that supplies digital signals to control the
upper and lower transistors of each phase. This highly integrated
drive stage has digital inputs that control the high and low side of
each phase. Digital protection of each phase eliminates an in-line
firing condition, by preventing simultaneous turn-on of both the
upper and lower transistors in a given phase. The PWR-82332 has
a ground referenced low-side gate drive. An internal dc-dc con-
verter supplies a floating output to each of the 3 high side drives.
This provides a continuous high-side gate drive even during a
motor stall. The high and low-side gate drivers control the N-
channel MOSFET output stage. The MOSFETs used in the
PWR-82332 allow output switching up to 50 kHz.
A flyback
diode parallels each output transistor and controls the regenera-
tive 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-82332. Care should be taken
to adequately heatsink these motor drives to maintain a case
temperature under 125°C.
Junction temperatures should not
exceed 150°C.
The PWR-82332 does not have an internal
short-circuit or overcurrent protection. For protection of the out-
put transistors, these features must be added external to the
hybrid.

BIAS VOLTAGES
The PWR-82332 motor drive hybrid requires a single input bias
supply for operation. The hybrid generates three independent,
floating supplies internally, which eliminates the need for exter-
nal bias voltages for each phase.
In order for the internal power supply to generate these voltages,
the input bias voltages (Vb) must be from 15 to 50 Vdc.
Any voltage available in the system in the 15 to 50 Vdc range can
be directly connected to the Vb pin of the hybrid. (See FIGURE
3).

F decoupling capacitor must be connected between Vb
(pin 12) and GND and VLPI (pin 16) to GND.
