PIN array
Fig. 2 shows the pin arrays. The input side (primary side) comprises 10 inputs (SKHI 22A / 21A 8 inputs), forming the
interface to the control circuit (see fig.1).
The output side (secondary side) of the hybrid driver shows two symmetrical groups of pins with 4 outputs, each forming
the interface to the power module. All pins are designed for a grid of 2,54 mm.

The driver is connected to a controlled + 15 V-supply
voltage. The input signal level is 0/15 V for the SKHI 22A/
21A and 0/5 V for the SKHI 22B.
SKHI 22A / 22B und SKHI 21A
In the following explanations the whole driver family will be
designated as SKHI 22B. If a special type is referred to,
the concerned driver version will explicitly be named.
Hybrid dual drivers
The driver generation SKHI 22A/B and SKHI 21A will
replace the hybrid drivers SKHI 21/22 and is suitable for all

Description of the circuit block diagram and the
functions of the driver
The SKHI 22A (SKHI 21A) is a form-, fit- and mostly
function-compatible replacement to its predecessor, the
SKHI 22 (SKHI 21).
The block diagram (fig.1) shows the inputs of the driver
(primary side) on the left side and the outputs (secondary
side) on the right.
The SKHI 22B is recommended for any new development.
It has two additional signal pins on the primary side with
which further functions may be utilized.
The following functions are allocated to the primary
side:
The SKHI 22A and SKHI 22B are available with standard
isolation (isolation testing voltage 2500 VAC, 2sec.) as
well as with an increased isolation voltage (type "H4")
(isolation testing voltage 4000 VAC, 2sec.). The SKHI 21A
is only offered with standard isolation features.
Input-Schmitt-trigger, CMOS compatible, positive logic
(input high = IGBT on)
Interlock circuit and deadtime generation of the IGBT
If one IGBT is turned on, the other IGBT of a halfbridge
cannot be switched. Additionally, a digitally adjustable
interlocking time is generated by the driver (see fig. 3),
which has to be longer than the turn-off delay time of the
IGBT. This is to avoid that one IGBT is turned on before
the other one is not completely discharged. This
protec-tion-function may be neutralized by switching the
select input (pin6) (see fig. 3). fig. 3 documents possible
interlock-times. "High" value can be achieved with no
connection and connection to 5 V as well.
Differences SKHI 22-22A (SKHI 21-21A)
Compared to the old SKHI 22/21 the new driver
SKHI 22A / 21A is absolutely compatible with regards to
pins and mostly with regards to functions. It may be
equivalently used in existing PCBs.
The following points have to be considered when
exchanging the drivers:
• Leave out the two resistors RTD for interlocking
dead time adjustment at pin 11 and pin 9.

• The interlocking time of the driver stages in
halfbridge applications is adjusted to 3,25 µs. It may
be increased up to 4,25 µs by applying a 15 V (VS)
supply voltage at Pin 9 (TDT2) (wire bridge)

As far as the SKHI 22A is concerned, the negative gate
voltage required for turn-off of the IGBT is no longer -15V,
but -7V.
Short pulse suppression
General description
The integrated short pulse suppression avoids very short
switching pulses at the power semiconductor caused by
high-frequency interference pulses at the driver input
signals. Switching pulses shorter than 500 ns are
suppressed and not transmitted to the IGBT.
The new driver generation SKHI 22A/B, SKHI 21A
consists of a hybrid component which may directly be
mounted to the PCB.
All devices necessary for driving, voltage supply, error
monitoring and potential separation are integrated in the
driver. In order to adapt the driver to the used power
module, only very few additional wiring may be necessary.
Power supply monitoring (VS)
A controlled 15 V-supply voltage is applied to the driver. If
it falls below 13 V, an error is monitored and the error
output signal switches to low level.
The forward voltage of the IGBT is detected by an
integrated short-circuit protection, which will turn off the
module when a certain threshold is exceeded.
1.The following descriptions apply to the use of the hybrid
driver for IGBTs as well as for power MOSFETs. For the
reason of shortness, only IGBTs will be mentioned in the
following. The designations "collector" and "emitter" will refer
to IGBTs, whereas for the MOSFETs "drain" and "source" are
to be read instead.
In case of short-circuit or too low supply voltage the
integrated error memory is set and an error signal is
generated.

Error monitoring and error memory
IGBT is turned off. VCEstat is the steady-state value of VCEref
and is adjusted to the required maximum value for each
IGBT by an external resistor RCE to be connected between
the terminals CCE (S6/S15) and E (S9/S12). It may not
exceed 10 V. The time constant for the delay of VCEref may
be increased by an external capacitor CCE, which is
connected in parallel to RCE. It controls the time tmin which
passes after turn-on of the IGBT before the
The error memory is set in case of under-voltage or
short-circuit of the IGBTs. In case of short-circuit, an error
signal is transmitted by the VCE-input via the pulse
transformers to the error memory. The error memory will
lock all switching pulses to the IGBTs and trigger the error
output (P10) of the driver. The error output consists of an
open collector transistor, which directs the signal to earth
in case of error. SEMIKRON recommends the user to
provide for a pull-up resistor directly connected to the error
evaluation board and to adapt the error level to the desired
signal voltage this way. The open collector transistor may
be connected to max. 30 V / 15 mA. If several SKHI 22Bs

Adaptation to error signal level
SEMIKRON recommends to start-up operation using the
values recommended by SEMIKRON and to optimize the
values gradually according to the IGBT switching
behaviour and overvoltage peaks within the specific
circuitry.
An open collector transistor is used as error terminal,
which, in case of error, leads the signal to earth. The signal
has to be adapted to the evaluation circuit's voltage level
by means of an externally connected pull-up resistor. The
maximum load applied to the transistor shall be 30 V / 15
mA.

Further application notes
A typical interlocking time value is 3,25 μs (P9 = GND; P5
and P6 open). For SKHI 22A / 21A the terminals TDT1
(P5) and SELECT (P6) are not existing. The interlocking
time has been fixed to 3,25 μs and may only be increased
to 4,25 μs by connecting TDT2 (P9) to VS (P13).
The CMOS-inputs of the hybrid driver are extremely
sensitive to over-voltage. Voltages higher than VS
+
0,3 V or below – 0,3 V may destroy these inputs.
Therefore, control signal over-voltages exceeding the
above values have to be avoided.

If a PCB is directly plugged to IGBT modules, the PCB has
to be fixed to the heat sink by thread bolts.
Persons working with CMOS-devices have to wear a
grounded bracelet. Any synthetic floor coverings must not
be statically chargeable. Even during transportation the
input terminals have to be short-circuited using, for
example, conductive rubber. Worktables have to be
grounded. The same safety requirements apply to
MOSFET- and IGBT-modules!
The temperature of the solder must not exceed 265°C,
and solder time must not exceed 4 seconds. The ambient
temperature must not exceed the specified maximum
storage temperature of the driver.
The driver is not suited for hot air reflow or infrared reflow
soldering processes.
The connecting leads between hybrid driver and the
power module should be as short as possible, the driver
leads should be twisted.
Storage hints
Any parasitic inductances within the DC-link have to be
minimized. Over-voltages may be absorbed by C- or
RCD-snubbers between the main terminals for PLUS and
MINUS of the power module.
- Store driver only in original packaging.
- Avoid contamination of driver's surface during storage,
handling and processing.
- Please use the driver within one year after driver
manufacturing date. The manufacturing date is marked on
the driver. Usage of the driver beyond this shelf life could
compromise product long term reliability.
- Further storage conditions are indicated in the data
sheet
When first operating
a
newly developed circuit,
SEMIKRON recommends to apply low collector voltage
and load current in the beginning and to increase these
values gradually, observing the turn-off behaviour of the
free-wheeling diode and the turn-off voltage spikes
generated accross the IGBT. An oscillographic control will
be necessary. In addition to that the case temperature of
the module has to be monitored. When the circuit works
correctly under rated operation conditions, short-circuit
testing may be done, starting again with low collector
voltage.
Environmental conditions
The driver is type tested under the environmental
conditions below.
It is important to feed any errors back to the control circuit
and to switch off the device immediately in such events.
Repeated turn-on of the IGBT into a short circuit with a
high frequency may destroy the device.
Thermal cycling test:
- 100 cycle -40°C … +85°C
Mechanical fixing on PCB:
In applications with mechanical vibrations do not use a
ty-rap for fixing the driver, but - after soldering and testing
- apply special glue. Recommended types: CIBA GEIGY
XP 5090 + 5091; PACTAN 5011; WACKER A33 (ivory) or
N199 (transparent), applied around the case edge (forms
a concave mould). The housing may not be pressed on the
PCB; do not twist the PCB with the driver soldered on,
otherwise the internal ceramics may crack. The driver is
not suitable for big PCBs.
Vibration test according DIN IEC 68-2-6:
- Sinusoidal sweep: 10 Hz … 100 Hz
-1 Octave / min.
-Acceleration: 1,5 g
-Axes: 3 (x, y, z)
-26 sweeps per axis
-Driver soldered on board SKPC 2006 (L x B x H = 97,0
x 67,5 x 1,5mm)
-Driver stuck with glue on printed circuit board (see
application notes)
Proven, within the scope of the product qualification, was
the use of the driver with the printed circuit board
SKPC 2006 ( L x B x H = 97,0 x 67,5 x 1,5 mm). During the
test, the driver was stuck with glue on the printed circuit
board. Based on this information the technical conclusion
arises, that in an application with big printed circuit boards,
this board must be supported and reinforced in the area of
the driver.
Shock test according DIN IEC 68-2-27:
- Half-sinusoidal pulse
-Peak acceleration: 5 g
-Shock width: 18ms
-3 shocks in each direction (±x, ±y und ±z)
-18 shocks in total
-Driver soldered on board SKPC 2006 (L x B x H = 97,0
