DIGITALLY CONTROLLED INPUTS
The PWR-82340 and PWR-82342 use Schmitt triggered digital
inputs (with hysteresis) to ensure high noise immunity. The trig-
ger 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 FIGURE 7). The digital inputs have programmable logic lev-
els, 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 PWR-82340 and PWR-82342 internal
power supply generates a +15 Vdc (VLPO) on pin 11. This out-
put can only be used to power the internal digital circuitry within
the hybrid. Do not use this +15 V output to power any cir-
cuitry external to the hybrid. Pin 12 is the logic power input
(VLPI) for the digital circuitry inside the hybrid. A 0.01 uF, 50 V
ceramic capacitor must be placed between this pin (12) and
GND as close to the hybrid as possible. When using 15 V
control circuitry, the logic power input (pin 12) can be connected
directly to the logic power output (pin 11) of the hybrid. There is
no need for an additional external power supply. When using 5
V control logic, an external +5 VDC supply must be con-
nected between pin 12 of the hybrid, and GND — leave Pin
11 open (N/C). The control circuitry can be as simple as a
PWM, or as sophisticated as a microprocessor or custom ASIC,
depending on the system requirements. The Block Diagram in
FIGURE 8 shows a typical interface of the PWR-82340 and
PWR-82342 with a motor and control logic in a Servo-Amp
System.

To prevent damage to the internal drive circuitry, the differential voltage between
GND (pins 7,18) and Vss (pins 1,4) must not exceed ±3V max, dc or peak.
