SCALE™-2 1SP0335x2x1(C)-DIM750ASM65-TS000
Data Sheet
13) Maximum allowed rate of change of auxiliary emitter voltage of parallel connected drivers.
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 1SP0335x2x1(C) (mains), all paralleled IGBTs (main and peripherals)
are switched off and a fault is transmitted to the status output. If the corresponding voltage drops
below this limit on 1SP0335D2S1(C) (peripherals), the corresponding IGBT is switched off. If the IGBT
was turned on, a fault will be generated by the gate-monitoring function on the main driver which will
turn off all paralleled IGBTs after the corresponding delay.
16) The mean value VGE,mean of all gate voltages (main and all peripherals) is filtered and compared to the
given values at turn-on and turn-off. If the specified values are exceeded (VGE,mean<VGE,on,min at turn-on
resp. VGE,mean>VGE,off,max 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 (cable length: 1m).
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 (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
transition of the acknowledge signal at the optical receiver on the host controller side.
25) The gate resistors can be leaded or surface mounted. Power Integrations reserves the right to
determine which type will be used. Typically, higher quantities will be produced with SMD resistors
and small quantities with leaded resistors.
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 storage temperature inside the original package (1) or in case the coating material of coated
products may touch external parts (2) must be limited to the given value.
Otherwise, it is limited to 90°C.
29) The component surface temperature, which may strongly vary depending on the operating condition,
must be limited to the given value for coated driver versions to ensure long-term reliability of the
coating material.
