Footnotes to the Key Data
1) Both supply voltages VDC and VCC should be applied in parallel.
2) The gate current is limited by the gate resistors located on the driver.
3) If the specified value is exceeded, this indicates a driver overload. It should be noted that the driver is
not protected against overload. From 70°C to 85°C, the maximum permissible output power can be
linearly interpolated from the given data.
4) This limit is due to active clamping. Refer to “Description & Application Manual for 2SP0320T SCALE-2
IGBT Drivers” (electrical interface) or “Description & Application Manual for 2SP0320V and 2SP0320S
SCALE-2 IGBT Drivers” (fiber-optic interface).
5) Undervoltage monitoring of the primary-side supply voltage (VCC to GND). If the voltage drops below
this limit, a fault is transmitted to the corresponding output(s) (2SP0320T/2SP0320V/2SP0320S) and
the IGBTs are switched off (only 2SP0320T).
6) The input impedance can be modified to values < 18 kΩ (customer-specific solution).
7) Turn-on and turn-off threshold values can be increased (customer-specific solution).
8) 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 response time plus delay to IGBT turn-off.
9) The turn-off event of the IGBT is delayed by the specified time after the response time.
10) Factory set value. The blocking time can be reduced with an external resistor. Refer to “Description &
Application Manual for 2SP0320T SCALE-2 IGBT Drivers”.
11) Measured from the transition of the turn-on or turn-off command at the driver input to direct output
of the gate drive unit (excluding the delay of the gate resistors).
12) 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 direct output of the gate
drive unit (excluding the delay of the gate resistors).
13) Refers to the direct output of the gate drive unit (excluding the delay of the gate resistors).
14) Transmission delay of the fault state from the secondary side to the primary status outputs.
15) Measured on the host side. The fault status on the secondary side is automatically reset after the
specified time.
16) 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.
17) The gate resistors can be leaded or surface mounted. CONCEPT 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.
18) A dV/dt feedback can optionally be implemented in order to reduce the rate of rise of the collector
emitter voltage of the IGBTs at turn-off (customer-specific solution).
19) HiPot testing (= dielectric testing) must generally be restricted to suitable components. This gate
driver is suited for HiPot testing. Nevertheless, it is strongly recommended to limit the testing time to
1s slots as stipulated by EN 50178. Excessive HiPot testing at voltages much higher than 1200VAC(eff)
may lead to insulation degradation. No degradation has been observed over 1min. testing at
5000VAC(eff). Every production sample shipped to customers has undergone 100% testing at the given
value for 1s.
20) This specification guarantees that the drive information will be transferred reliably even at a high DC-
link voltage and with ultra-fast switching operations.
21) The transceivers required on the host controller side are not supplied with the gate driver. It is
recommended to use the same types as used in the gate driver. For product information refer to
www.IGBT-Driver.com/go/fiberoptics
22) The recommended transmitter current at the host controller is 20mA. A higher current may increase
jitter or delay at turn-off.
23) The typical transmitter current at the gate driver is 18mA. In case of supply undervoltage, the
minimum transmitter current at the gate driver is 12mA: this is suitable for adequate plastic optical
fibers with a length of more than 10 meters.
24) If the specified value is exceeded, this indicates a driver overload. It should be noted that the driver is
not protected against overload.
