INTRODUCTION
The 3-phase PWR-82330 is a 5 A motor drive hybrid which incor-
porates a 100 Vdc MOSFET output stage for high-speed and high-
efficiency operation. This motor drive is ideal for use in high-perfor-
mance 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-82330 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 integrat-
ed drive stage has schmitt trigger 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 simul-
taneous turn-on of both the upper and lower transistors. The

logic controls the high and low-side gate drivers. Operation from
5 to 15 V logic levels can be programmed by applying the appro-
priate voltage to pin 6 (VLPI). The PWR-82330 has a ground ref-
erenced low-side gate drive. An internal charge pump circuit
supplies the required drive voltage to each of the three high-side
transistors. 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-82330 allow output switching up to 50 kHz. The PWR-
82330 does not have an internal short-circuit or overcurrent pro-
tection, which if required, must be added externally to the hybrid.
DIGITALLY CONTROLLED INPUTS
The PWR-82330 uses the Schmitt triggered digital inputs (with
hysteresis) to ensure high noise immunity. The trigger switches
at different points for positive and negative going signals.
Hysteresis voltage (VH) is the difference between the positive
going voltage (VP) and the negative going voltage (VN) (see FIG-
URE 3). The digital inputs have programmable logic levels, which
allows the hybrid to be used with different types of commutation
logic with an input voltage range of 5-15 V, such as TTL or CMOS
logic. Pin 6 is the logic power input (VLPI) for the digital circuitry
inside the hybrid. A 0.01 F, 50 V ceramic capacitor must be
placed between this pin (6) and GND as close to the hybrid
as possible. When using 15 V control circuitry, an external +15
Vdc power supply must be connected between pin 6 of the
hybrid, and GND. The commutation / control circuitry can be as
simple as discrete logic with PWM, or as sophisticated as a
microprocessor or custom ASIC, depending on the system
requirements.
FIGURE 4 illustrates a typical interface of the
PWR-82330 with a motor and commutation logic in a Servo-Amp
System. (Refer to AN/H-3 application note for more details.)
