Description

The IR2114/IR2214 gate driver family is suited to drive a single half bridge in
power switching applications. These drivers provide high gate driving
capability (2 A source, 3 A sink) and require low quiescent current, which
allows the use of bootstrap power supply techniques in medium power
systems. These drivers feature full short circuit protection by means of power
transistor desaturation detection and manage all half-bridge faults by
smoothly turning off the desaturated transistor through the dedicated soft
shutdown pin, therefore preventing over-voltages and reducing
electromagnetic emissions. In multi-phase systems, the IR2114/IR2214
Package
drivers communicate using
a dedicated local network (SY_FLT and
24-Lead SSOP
FAULT/SD signals) to properly manage phase-to-phase short circuits. The
system controller may force shutdown or read device fault state through the
3.3 V compatible CMOS I/O pin (FAULT/SD). To improve the signal immunity
from DC-bus noise, the control and power ground use dedicated pins
enabling low-side emitter current sensing as well. Undervoltage conditions in
floating and low voltage circuits are managed independently.

†
While internal circuitry is operational below the indicated supply voltages, the UV lockout disables the output
drivers if the UV thresholds are not reached. A minimum supply voltage of 8V is recommended for the driver
to operate safely under switching conditions at VS pin (please refer to the “start-up sequence” in application
section of this document)
††
Logic operational for VS from VSS-5 V to VSS +600 V or 1200 V. Logic state held for VS from VSS -5 V to VSS-
VBS. For a negative spike on VB (referenced to VSS) of less than 200ns the IC will withstand a sustained peak
of -40V under normal operation and an isolated event of up to -70V peak spike (please refer to the Design
Tip DT97-3 for more details).

SY_FLT automatically resets after the SSD event is over, without requiring FLT_CLR to be asserted. To
avoid FLT_CLR conflicting with the SSD sequence of operations, in the event of a SSD during normal
operation it is recommended not to apply FLT_CLR while SY_FLT is active. At power supply start-up
instead, it is recommended to keep FLT_CLR active to prevent spurious diagnostic signals being
generated, as described in section 1.1 Start-Up Sequence and in section 1.4.5 Fault Management at
Start-up.
††
Holding FLT_CLR high all time will not allow the gate driver to latch the FAULT status and migth
compromise power system protection.

1.4 Fault Management
The IR2114/IR2214 is able to manage supply failure
(undervoltage lockout) and transistor desaturation (on
both the low and high side switches).
1 Features Description
1.1 Start-Up Sequence
1.4.1 Undervoltage (UV)
At power supply start-up, it is recommended to keep the
FLT_CLR pin active until the supply voltages are
properly established. This prevents spurious diagnostic
signals being generated.
The undervoltage protection function disables the
driver’s output stage which prevents the power device
from being driven when the input voltage is less than the
undervoltage threshold. Both the low side (VCC supplied)
and the floating side (VBS supplied) are controlled by a
dedicate undervoltage function.
When the bootstrap supply topology is used for
supplying the floating high side stage, the following start-
up sequence is recommended (see also Fig. 12):
An undervoltage event on the VCC pin (when
VCC < UVVCC-) generates a diagnostic signal by forcing
the FAULT/SD pin low (see FAULT/SD section and Fig.
14). This event disables both the low side and floating
drivers and the diagnostic signal holds until the
undervoltage condition is over. The fault condition is not
latched and the FAULT/SD pin is released once VCC
1. Set VCC
,
2. Set FLT_CLR pin to HIGH level,
3. Set LIN pin to HIGH level and charge the
bootstrap capacitor,
4. Release LIN pin to LOW level,
5. Release FLT_CLR pin to LOW level.
becomes higher than UVVCC+
.
VCC
FLT_CLR
LIN
The VBS undervoltage protection works by disabling only
the floating driver. Undervoltage on VBS does not prevent
the low side driver from activating its output nor does it
generate diagnostic signals. The VBS undervoltage
condition (VBS < UVVBS-) latches the high side output
stage in the low state. VBS must exceed the UVVBS+
threshold to return the device to its normal operating
mode. To turn on the floating driver, HIN must be re-
asserted high (rising edge event on HIN is required).

A minimum 15 µs LIN and FLT-CLR pulse is required.
A minimum supply voltage of 8V is recommended for the
driver to operate safely under switching conditions at VS
pin. At lower supply the gate driving capability decreases
and might become not sufficient to counteract switching
charge injected to the outputs.
Different causes can generate a power inverter failure
(phase and/or rail supply short-circuit, overload
conditions induced by the load, etc.). In all of these fault
conditions, a large increase in current results in the
IGBT.
The IR2114/IR2214 fault detection circuit monitors the
IGBT emitter to collector voltage (VCE) (an external high
voltage diode is connected between the IGBT’s collector
and the ICs DSH or DSL pins). A high current in the
IGBT may cause the transistor to desaturate; this

After the start-up sequence has completed, the device

Diagram).
condition results in an increase of VCE
.
HIN and LIN produce driver outputs to switch
accordingly, while the input logic monitors the input
signals and deadtime (DT) prevent shoot-through events
from occurring.
Once in desaturation, the current in the power transistor
can be as high as 10 times the nominal current.
Whenever the transistor is switched off, this high current
generates relevant voltage transients in the power stage
that need to be smoothed out in order to avoid
destruction (by over-voltage). The gate driver is able to
control the transient condition by smoothly turning off the
desaturated transistor with its integrated soft shutdown
(SSD) protection.
1.3 Shutdown
The system controller can asynchronously command the
Hard Shutdown (HSD) through the 3.3 V compatible
CMOS I/O FAULT/SD pin. This event is not latched.
In a multi-phase system, FAULT/SD signals are or-ed so
the controller or one of the gate drivers can force the
simultaneous shutdown of the other gate drivers through
the same pin.

Figure 13 shows the structure of the desaturation
sensing and soft shutdown block. This configuration is
the same for both the high and low side output stages.

turn off the IGBT through the SSDH/SSDL pin. The
SY_FLT output pin (active low, see Fig. 14) reports the
gate driver status during the SSD sequence (tSS). Once
the SSD has finished, SY_FLT releases, and the gate
driver generates a FAULT signal (see the FAULT/SD
section) by activating the FAULT/SD pin. This generates
a hard shutdown for both the high and low output stages
(HO=LO=low). Each driver is latched low until the fault is
cleared (see FLT_CLR).
series an external decoupling 1KΩ resistor is required in
order to limit the current flowing in and out of DSH and
DSL pins because of switching noise coupled through
the external de-saturation sensing diode. The diode is
biased by an internal pull-up resistor RDSH/L (equal to
VCC/IDS- or VBS/IDS-). When VCE increases, the voltage at
the DSH or DSL pin increases too. Being internally
biased to the local supply, the DSH/DSL voltage is
automatically clamped. When DSH/DSL exceeds the
VDESAT+ threshold, the comparator triggers (see Fig. 13).
The comparator’s output is filtered in order to avoid false
desaturation detection by externally induced noise;
pulses shorter than tDS are filtered out. To avoid
detecting a false desaturation event during IGBT turn on,
the desaturation circuit is disabled by a blanking signal
(TBL, see blanking block in Fig. 13). This time is the
estimated maximum IGBT turn on time and must be not
exceeded by proper gate resistance sizing. When the
IGBT is not completely saturated after TBL, desaturation
is detected and the driver will turn off.
Figure 14 shows the fault management circuit. In this
diagram DesatHS and DesatLS are two internal signals
that come from the output stages (see Fig. 13).
It must be noted that while in SSD, both the
undervoltage fault and external SD are masked until the
end of SSD. Desaturation protection is working
independently by the other control pin and it is disabled
only when the output status is off.
For the purpose of sensing the power transistor
desaturation, the collector voltage is monitored (an
external high voltage diode is connected between the
IGBT’s collector and the IC’s DSH or DSL pin). The
diode is normally biased by an internal pull up resistor
connected to the local supply line (VB or VCC). When the
transistor is “on” the diode is conducting and the amount
Eligible desaturation signals initiate the SSD sequence.

impedance state and the SSD pull-down is activated to

internal pull up resistor value.

order of 100 kΩ.
While the impedance of the DSH/DSL pins is very low
when the transistor is on (low impedance path through
the external diode down to the power transistor), the
impedance is only controlled by the pull up resistor when
the transistor is off. In that case, relevant dV/dt
generated at VS node might push the DSH/DSL pins
outside the recommended operating conditions.
1.4.5 Fault Management at Start-up
When the bootstrap supply topology is used for
supplying the floating high side and the recommended
power supply start-up sequence is followed, FLT_CLR
pin must be kept active to prevent spurious diagnostic
signals being generated.
1.4.4 Fault Management in Multi-Phase Systems
a system with two or more gate drivers the
In the event of power inverter failure already present or
occurring during start-up (phase and/or rail supply short-
circuit, overload conditions induced by the load, etc.),
keeping the FLT_CLR pin active will also prevent the
real fault condition to be detected with the FAULT/SD
pin. In such a condition a large current increase in the
IGBT will desaturate the transistor, allowing the gate
driver to detect and turn-off the desaturated transistor
with the integrated soft shutdown (SSD) protection.
As with a normal SSD sequence, during SSD the
SY_FLT output pin (active low, see Fig. 14) will report
the gate driver status. But now, being the FLT_CLR pin
already active, the gate driver will not generate a FAULT
signal by activating the FAULT/SD pin and it will not
enter hard shutdown.

To prevent the driver to resume charging the bootstrap
capacitor, therefore re-establishing the condition that will
determine again the occurrence of the large current
increase in the IGBT, it is recommended to monitor the
SY_FLT output pin. Should the SY_FLT output pin go
low during the start-up sequence, the controller must
interpret a power inverter failure is present, and stop the
start-up sequence.

SY_FLT: The bi-directional SY_FLT pins communicate
each other through a local network. The logic signal is
active low. The device that detects the IGBT
desaturation activates the SY_FLT, which is then read
by the other gate drivers. When SY_FLT is active all the
drivers hold their output state regardless of the input
signals (HIN, LIN) they receive from the controller (freeze
state). This feature is particularly important in phase-to-
phase short circuit where two IGBTs are involved; in
fact, while one is softly shutting-down, the other must be
prevented from hard shutdown to avoid exiting SSD. In
the freeze state, the frozen drivers are not completely
inactive because desaturation detection still takes the
highest priority. SY_FLT communication has been
designed for creating a local network between the
drivers. There is no need to wire SY_FLT to the
controller.
1.6 Output Stage
The structure is shown in Fig. 13 and consists of two
turn on stages and one turn off stage. When the driver
turns on the IGBT (see Fig. 8), a first stage is activated
while an additional stage is maintained in the active state
for a limited time (ton1). This feature boosts the total
driving capability in order to accommodate both a fast
gate charge to the plateau voltage and dV/dt control in
switching.
At turn off, a single n-channel sinks up to 3 A (IO-) and
offers a low impedance path to prevent the self-turn on
due to the parasitic Miller capacitance in the power
switch.
FAULT/SD:
The
bi-directional
FAULT/SD
pins
communicate with each other and with the system
controller. The logic signal is active low. When low, the
FAULT/SD signal commands the outputs to go off by
hard shutdown. There are three events that can force
FAULT/SD low:

The VBS voltage provides the supply to the high side

of the VS voltage and so it must be floating. The
bootstrap method is used to generate the VBS supply
and can be used with any of the IR211(4,41)/
IR221(4,41) drivers. The bootstrap supply is formed by
a diode and a capacitor as connected in Fig. 19.
ILK_CAP is only relevant when using an electrolytic
capacitor and can be ignored if other types of
capacitors are used. It is strongly recommend using at
least one low ESR ceramic capacitor (paralleling
electrolytic and low ESR ceramic may result in an
efficient solution).

2.2 Bootstrap Capacitor Sizing
To size the bootstrap capacitor, the first step is to
establish the minimum voltage drop (∆VBS) that we
have to guarantee when the high side IGBT is on.
And:
If VGEmin is the minimum gate emitter voltage we want
to maintain, the voltage drop must be:
•
VCC = 15 V
VF = 1 V
•
•
•
VCEonmax = 3.1 V
VGEmin = 10.5 V
∆VBS ≤ VCC −VF −VGE min −VCEon
under the condition,
the maximum voltage drop ∆VBS becomes
VGE min > VBSUV −
∆VBS ≤VCC −VF −VGEmin −VCEon
=
where VCC is the IC voltage supply, VF is bootstrap
diode forward voltage, VCEon is emitter-collector voltage
of low side IGBT, and VBSUV- is the high-side supply
undervoltage negative going threshold.
And the bootstrap capacitor is:
Now we must consider the influencing factors

bootstrap capacitor to VCC supply.
2.3 Some Important Considerations
Voltage Ripple: There are three different cases to
consider (refer to Fig. 19).
2.4 Gate Resistances
The switching speed of the output transistor can be
controlled by properly sizing the resistors controlling the
turn-on and turn-off gate currents. The following section
provides some basic rules for sizing the resistors to
obtain the desired switching time and speed by
introducing the equivalent output resistance of the gate
driver (RDRp and RDRn).
ꢀ
ILOAD < 0 A; the load current flows in the low side
IGBT (resulting in VCEon).
VBS = VCC −VF −VCEon
In this case we have the lowest value for VBS. This
represents the worst case for the bootstrap capacitor
sizing. When the IGBT is turned off, the Vs node is
pushed up by the load current until the high side
freewheeling diode is forwarded biased.
The example shown uses IGBT power transistors and
Figure 20 shows the nomenclature used in the following
paragraphs. In addition, Vge indicates the plateau

In this case we have the highest value for VBS. Turning

bootstrap capacitor should be sized according to the
ILOAD< 0 A case.

2.5 Sizing The Turn-On Gate Resistor
Bootstrap Capacitor: For high tHON designs where an
electrolytic capacitor is used, its ESR must be
considered. This parasitic resistance forms a voltage
divider with Rboot, which generats a voltage step on VBS
at the first charge of bootstrap capacitor. The voltage
step and the related speed (dVBS/dt) should be limited.
As a general rule, ESR should meet the following
constraint.
Switching-Time: For the matters of the calculation
included hereafter, the switching time tsw is defined
as the time spent to reach the end of the plateau
voltage (a total Qgc+Qge has been provided to the
IGBT gate). To obtain the desired switching time the

3 PCB Layout Tips
3.5 Routing and Placement Example
3.1 Distance from High to Low Voltage
Figure 24 shows one of the possible layout solutions
using a 3 layer PCB. This example takes into account
all the previous considerations. Placement and routing
for supply capacitors and gate resistances in the high
and low voltage side minimize the supply path loop and
the gate drive loop. The bootstrap diode is placed under
the device to have the cathode as close as possible to
the bootstrap capacitor and the anode far from high
The IR2x14x pinout maximizes the distance between
floating (from DC- to DC+) and low voltage pins. It’s
strongly recommended to place components tied to
floating voltage on the high voltage side of device (VB,
VS side) while the other components are placed on the
opposite side.

Current loops behave like antennas and are able to
receive and transmit EM noise. In order to reduce the

much as possible. Figure 23 shows the high and low

Moreover, current can be injected inside the gate drive

gate-emitter, increasing the possibility of self turn-on.
For this reason, it is strongly recommended to place the
three gate resistances close together and to minimize
the loop area (see Fig. 23).

Figure 24: layout example
The IR2x14x output stages are able to quickly turn on
an IGBT, with up to 2 A of output current. The supply
capacitors must be placed as close as possible to the
device pins (VCC and VSS for the ground tied supply, VB
and VS for the floating supply) in order to minimize
parasitic inductance/resistance.

IR2114/IR2214SSPbF
Figures 25-83 provide information on the experimental performance of the IR2114/IR2214SSPbF HVIC. The line plotted
in each figure is generated from actual lab data. A large number of individual samples from multiple wafer lots were
tested at three temperatures (-40 ºC, 25 ºC, and 125 ºC) in order to generate the experimental (Exp.) curve. The line
labeled Exp. consist of three data points (one data point at each of the tested temperatures) that have been connected
together to illustrate the understood trend. The individual data points on the curve were determined by calculating the
averaged experimental value of the parameter (for a given temperature).
