IRS26310DJPbF
Description
The IRS26310DJPBF is a high voltage, high speed power MOSFET and IGBT driver with three independent
high and low side referenced output channels for 3-phase applications. This IC is designed to be used with
low-cost bootstrap power supplies; the bootstrap diode functionality has been integrated into this device to
reduce the component count and the PCB size. Proprietary HVIC technology enables ruggedized monolithic
construction. Logic inputs are compatible with CMOS or LSTTL outputs, down to 3.3 V logic. A current trip
function which terminates all six outputs can be derived from an external current sense resistor. An enable
function is available to terminate all six outputs simultaneously. An open-drain FAULT signal is provided to
indicate that an overcurrent or a VCC undervoltage shutdown has occurred. Overcurrent fault conditions are
cleared automatically after a delay programmed externally via an RC network connected to the RCIN input.
The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction.
Propagation delays are matched to simplify use in high frequency applications. The floating channel can be
used to drive N-channel power MOSFETs or IGBTs in the high side configuration which operates up to 600 V.
A DCbus sensing is provided using an external divider. Over Voltage DCbus protection is activate when
DCbus exceed an externally adjustable threshold, activating zero-vector braking mode (all Low side output
turn-on, all High side output-turn-off).

Logic input to shutdown functionality. Logic functions when EN is high (i.e., positive logic). No
effect on FAULT and not latched.
Analog input for over-current shutdown. When active, ITRIP shuts down outputs and activates
FAULT and RCIN low. When ITRIP becomes inactive, FAULT stays active low for an externally
set time tFLTCLR, then automatically becomes inactive (open-drain high impedance).
Analog input for DCbus sensing
An external RC network input used to define the FAULT CLEAR delay (tFLTCLR) approximately

IGBT/MOSFET Gate Drive
The IRS26310D HVIC is designed to drive up to six 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.

Switching and Timing Relationships
The relationship between the input and output signals of the IRS26310D is illustrated below in Figures 3. From this
figure, we can see the definitions of several timing parameters (i.e., PWIN, PWOUT, tON, tOFF, tR, and tF) associated with
this device.
Figure 3: Switching time waveforms
The following two figures illustrate the timing relationships of some of the functionality of the IRS26310D; this
functionality is described in further detail later in this document.
During interval A of Figure 4, 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 4 and 5 shows that the signal on the ITRIP input pin has gone from a low to a high 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 input has returned to the low 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 4, 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 6 illustrates the deadtime period and the relationship
between the output gate signals.
The deadtime circuitry of the IRS26310D 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 6 defines the two deadtime
parameters (i.e., DT1 and DT2) of a specific channel; the deadtime matching parameter (MDT) associated with the
IRS26310D specifies the maximum difference between DT1 and DT2. The MDT parameter also applies when
comparing the DT of one channel of the IRS26310D to that of another.

Matched Propagation Delays
The IRS26310D family of HVICs 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 IRS26310D 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 IRS26310D has been designed to
be compatible with 3.3 V and 5 V logic-level signals. Figure 7 illustrates an input signal to the IRS26310D, its input
threshold values, and the logic state of the IC as a result of the input signal.

IRS26310DJPbF
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 8 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.

The IRS26310D is equipped with shoot-through protection circuitry (also known as cross-conduction prevention
circuitry). Figure 9 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 IRS26310D has non-inverting inputs (the output is in-phase with its respective input).

Enable Input
The IRS26310D 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
IRS26310D 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 10 illustrates the outputs’ response to a shutdown command.

Fault Reporting and Programmable Fault Clear Timer
The IRS26310D family provides an integrated fault reporting output and an adjustable fault clear timer. There are
two situations that would cause the HVIC to report a fault via the FAULT pin. The first is an undervoltage condition
of VCC and the second is if the ITRIP pin recognizes a fault. 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 11 where we see that a fault condition has
occurred (UVLO or ITRIP), RCIN and FAULT are pulled to VSS, and once the fault has been removed, the fault clear
timer begins. Figure 12 shows that RRCIN is connected between the VCC and the RCIN pin, while CRCIN is placed
between the RCIN and VSS pins.

Over-Current Protection
The IRS26310D HVICs are equipped with an ITRIP input pin. This functionality can be used to detect over-current
events in the DC- bus. Once the HVIC detects an over-current event through the ITRIP pin, 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 13: 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.
Over-Temperature Shutdown Protection
The ITRIP input of the IRS26310D 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 14 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
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 15; the OR-ing diodes have been labeled D1 and D2.

DC bus Over-Voltage Protection
When driving permanent magnet ac motors there is a potential to regenerate some of the motor mechanical
energy back onto the dc bus. “Zero vector braking” prevents charging of the dc bus capacitor by shorting all
three motor terminals to a common rail to dissipate this mechanical energy in the motor windings. The dc bus
over-voltage protection feature on the IC initiates zero vector braking when the dc bus voltage goes above some
critical voltage level to prevent damage to dc bus components. Zero vector braking should only be used when
the motor winding inductance is sufficient to limit the motor short circuit current to a safe level. Dc bus protection
operates even when all PWM inputs are disabled so will protect the motor when operating in high speed field
weakening mode.
The IRS26310D ICs have a DCbusSense input pin to detect over-voltage events on the DC bus. Once the IC
detects an over-voltage event, zero vector mode braking is forced (all Low side output turn-on, all High side
output-turn-off) overriding the PWM signals coming from the controller. A fault is not reported on the FAULT pin
for this condition because the power inverter is still active. DC bus over-voltage protection is not latched and so
the zero vector mode is released when DCbusSense pin is lower than OVDCBUSVTH- .
The level of voltage at which the over-voltage protection is initiated is determined by the resistor divider (i.e., R0 and
R1) connected to DCbusSense as shown in Figure 16, and the DCbusSense threshold (OVDCBUSVTH+). The circuit
designer will need to determine the maximum allowable level of DC bus voltage and select R0 and R1 such that the
voltage at node VX reaches the over-voltage threshold (OVDCBUSVTH+).

Truth Table: Undervoltage lockout, ITRIP, and ENABLE
Table 4 provides the truth table for the IRS26310D. 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
DCbus OV has been tripped and that the zero vector mode has been activated.
The third case shows that the UVLO for VBS has been tripped and that the high-side gate drive output has been
disabled. After VBS exceeds the VBSUV threshold, HO will stay low until the HVIC input receives a new or rising
transition of HIN. 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 (When ITRIP< VITRIP FAULT returns
to High impedance after RCIN pin becomes greater than 8V). In the fifth case, the HVIC has received a command
through the EN input to shutdown; as a result, the gate drive outputs have been disabled. The last case shows the
normal operation of the HVIC (a shoot-through protection prevention logic prevent LO1,2,3 and HO1,2,3 for each
channel turn on simultaneously).

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, and EN inputs. The working
principle of the new filter is shown in Figures 17 and 18.
Figure 17 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 18 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 17: Typical input filter
Figure 18: Advanced input filter
Short-Pulse / Noise Rejection
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 19 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 19 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.

Figure 19: Noise rejecting input filters
Figures 20 and 21 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 20; 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
20 shows the duration of PWIN, while the y-axis shows the resulting PWOUT duration. It can be seen that for a PWIN
duration less than tFIL,IN, that the resulting PWOUT duration is zero (e.g., the filter rejects the input signal/noise). We
also see that once the PWIN duration exceed tFIL,IN, that the PWOUT durations mimic the PWIN 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 PWOUT and PWIN signals of both the narrow ON and narrow OFF cases is shown in
Figure 21; the careful reader will note the scale of the y-axis. The x-axis of Figure 21 shows the duration of PWIN,
while the y-axis shows the resulting PWOUT–PWIN duration. This data illustrates the performance and near symmetry
of this input filter.

Integrated Bootstrap Functionality
The new IRS26310D family 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 22 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 23.
Figure 22: Internal bootstrap MOSFET connection
Figure 23: 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.

of the IRS26310, please refer to Application Note 1123 (AN-1123) entitled “Bootstrap Network Analysis: Focusing on
the Integrated Bootstrap Functionality.” This application note is available at www.irf.com.

please refer to Design Tip 04-4 (DT04-4) entitled “Using Monolithic High Voltage Gate Drivers.” This design tip is
available at www.irf.com.
Separate Logic and Power Grounds
The IRS26310D 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 24 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 25; here we define the power switches and diodes of the inverter.
If the high-side switch (e.g., the IGBT Q1 in Figures 26 and 27) 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 28 and 29), 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.

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 30 depicts one leg of the three phase inverter; Figures 31 and 32 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 30: Parasitic Elements
Figure 31: VS positive
Figure 32: 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 IRS26310D 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 IRS26310D’s performance can be seen in Figure 33. This experiment
was conducted using various loads to create this condition; the curve shown in this figure illustrates the successful
operation of the IRS26310D under these stressful conditions.

Figure 33: Negative VS transient results for an International Rectifier HVIC
Even though the IRS26310D 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 IRS26310D 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
34). 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 34: Antenna Loops

32
IRS26310DJPbF
Supply Capacitor: It is recommended to place a bypass capacitor (CIN) between the VCC and VSS pins. This
connection is shown in Figure 35. A ceramic 1 μF ceramic capacitor is suitable for most applications. This
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 37). See DT04-4
at www.irf.com for more detailed information.
