FIGURE 3. HYSTERESIS DEFINITION AND CHARACTERISTICS
SHUT-DOWN INPUT (VSd)
Pin 12 (Vsd) provides a digital shut-down input, which allows the
user to completely turn-off both the upper and lower-output tran-
sistors in all 3 phases. Application of a logic ‘1’ to the VSd input
will latch the Digital Control / Protection circuitry thereby turning
off all output transistors. The Digital Control/Protection circuitry
remains latched in the off state and will not respond to signals on
the VL or VU inputs while the VSd has a logic ‘1’ applied. When
the user or the sense circuitry (as in FIGURE 6) returns the VSd
input to a logic ‘0’, and then the user sets the VL and VU inputs
to a logic ‘0’ the output of the Digital Control / Protection circuit-
ry will clear the internal latch. When the next rising edge (see
FIGURE 5) occurs on the VL or VU digital inputs, the outputs
transistors will respond to the corresponding digital input. This
feature can be used with external current limit or temperature
sense circuitry to disable the drive if a fault condition occurs (see
FIGURE 6).
INTERNAL PROTECTION CIRCUITRY
The hybrid contains digital protection circuitry, which prevents in-
line transistors from conducting simultaneously. This, in effect,
would short circuit the power supply and would damage the out-
put stage of the hybrid. The circuitry allows only proper input sig-
nal patterns to cause output conduction. TABLE 3 lists the input/
output timing relationships. If an improper input requested that
the upper and lower transistors of the same phase conduct
together, the output would be a high impedance until removal of
the illegal code from the input of the PWR-82330. A dead time
of 400 nsec minimum should still be maintained between
