6.6.5 Dead Time (t
dead
)
In order to prevent arm shoot
through a dead time between high
and low side input ON signals is
required to be included in the sys-
tem control logic. Two different val-
ues are specified on the datasheet:
A. t
dead
measured directly on
the IPM input terminals
B. t
dead
related to optocoupler
input signals using the
recommended application
circuit
The specified type B dead time is
related to standard high speed
optocouplers. (See Section 6.6.2)
By using specially selected
optocouplers with narrow distribu-
tion of switching times
the required type B dead time
could be reduced.
6.6.6 Using the Fault Signal
In order to keep the interface cir-
cuits simple the IPM uses
a single on/off output to alert the
system controller of all fault condi-
tions. The system controller can
easily determine whether the fault
signal was caused by an over tem-
perature or over current/short cir-
cuit by examining its duration.
Short circuit and over current con-
dition fault signals will be t
FO
(nominal 1.5ms) in duration. An
over temperature fault signal will be
much longer. The over temperature

fault starts when the base plate
temperature exceeds the OT level
and does not reset until the base
plate cools below the OT
r
level.
Typically this takes tens of sec-
onds.
Note:
Unused fault outputs must be prop-
erly terminated by connecting them
to the +15V on the local control
power supply. Failure to properly
terminate unused fault outputs may
result in unexpected tripping of the
modules internal protection.
