Absolute maximum ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device.  
Functional operation of the device at conditions beyond those indicated in the operational sections of this data sheet is not  
implied.  
1.4 ESD Warning  
ESD (electrostatic discharge) sensitive device. Electrostatic charges can readily accumulate on test equipment and  
the human body in excess of 4000 Volts. This energy can discharge without detection. Although the IX6611 features  
proprietary ESD protection circuitry, permanent damage might be sustained if subjected to high energy electrostatic  
discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

3. Theory of Operation  
The IX6611 integrated circuit is designed to provide gate drive for high power IGBT modules. The device converts the  
incoming isolated PWM logic signals into a +15V/-5V bipolar gate drive signal with a typical 10A peak drive current  
capability.  
3.1 Detailed Circuit Description  
3.1.2 Pulse Recovery Logic  
The Pulse Recovery Logic block receives the leading  
edge pulse and trailing edge pulse signals from the  
Input Interface and reconstructs the complementary  
IN and INB drive signals. These complementary  
signals are level shifted to drive the Gate Control Logic  
block.  
3.1.1 Input Interface  
The Input Interface block of the gate driver is designed  
to be compatible with pulse transformers. The receiver  
inputs, RCVP and RCVN, are connected to the pulse  
transformer secondary through a diode/resistor  
network as shown on the typical application diagram  
Figure 6 on page 11. The Input Interface contains  
high speed Schmitt trigger buffers with 1V typical  
hysteresis. To reject noise and high frequency  
interference, a well matched full differential  
architecture is used for the Schmitt trigger buffer  
receivers.  
3.1.3 Gate Control Logic  
The Gate Control Logic block inserts a fixed dead time  
between the incoming IN and INB signals to generate  
non-overlapping PGATE drive and NGATE drive  
signals. This dead time is sufficient to prevent  
R00A  
PRELIMINARY  
11  
IX6611  
shoot-through in the large output P-channel and  
N-channel devices.  
Traditional de-saturation protection can also be  
implemented using a large ratio resistor divider  
connected across the collector and the emitter. A  
noise filter (RC) at the current sense input may be  
required due to low sense voltage.  
The Gate Control Logic block also receives power  
supply status, IGBT over-current status, and IGBT  
collector over-voltage status signals. Based on these  
signals the output stage is conditioned accordingly as  
shown in Figure 2 on page 9, Figure 3 on page 9,  
Figure 4 on page 10 and Figure 5 on page 10.  
3.1.6 Leading Edge Blanking Circuit  
To prevent false tripping of the OC Comparator, its  
input is grounded for a fixed amount of time during the  
turn-on of the IGBT.  
If a supply under-voltage or a supply over-voltage fault  
event is detected during the leading edge of the input  
PWM gate drive cycle, then the driver is disabled for  
the entire duration of the cycle. Normal operation  
resumes at the beginning of the next cycle only if there  
is no supply fault condition.  
Leading Edge Blanking Circuit sets the blanking time  
and it is programmable through an external capacitor.  
The OC Comparator input is also grounded during the  
off time of the driver.  
If an IGBT over-current fault occurs during the ON  
time of the PWM cycle, then the IGBT driver output is  
forced low for the remainder of the cycle. Normal  
operation resumes at the beginning of the next PWM  
gate drive cycle.  
3.1.7 Active Clamp Comparator  
IX6611 contains an Active Clamp Comparator (ACL  
COMP) with a 3.1V threshold that can be used for  
implementing an advanced active clamping technique  
as shown in application circuit diagram Figure 6 on  
During the OFF time of the IGBT driver, if an IGBT  
collector over-voltage fault occurs, then for the  
remainder of the cycle the output PFET is turned off  
and the output NFET state is controlled by the ACL  
comparator as shown in the Figure 5 on page 10.  
Normal operation resumes at the beginning of the next  
PWM gate drive cycle.  
page 11. ACL COMP threshold is with respect to V  
.
EE  
During the turn off of the IGBT, the ACL comparator  
can detect an over voltage, if the collector voltage  
rises above the breakdown voltage of the diode  
connected at the collector. In the over voltage  
condition the ACL comparator forces the gate driver  
output to a tri-state condition and the IGBT starts to  
turn on due to the break down diode current charging  
the IGBT gate. Once the IGBT turns on, its collector  
3.1.4 IGBT Drive Outputs  
IX6611 contains separate 10A peak source and sink  
outputs. Separated sink and source outputs allow  
independent gate charge and discharge control  
without an external diode. The internal dead-time  
circuit eliminates the cross conduction of the source  
and sink outputs.  
voltage falls, the diode recovers from break down, and  
the ACL comparator turns on the NMOS output and  
forces the IGBT gate low. This sequence may repeat  
several times until the energy in the external  
inductance is dissipated.  
ACL comparator is active only when the driver output  
PFET is OFF.  
3.1.5 Over Current Comparator  
IX6611 contains an Over Current Comparator (OC  
COMP) with a 300mV threshold. This comparator is  
used for sensing over-current conditions in the  
external IGBT.  
3.1.8 Thermal Shutdown (THSD)  
IX6611 contains a Thermal Shutdown circuit to protect  
the device against the damage due to excessive die  
temperature. When the junction temperature exceeds  
150°C, the input signals to the gate driver and the ACL  
comparator are disabled and the gate driver output is  
forced low. Device resumes normal operation when  
the junction temperature falls below 130°C.  
Emitter current sense can be implemented either by  
using a low value current shunt or an IGBT with a  
secondary current sense output.  
The current-sense method works well for high gain  
IGBTs that do not have inherent short circuit  
protection. Careful application board layout is  
mandatory due to low sense voltage.  
3.1.9 Output Fault Pulse Generator  
An IGBT over current fault event can occur any time  
during the ON time of the gate drive signal. When an  
12  
PRELIMINARY  
R00A  
IX6611  
over current occurs the Output Faults Pulse Generator  
creates a narrow 200ns pulse that will be used by the  
Fault Control Logic to communicate the fault condition  
to the primary side across the barrier.  
The UVLO circuit is operational at V no greater than  
CC  
3V and it keeps the gate driver output low until V is  
CC  
raises above the UVLO threshold.  
3.1.12 Fault Control Logic  
3.1.10 5V Regulator  
Fault information is communicated to the primary side  
through the pulse transformer interface. Fault Control  
Logic provides the gate drive to the high current  
switches connected to the primary terminals of the  
pulse transformer. Narrow pulses are used to drive the  
high current switches. Based on the fault type, the fault  
control logic selects the narrow pulses either from the  
input interface or from the output fault pulse generator  
and drives the appropriate high current switch.  
The 5V regulator provides power to the internal low  
voltage circuits that are referenced to VEE. Regulator  
is powered from V and V and its output voltage is  
CC  
EE  
referenced to V . An external bypass capacitor is  
EE  
required to provide the transient currents.  
3.1.11 Under Voltage and Over Voltage Lockout  
IX6611 contains an Under Voltage Lockout  
Comparator (UVLO COMP) and an Over Voltage  
Lockout Comparator (OVLO COMP). These  
comparators monitor the positive power supply

CC  
OVLO fault condition is communicated to the primary  
side by driving the FLT1 high current switch on the  
leading edge and the FLT2 high current switch on the  
trailing edge of the PWM gate drive ON cycle. The  
primary side recognizes the OVLO fault condition if  
and only if both FLT1 and FLT2 flags are set.  
beginning of each PWM cycle, if the difference in  
power supply voltage (V -V  
) is below the UVLO  
CC COM  
threshold or above the OVLO threshold the gate driver  
output is disabled (driven low) for that PWM cycle.  
Once the PWM cycle starts with no power supply  
faults then the gate driver is enabled and the UVLO  
and OVLO faults are ignored for the reminder of the  
cycle. Power supply fault are not latched. Normal  
operation resumes automatically on the next PWM  
input cycle after the power supply recovers from the  
fault condition.  
IGBT Over Current condition is communicated to the  
primary side by driving the FLT2 high current switch  
with a pulse from the output fault pulse generator.

4. Manufacturing Information  
4.1 Moisture Sensitivity  
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Corporation  
classified all of its plastic encapsulated devices for moisture sensitivity according to the  
latest version of the joint industry standard, IPC/JEDEC J-STD-020, in force at the time of product  
evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee  
proper operation of our devices when handled according to the limitations and information in that standard as well as  
to any limitations set forth in the information or standards referenced below.  
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced  
product performance, reduction of operable life, and/or reduction of overall reliability.  
This product carries a Moisture Sensitivity Level (MSL) classification as shown below, and should be handled  
according to the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.

4.4 Board Wash  
IXYS Corporation recommends the use of no-clean flux formulations. Board washing to reduce or  
remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to  
prevent damage to the device. These precautions include, but are not limited to: using a low pressure wash and  
providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing  
process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature  
and duration necessary to remove the moisture trapped within the package is the responsibility of the user  
(assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be  
used. Additionally, the device must not be exposed to flux or solvents that are Chlorine- or Fluorine-based.
