Description
The IRS26302DJPBF are high voltage, high speed power MOSFET and IGBT drivers with three independent high
and low side referenced output channels for 3-phase applications. An additional low side driver is included for PFC
or Brake IGBT driving operation. Proprietary HVIC technology enables rugged monolithic construction. Logic inputs
are compatible with CMOS or LSTTL outputs, down to 3.3V logic. Three current trip functions that terminate all
seven outputs can be derived from three external shunt resistors. Each overcurrent trip functions consists of
detecting excess current across a shunt resistor on DC+ bus, on DC- bus and on Brake or PFC circuitry. An enable
function is available to terminate all outputs simultaneously and is provided through a bidirectional pin combined
with an open-drain FAULT pin. Fault signal is provided to indicate that an overcurrent or undervoltage shutdown
has occurred. Overcurrent fault conditions are cleared automatically after an externally programmed delay via an
RC network connected to the RCIN input. A diagnostic feature can give back to the controller the fault cause
(UVcc, DC- or DC- overcurrent) and address a fault register. The output drivers feature a high pulse current buffer
stage. Propagation delays are matched to simplify use in high frequency applications designed for minimum driver
cross conduction. The floating channel can be used to drive N-channel power MOSFET’s or IGBT’s in the high
side configuration which operates up to 600 V.

IGBT/MOSFET Gate Drive
The IRS26302DJ HVICs are designed to drive MOSFET or IGBT power devices. Figures 1 and 2 illustrate several
parameters associated with the gate drive functionality of the HVIC. The output current of the HVIC, used to drive the
gate of the power switch, is defined as IO. The voltage that drives the gate of the external power switch is defined as
VHO for the high-side power switch and VLO for the low-side power switch; this parameter is sometimes generically
called VOUT and in this case does not differentiate between the high-side or low-side output voltage.

The relationship between the input and output signals of the IRS26302DJ are illustrated below in Figures 3. From
this figure, we can see the definitions of several timing parameters (i.e., PW IN, PW OUT, tON, tOFF, tR, and tF) associated

Figure 3: Switching time waveforms
The following two figures illustrate the timing relationships of some of the functionality of the IRS26302DJ; this
functionality is described in further detail later in this document.
During interval A of Figure 5, the HVIC has received the command to turn-on both the high- and low-side switches at
the same time; as a result, the shoot-through protection of the HVIC has prevented this condition and both the highand low-side output are held in the off state.
Interval B of Figures 5 and 6 shows that the signal on the ITRIP, GF, PCFtrip input pin has gone from a not active to
an active state; as a result, all of the gate drive outputs have been disabled (i.e., see that HOx has returned to the low
state; LOx is also held low), the voltage on the RCIN pin has been pulled to 0 V, and a fault is reported by the FAULT
output transitioning to the low state. Once the ITRIP, GF, PCFtrip input has returned to the not active state, the
output will remain disabled and the fault condition reported until the voltage on the RCIN pin charges up to VRCIN,TH
(see interval C in Figure 6); the charging characteristics are dictated by the RC network attached to the RCIN pin.
During intervals D and E of Figure 5, we can see that the enable (EN) pin has been pulled low (as is the case when
the driver IC has received a command from the control IC to shutdown); this results in the outputs (HOx and LOx)
being held in the low state until the enable pin is pulled high.

Deadtime
This family of HVICs features integrated deadtime protection circuitry. The deadtime for these ICs is fixed; other ICs
within IR’s HVIC portfolio feature programmable deadtime for greater design flexibility. The deadtime feature inserts
a time period (a minimum deadtime) in which both the high- and low-side power switches are held off; this is done to
ensure that the power switch being turned off has fully turned off before the second power switch is turned on. This
minimum deadtime is automatically inserter whenever the external deadtime is shorter than DT; external deadtimes
larger than DT are not modified by the gate driver. Figure 7 illustrates the deadtime period and the relationship
between the output gate signals.
The deadtime circuitry of the IRS26302DJ is matched with respect to the high- and low-side outputs of a given
channel; additionally, the deadtimes of each of the three channels are matched. Figure 7 defines the two deadtime
parameters (i.e., DT1 and DT2) of a specific channel; the deadtime matching parameter (MDT) associated with the
IRS26302DJ specifies the maximum difference between DT1 and DT2. The MDT parameter also applies when
comparing the DT of one channel of the IRS26302DJ to that of another.

Matched Propagation Delays
The IRS26302DJ is designed with propagation delay matching circuitry. With this feature, the IC’s response at the
output to a signal at the input requires approximately the same time duration (i.e., tON, tOFF) for both the low-side
channels and the high-side channels; the maximum difference is specified by the delay matching parameter (MT).
Additionally, the propagation delay for each low-side channel is matched when compared to the other low-side
channels and the propagation delays of the high-side channels are matched with each other; the MT specification
applies as well. The propagation turn-on delay (tON) of the IRS26302DJ is matched to the propagation turn-on delay
(tOFF).
Input Logic Compatibility
The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS26302DJ has been designed to
be compatible with 3.3 V and 5 V logic-level signals. Figure 8 illustrates an input signal to the IRS26302DJ, its input
threshold values, and the logic state of the IC as a result of the input signal.

Undervoltage Lockout Protection
This family of ICs provides undervoltage lockout protection on both the VCC (logic and low-side circuitry) power supply
and the VBS (high-side circuitry) power supply. Figure 9 is used to illustrate this concept; VCC (or VBS) is plotted over
time and as the waveform crosses the UVLO threshold (VCCUV+/- or VBSUV+/-) the undervoltage protection is enabled or
disabled.
Upon power-up, should the VCC voltage fail to reach the VCCUV+ threshold, the IC will not turn-on. Additionally, if the
VCC voltage decreases below the VCCUV- threshold during operation, the undervoltage lockout circuitry will recognize a
fault condition and shutdown the high- and low-side gate drive outputs, and the FAULT pin will transition to the low
state to inform the controller of the fault condition.
Upon power-up, should the VBS voltage fail to reach the VBSUV threshold, the IC will not turn-on. Additionally, if the VBS
voltage decreases below the VBSUV threshold during operation, the undervoltage lockout circuitry will recognize a fault
condition, and shutdown the high-side gate drive outputs of the IC.
The UVLO protection ensures that the IC drives the external power devices only when the gate supply voltage is
sufficient to fully enhance the power devices. Without this feature, the gates of the external power switch could be
driven with a low voltage, resulting in the power switch conducting current while the channel impedance is high; this
could result in very high conduction losses within the power device and could lead to power device failure.
Figure 9: UVLO protection
Shoot-Through Protection
The IRS26302DJ is equipped with shoot-through protection circuitry (also known as cross-conduction prevention
circuitry). Figure 10 shows how this protection circuitry prevents both the high- and low-side switches from
conducting at the same time. Table 1 illustrates the input/output relationship of the devices in the form of a truth
table. Note that the IRS26302DJ has non-inverting inputs (the output is in-phase with its respective input).

Enable Input
The IRS26302DJ is equipped with an enable input pin that is used to shutdown or enable the HVIC. When the EN
pin is in the high state the HVIC is able to operate normally (assuming no other fault conditions). When a condition
occurs that should shutdown the HVIC, the EN pin should see a low logic state. The enable circuitry of the
IRS26302DJ features an input filter; the minimum input duration is specified by tFILTER,EN. Please refer to the EN pin
parameters VEN,TH+, VEN,TH-, and IEN for the details of its use. Table 2 gives a summary of this pin’s functionality and
Figure 11 illustrates the outputs’ response to a shutdown command.

Fault Reporting and Programmable Fault Clear Timer
The IRS26302DJ provides an integrated fault reporting output and an adjustable fault clear timer. There are several
situations that would cause the HVIC to report a fault via the FAULT pin: an undervoltage condition of VCC or ITRIP,
Ground Fault (GF), PCFtrip pin recognizes an overcurrent. Once the fault condition occurs, the FAULT pin is
internally pulled to VSS and the fault clear timer is activated. The fault output stays in the low state until the fault
condition has been removed and the fault clear timer expires; once the fault clear timer expires, the voltage on the
FAULT pin will return to VCC.
The length of the fault clear time period (tFLTCLR) is determined by exponential charging characteristics of the capacitor
where the time constant is set by RRCIN and CRCIN. In Figure 12 where we see that a fault condition has occurred
(ITRIP), RCIN and FAULT are pulled to VSS, and once the fault has been removed, the fault clear timer begins.
Figure 13 shows that RRCIN is connected between the VCC and the RCIN pin, while CRCIN is placed between the RCIN
and VSS pins.

The length of the fault clear time period can be determined by using the formula below.

vC(t) = Vf(1-e
)
tFLTCLR = -(RRCINCRCIN)ln(1-VRCIN,TH/VCC)
Over-Current Protections
The IRS26302DJ HVICs are equipped with an ITRIP, GF and PFCtrip input pin. These functionality can be used to
detect over-current events in the DC- bus, in the DC+ bus, in the PFC section and Ground related. Once the HVIC
detects an over-current event, the outputs are shutdown, a fault is reported through the FAULT pin, and RCIN is
pulled to VSS.
The level of current at which the over-current protection is initiated is determined by the resistor network (i.e., R0, R1,
and R2) connected to ITRIP as shown in Figure 14, and the ITRIP threshold (VIT,TH+). The circuit designer will need to
determine the maximum allowable level of current in the DC- bus and select R0, R1, and R2 such that the voltage at
node VX reaches the over-current threshold (VIT,TH+) at that current level.
VIT,TH+ = R0IDC-(R1/(R1+R2))
Figure 14: Programming the over-current protection
For example, a typical value for resistor R0 could be 50 mΩ. The voltage of the ITRIP pin should not be allowed to
exceed 5 V; if necessary, an external voltage clamp may be used.
The shunt resistor or resistor network for GF or PCFtrip can be determined according to GF, PCFtrip threshold and
level of protection current. The GF pin should not be outside this range (VDC+0.3V, VDC-5V) and PCFtrip should not
be outside (Vcc+0.3V, Vss-5V); if necessary, an external voltage clamp may be used.
Over-Temperature Shutdown Protection
The ITRIP input of the IRS26302DJ can also be used to detect over-temperature events in the system and initiate a
shutdown of the HVIC (and power switches) at that time. In order to use this functionality, the circuit designer will
need to design the resistor network as shown in Figure 15 and select the maximum allowable temperature.
This network consists of a thermistor and two standard resistors R3 and R4. As the temperature changes, the
resistance of the thermistor will change; this will result in a change of voltage at node VX. The resistor values should

IRS26302DJ
be selected such the voltage VX should reach the threshold voltage (VIT,TH+) of the ITRIP functionality by the time that
the maximum allowable temperature is reached. The voltage of the ITRIP pin should not be allowed to exceed 5 V.
When using both the over-current protection and over-temperature protection with the ITRIP input, OR-ing diodes
(e.g., DL4148) can be used. This network is shown in Figure 16; the OR-ing diodes have been labeled D1 and D2.

Truth Table: Undervoltage lockout, ITRIP, GF, PCFtrip and ENABLE
Table 4 provides the truth table for the IRS26302DJ. The first line shows that the UVLO for VCC has been tripped; the
FAULT output has gone low and the gate drive outputs have been disabled. VCCUV is not latched in this case and
when VCC is greater than VCCUV, the FAULT output returns to the high impedance state.
The second case shows that the UVLO for VBS has been tripped and that the high-side gate drive outputs have been
disabled. After VBS exceeds the VBSUV threshold, HO will stay low until the HVIC input receives a new rising transition
of HIN. The third case shows the normal operation of the HVIC. The fourth case illustrates that the ITRIP trip
threshold has been reached and that the gate drive outputs have been disabled and a fault has been reported
through the fault pin. Same behavior if GF or PCFtrip threshold has been reached. In the last case, the HVIC has
received a command through the EN input to shutdown; as a result, the gate drive outputs have been disabled.

Fault Diagnostic: DIAG STATE –State Diagram
After each fault event a diagnostic feature, if enable, can communicate to the controller which fault happened in the
system (UVcc, ITRIP, GF, PCFtrip). If diagnostic is enabled forcing all HIN and all LIN = High the HVIC enters in
handshake mode, all the outputs remain off, the automatic fault clear function is disabled and FLT/EN is in HZ (refer to
Figure 17 for more details). The HVIC fault register is now ready for queries. A procedure to interrogate the fault register
is depicted in the fault query routine (Figure 18).

Advanced Input Filter
The advanced input filter allows an improvement in the input/output pulse symmetry of the HVIC and helps to reject
noise spikes and short pulses. This input filter has been applied to the HIN, LIN, PFCin and EN inputs. The working
principle of the new filter is shown in Figures 19 and 20.
Figure 19 shows a typical input filter and the asymmetry of the input and output. The upper pair of waveforms
(Example 1) show an input signal with a duration much longer then tFIL,IN; the resulting output is approximately the
difference between the input signal and tFIL,IN. The lower pair of waveforms (Example 2) show an input signal with a
duration slightly longer then tFIL,IN; the resulting output is approximately the difference between the input signal and
tFIL,IN.
Figure 20 shows the advanced input filter and the symmetry between the input and output. The upper pair of
waveforms (Example 1) show an input signal with a duration much longer then tFIL,IN; the resulting output is
approximately the same duration as the input signal. The lower pair of waveforms (Example 2) show an input signal
with a duration slightly longer then tFIL,IN; the resulting output is approximately the same duration as the input signal.
Figure 19: Typical input filter
Figure 20: Advanced input filter
Short-Pulse / Noise Rejection
Example 2
Example 1
This device’s input filter provides protection against short-pulses (e.g., noise) on the input lines. If the duration of the
input signal is less than tFIL,IN, the output will not change states. Example 1 of Figure 21 shows the input and output in
the low state with positive noise spikes of durations less than tFIL,IN; the output does not change states. Example 2 of
Figure 21 shows the input and output in the high state with negative noise spikes of durations less than tFIL,IN; the
output does not change states.

Figures 22 and 23 present lab data that illustrates the characteristics of the input filters while receiving ON and OFF
pulses.
The input filter characteristic is shown in Figure 22; the left side illustrates the narrow pulse ON (short positive pulse)
characteristic while the left shows the narrow pulse OFF (short negative pulse) characteristic. The x-axis of Figure 22
shows the duration of PW IN, while the y-axis shows the resulting PW OUT duration. It can be seen that for a PW IN
duration less than tFIL,IN, that the resulting PW OUT duration is zero (e.g., the filter rejects the input signal/noise). We
also see that once the PW IN duration exceed tFIL,IN, that the PW OUT durations mimic the PW IN durations very well over
this interval with the symmetry improving as the duration increases. To ensure proper operation of the HVIC, it is
suggested that the input pulse width for the high-side inputs be ≥ 500 ns.
Time (ns)
The difference between the PW OUT and PW IN signals of both the narrow ON and narrow OFF cases is shown in
Figure 23; the careful reader will note the scale of the y-axis. The x-axis of Figure 21 shows the duration of PW IN,
while the y-axis shows the resulting PW OUT–PW IN duration. This data illustrates the performance and near symmetry
of this input filter.

IRS26302DJ
Integrated Bootstrap Functionality
The IRS26302DJ features integrated high-voltage bootstrap MOSFETs that eliminate the need of the external
bootstrap diodes and resistors in many applications.
There is one bootstrap MOSFET for each high-side output channel and it is connected between the VCC supply and
its respective floating supply (i.e., VB1, VB2, VB3); see Figure 24 for an illustration of this internal connection.
The integrated bootstrap MOSFET is turned on only during the time when LO is ‘high’, and it has a limited source
current due to RBS. The VBS voltage will be charged each cycle depending on the on-time of LO and the value of the
CBS capacitor, the drain-source (collector-emitter) drop of the external IGBT (or MOSFET), and the low-side freewheeling diode drop.
The bootstrap MOSFET of each channel follows the state of the respective low-side output stage (i.e., the bootstrap
MOSFET is ON when LO is high, it is OFF when LO is low), unless the VB voltage is higher than approximately 110%
of VCC. In that case, the bootstrap MOSFET is designed to remain off until VB returns below that threshold; this
concept is illustrated in Figure 25.

Figure 24: Internal bootstrap MOSFET connection
Figure 25: Bootstrap MOSFET state diagram
A bootstrap MOSFET is suitable for most of the PWM modulation schemes and can be used either in parallel with the
external bootstrap network (i.e., diode and resistor) or as a replacement of it. The use of the integrated bootstrap as
a replacement of the external bootstrap network may have some limitations. An example of this limitation may arise
when this functionality is used in non-complementary PWM schemes (typically 6-step modulations) and at very high
PWM duty cycle. In these cases, superior performances can be achieved by using an external bootstrap diode in
parallel with the internal bootstrap network.

Separate Logic and Power Grounds
The IRS26302DJ has separate logic and power ground pin (VSS and COM respectively) to eliminate some of the
noise problems that can occur in power conversion applications. Current sensing shunts are commonly used in many
applications for power inverter protection (i.e., over-current protection), and in the case of motor drive applications, for
motor current measurements. In these situations, it is often beneficial to separate the logic and power grounds.
Figure 26 shows a HVIC with separate VSS and COM pins and how these two grounds are used in the system. The
VSS is used as the reference point for the logic and over-current circuitry; VX in the figure is the voltage between the
ITRIP pin and the VSS pin. Alternatively, the COM pin is the reference point for the low-side gate drive circuitry. The
output voltage used to drive the low-side gate is VLO-COM; the gate-emitter voltage (VGE) of the low-side switch is the
output voltage of the driver minus the drop across RG,LO.

Tolerant to Negative VS Transients
A common problem in today’s high-power switching converters is the transient response of the switch node’s voltage
as the power switches transition on and off quickly while carrying a large current. A typical 3-phase inverter circuit is
shown in Figure 27; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 28 and 29) switches off, while the U phase current is flowing to
an inductive load, a current commutation occurs from high-side switch (Q1) to the diode (D2) in parallel with the lowside switch of the same inverter leg. At the same instance, the voltage node VS1, swings from the positive DC bus
voltage to the negative DC bus voltage.

Also when the V phase current flows from the inductive load back to the inverter (see Figures 30 and 31), and Q4
IGBT switches on, the current commutation occurs from D3 to Q4. At the same instance, the voltage node, VS2,
swings from the positive DC bus voltage to the negative DC bus voltage.
Figure 30: D3 conducting
Figure 31: Q4 conducting
However, in a real inverter circuit, the VS voltage swing does not stop at the level of the negative DC bus, rather it
swings below the level of the negative DC bus. This undershoot voltage is called “negative VS transient”.
The circuit shown in Figure 32 depicts one leg of the three phase inverter; Figures 33 and 34 show a simplified
illustration of the commutation of the current between Q1 and D2. The parasitic inductances in the power circuit from
the die bonding to the PCB tracks are lumped together in LC and LE for each IGBT. When the high-side switch is on,

VS1 is below the DC+ voltage by the voltage drops associated with the power switch and the parasitic elements of the
circuit. When the high-side power switch turns off, the load current momentarily flows in the low-side freewheeling
diode due to the inductive load connected to VS1 (the load is not shown in these figures). This current flows from the
DC- bus (which is connected to the COM pin of the HVIC) to the load and a negative voltage between VS1 and the
DC- Bus is induced (i.e., the COM pin of the HVIC is at a higher potential than the VS pin).
Figure 32: Parasitic Elements
Figure 33: VS positive
Figure 34: VS negative
In a typical motor drive system, dV/dt is typically designed to be in the range of 3-5 V/ns. The negative VS transient
voltage can exceed this range during some events such as short circuit and over-current shutdown, when di/dt is
greater than in normal operation.
International Rectifier’s HVICs have been designed for the robustness required in many of today’s demanding
applications. The IRS26302DJ has been seen to withstand large negative VS transient conditions on the order of -50
V for a period of 50 ns. An illustration of the IRS26302DJ’s performance can be seen in Figure 35. This experiment
was conducted using various loads to create this condition; the curve shown in this figure illustrates the successful
operation of the IRS26302DJ under these stressful conditions. In case of -VS transients greater then -20 V for a
period of time greater than 100 ns; the HVIC is designed to hold the high-side outputs in the off state for 4.5 µs in
order to ensure that the high- and low-side power switches are not on at the same time.
Figure 35: Negative VS transient results for an International Rectifier HVIC
Even though the IRS26302DJ has been shown able to handle these large negative VS transient conditions, it is highly
recommended that the circuit designer always limit the negative VS transients as much as possible by careful PCB
layout and component use.

PCB Layout Tips
Distance between high and low voltage components: It’s strongly recommended to place the components tied to the
floating voltage pins (VB and VS) near the respective high voltage portions of the device. The IRS26302DJ in the
PLCC44 package has had some unused pins removed in order to maximize the distance between the high voltage
and low voltage pins. Please see the Case Outline PLCC44 information in this datasheet for the details.
Ground Plane: In order to minimize noise coupling, the ground plane should not be placed under or near the high
voltage floating side.
Gate Drive Loops: Current loops behave like antennas and are able to receive and transmit EM noise (see Figure
36). In order to reduce the EM coupling and improve the power switch turn on/off performance, the gate drive loops
must be reduced as much as possible. 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, thus increasing the possibility of a self turn-on effect.
Figure 36: Antenna Loops
Supply Capacitor: It is recommended to place a bypass capacitor (CIN) between the VCC and VSS pins.
connection is shown in Figure 37. A ceramic 1 µF ceramic capacitor is suitable for most applications.
component should be placed as close as possible to the pins in order to reduce parasitic elements.

Routing and Placement: Power stage PCB parasitic elements can contribute to large negative voltage transients at
the switch node; it is recommended to limit the phase voltage negative transients. In order to avoid such conditions, it
is recommended to 1) minimize the high-side emitter to low-side collector distance, and 2) minimize the low-side
emitter to negative bus rail stray inductance. However, where negative VS spikes remain excessive, further steps
may be taken to reduce the spike. This includes placing a resistor (5 Ω or less) between the VS pin and the switch
node (see Figure 36), and in some cases using a clamping diode between VSS and VS (see Figure 39). See DT04-4
at www.irf.com for more detailed information.

Parameter Temperature Trends
Figures 40-115 provide information on the experimental performance of the IRS26302DJ HVIC. The line
plotted in each figure is generated from actual lab data. A large number of individual samples 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).
