Description
The IR211(4,41)/IR221(4,41) 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 EM emissions. In multi-phase systems,
the IR211(4,41)/ IR221(4,41) drivers communicate using a dedicated local
network (SY_FLT and 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.

1 Features Description
1.1 Start-Up Sequence
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. All protection functions are
operating independently from the FLT_CLR status and
the output driver status reflects the input commands.
When the bootstrap supply topology is used for
supplying the floating high side stage, the following startup sequence is recommended (see also Fig. 12):
1. Set V
2. Set FLT_CLR pin to HIGH level,
3. Set LIN pin to HIGH level and charge the
4. Release LIN pin to LOW level,
5. Release FLT_CLR pin to LOW level.
A minimum 15 µs LIN and FLT-CLR pulse is required.
1.2 Normal Operation Mode
After the start-up sequence has completed, the device
becomes fully operative (see grey blocks in the State
Diagram).
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.
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 areor-ed so
the controller or one of the gate drivers can force the
simultaneous shutdown of the other gate drivers through
the same pin.

1.4 Fault Management
The IR211(4,41)/ IR221(4,41) is able to manage supply
failure (undervoltage lockout) and transistor desaturation
(on both the low and high side switches).
1.4.1 Undervoltage (UV)
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 (V
and the floating side (V
supplied) are controlled by a
BS
supplied)

An undervoltage event on the V

14). This event disables both the low side and floating

1.4.2 Power Devices Desaturation
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 IR211(4,41)/ IR221(4,41) fault detection circuit
monitors the IGBT emitter to collector voltage (V
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 condition results in an increase of V
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.
1.4.3 Desaturation Detection: DSH/L Function

sensing and soft shutdown block. This configuration is

The external sensing diode should have BV > 600 V or
1200 V and low stray capacitance (in order to minimize
noise coupling and switching delays). The diode is
biased by an internal pull-up resistor R
V

DS-
dedicated circuit (see the active-bias section for IR21141
and IR22141). When V
increases, the voltage at the
CE
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 V
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 t
are filtered out. To avoid
DS
detecting a false desaturation event during IGBT turn on,
the desaturation circuit is disabled by a blanking signal
(T
, see blanking block in Fig. 13). This time is the
BL
estimated maximum IGBT turn on time and must be not
exceeded by proper gate resistance sizing. When the
IGBT is not completely saturated after T
is detected and the driver will turn off.

Eligible desaturation signals initiate the SSD sequence.
While in SSD, the driver’s output goes to a high
impedance state and the SSD pull-down is activated to
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 (t
). Once
SS
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).
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.

Figure 15:
1.4.4 Fault Management in Multi-Phase Systems
In a system with two or more gate drivers the IR2214/1
devices must be connected as shown in Fig. 15.
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 (H
, LIN) they receive from the controller (freeze
IN
state). This feature is particularly important in phase-tophase 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.
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:
1. Desaturation detection event: the FAULT/SD
pin is
FLT_CLR signal can reset it,
2. Undervoltage on V
forced low and held until the undervoltage is
active (
3. FAULT/SD is externally driven low either from
the controller or from another IR2x14/1 device.
This event is
FLT_CLR cannot disable it. Only when
FAULT/SD becomes high the device returns to
its normal operating mode.
1.5 Active Bias
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 (V
transistor is “on” the diode is conducting and the amount
of current flowing in the circuit is determined by the
internal pull up resistor value.

In the high side circuit, the desaturation biasing current
may become relevant for dimensioning the bootstrap
capacitor (see Fig. 19). In fact, a pull up resistor with a
low resistance may result in a high current the
significantly discharges the bootstrap capacitor. For that
reason, the typical pull up resistor value is on the order
of 100 k. This is the value of the internal pull up.
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 applied
by the power transistor during the commutation at the
output results in a considerable current injected through
the stray capacitance of the diode into the desaturation
detection pin (DSH/DSL). This coupled noise may be
easily reduced be using an active bias structure for the
sensing diode.
An active bias structure is available only for the IR21141
or IR22141 versions. The DSH/DSL pins present an
active pull-up respectively to V

the DSH/DSL pinwhen the voltage exceeds the V
DESAT
threshold (see Fig. 16). This low impedance helps in
rejecting the noise provided by the current injected by
the parasitic capacitance. When the power transistor is
fully on, the sensing diode is forward biased and the
voltage at the DSH/DSL pin decreases. At this point the
biasing circuit deactivates, in order to reduce the bias
current of the diode as shown in Fig. 16.

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 (I
) and
O-
offers a low impedance path to prevent the self-turn on
due to the parasitic Miller capacitance in the power
switch.

2 Sizing Tips
2.1 Bootstrap Supply
The VBS voltage provides the supply to the high side
driver circuitry of the gate driver. This supply sits on top
of the V
voltage and so it must be floating. The
S
bootstrap method is used to generate the V
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.

This method has the advantage of being simple and low
cost but may force some limitations on duty-cycle and
on-time since they are limited by the requirement to
refresh the charge in the bootstrap capacitor. Proper
capacitor choice can reduce drastically these
limitations.
2.2 Bootstrap Capacitor Sizing

2.3 Some Important Considerations
Voltage Ripple: There are three different cases to
consider (refer to Fig. 19).

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 V

freewheeling diode is forwarded biased.

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

the current when the bootstrap capacitor is initially
charged. We suggest not exceeding 10 to avoid

Bootstrap Capacitor: For high
electrolytic capacitor is used, its ESR must be
considered. This parasitic resistance forms a voltage
divider with R
at the first charge of bootstrap capacitor. The voltage
step and the related speed (dV
As a general rule, ESR should meet the following
constraint.
A parallel combination of a small ceramic capacitor and
a large electrolytic capacitor is normally the best
compromise, the first capacitor posses a fast time
constant and limits the dV
equivalent resistance. The second capacitor provides a
large capacitance to maintain the V

2.4 Gate Resistances
The switching speed of the output transistor can be

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

NOTICE:
to approximate a way to size the gate resistance. A
more accurate sizing may provide more precise device
and PCB (parasitic) modelling.
The IR2x14/1 pin out 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 (V
side) while the other components are placed on the
V
S
opposite side.
3.2 Ground Plane
To minimize noise coupling, the ground plane must not
be placed under or near the high voltage floating side.
3.3 Gate Drive Loops
Current loops behave like antennas and are able to
receive and transmit EM noise. In order to reduce the
EM coupling and improve the power switch turn on/off
performances, gate drive loops must be reduced as
much as possible. Figure 23 shows the high and low
side gate loops.
Moreover, current can be injected inside the gate drive
loop via the IGBT collector-to-gate parasitic
capacitance. The parasitic auto-inductance of the gate
loop contributes to developing a voltage across the
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).

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).
