12) The maximum dynamic voltage between auxiliary emitters of parallel-connected drivers due to
asymmetrical operation at turn-on and turn-off must be limited to the given value.
13) Maximum allowed rate of change of auxiliary emitter voltage of parallel connected drivers. This
specification guarantees that the drive information will be transferred reliably even with high rate of
change of auxiliary emitter voltages (asymmetrical operation).
14) Dynamic voltages between auxiliary emitters of parallel connected drivers at turn-on and turn-off lead
to equalizing currents over the X2 or X3 bus. The peak and RMS values of the resulting current must
be limited to the given value.
15) Undervoltage monitoring of the secondary-side supply voltage (Viso to Vee and Vee to COM which
correspond with the approximate turn-on and turn-off gate-emitter voltages). If the corresponding
voltage drops below this limit on 1SP0335x2Mx (masters), all paralleled IGBTs (master and slaves) are
switched off and a fault is transmitted to the status output. If the corresponding voltage drops below
this limit on 1SP0335D2Sx (slaves), the corresponding IGBT is switched off. If the IGBT was turned
on, a fault will be generated by the gate-monitoring function on the master which will turn off all
paralleled IGBT after the corresponding delay.
16) The mean value V

of all gate voltages (master and all slaves) is filtered and compared to the
given values at turn-on and turn-off. If the specified values are exceeded (V

at turn-off) after the given filter delay, the driver turns off all parallel-
connected IGBTs and a fault is transmitted to the status output.
17) A dynamic Vce protection is implemented on the driver. The maximum allowed Vce voltage at turn-on
is dynamically adjusted in order to better fit to the IGBT characteristics at turn-on. At the end of the
turn-on process the given static value applies.
18) The resulting pulse width of the direct output of the gate drive unit for short-circuit type I (excluding
the delay of the gate resistors) is the sum of the response time plus the delay to IGBT turn-off.
19) The turn-off event of the IGBT is delayed by the specified time after the response time.
20) Including the delay of the external fiber-optic links (cable length: 1m). Measured from the transition
of the turn-on or turn-off command at the optical transmitter on the host controller side to the direct
output of the gate drive unit (excluding the delay of the gate resistors).
21) Output rise and fall times are measured between 10% and 90% of the nominal output swing. The
values are given for the driver side of the gate resistors with 2Ω/1uF load. The time constant of the
output load in conjunction with the present gate resistors leads to an additional delay at their load
side.
22) Delay of external fiber-optic links. Measured from the driver secondary side (ASIC output) to the
optical receiver on the host controller.
23) Measured on the host side. The fault status on the secondary side is automatically reset after the
specified time.
24) Including the delay of the external fiber-optic links. Measured from the transition of the turn-on or
turn-off command at the optical transmitter on the host controller side to the transition of the
acknowledge signal at the optical receiver on the host controller side.
25) The gate resistors and the auxiliary gate capacitor are not assembled on this IGBT gate driver. They
must be assembled by the user according to the paragraph on “Gate Resistor Assembly”.
26) The driver supply voltage VDC is split into two distinct voltages on the driver. The first one is the turn-
on voltage which is regulated at about 15V. The difference between VDC and the turn-on voltage is
the turn-off voltage which is not regulated and mainly dependent on the driver input voltage VDC.
27) The fault status is set as long as the gate monitoring fault is present. The given value applies if the
driver goes from the “off state” to the “on state” and the gate-emitter voltage of one or more parallel
connected drivers does not turn on. If the driver goes from the “on state” to the “off state” and the
gate-emitter voltage of one or more parallel connected drivers does not turn off, the fault status is
applied as long as the gate monitoring fault is present.
28) The maximum switching frequency is not defined, as it depends on the IGBT module used. Please
consult the corresponding driver data sheet for more information.
