to the VLpi pin . The PWR-82341 has a ground referenced low-
side gate drive. An internal charge pump circuit supplies the
required drive voltage to the two high-side transistors. This pro-
vides a continuous high-side gate drive; even during motor stall.
The high and low-side gate drivers control the N-channel
MOS-FET output stage. The MOSFETs used in the PWR-82341
allow output switching up to 50 kHz. The PWR-82341 does not
have internal short-circuit or overcurrent protection; which if
required, must be added externally to the hybrid.
DIGITALLY CONTROLLED INPUTS
The PWR-82341 uses Schmitt Trigger digital inputs (with hys-
teresis) to ensure high noise immunity. The trigger switches at
different points for positive and negative going signals.
Hysteresis voltage (V
H) is the difference between the positive
going voltage (V
P) and the negative going voltage (VN)
(see FIGURE 3).
The digital inputs have programmable logic levels, which allows
the hybrid to be used with different types of control logic with an
input voltage range of +5 to +15 V, such as TTL or CMOS logic.
The Vlpi pin is the logic power input for the digital circuitry inside
the hybrid. A 0.01 F, 50 V ceramic capacitor must be placed
between VLpi pin and GND as close to the hybrid as possi-
ble. When using 5 V control circuitry, an external +5 Vdc power
supply must be connected between the Vlpi pin of the hybrid,
and GND. The control circuitry can be as simple as a PWM, or
as sophisticated as a microprocessor or custom ASIC, depend-
ing on the system requirements. FIGURE 4 illustrates a typical
interface of the PWR-82341 with a motor and PWM in a Servo-
Amp System.
INTRODUCTION
The PWR-82341 is a 5 Amp, H-bridge motor drive hybrid which
incorporates a 100 Vdc MOSFET output stage for high-speed
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-82341 can be driven directly from a PWM, 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 Schmitt Trigger digital inputs that control the high and
low side of each phase. Digital protection of each phase elimi-
nates an in-line firing condition, by preventing simultaneous turn-
on of both the upper and lower transistors. This logic also con-
trols the high and low-side gate drivers. Operation from +5 to +15 V logic
levels can be programmed by applying the appropriate voltage
