AUIRS2334S

Description

The AUIRS2334S is a high voltage, high speed power MOSFET and IGBT driver with three independent high

side and low side referenced output channels for 3-phase applications. Proprietary HVIC and latch immune

CMOS technology enables ruggedized monolithic construction. Logic inputs are compatible with CMOS or

LSTTL outputs, down to 3.3 V. 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 up to 600 V.

IGBT/MOSFET Gate Drive

The AUIRS2334 HVIC is designed to drive high side and low side MOSFET or IGBT power devices. Figures 1

and 2 show the definition of some of the relevant parameters associated with the gate driver output functionality.

The output current that drives the gate of the external power switches is defined as I_O. The output voltage that

drives the gate of the external power switches is defined as V_HOfor the high side and V_LOfor the low side; this

parameter is sometimes generically called V_OUTand in this case the high side and low side output voltages are

not differentiated.

Deadtime

The AUIRS2334 HVIC provides an integrated deadtime protection circuitry. The deadtime interval for this HVIC is

fixed; while other ICs within IR‘s HVIC portfolio feature programmable deadtime for greater design flexibility. The

deadtime feature inserts a time interval in which both the gate driver outputs LO and HO are held off; 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 inserted whenever the external deadtime commanded by the host

microcontroller is shorter than DT, while external deadtimes larger than DT are not modified by the gate driver.

Figure 7 illustrates the deadtime interval definition and the relationship between the output gate signals.

The deadtime interval introduced is matched with respect to the commutation from HIN turning off to LIN turning

on, and viceversa. Figure 5 defines the two deadtime parameters DT1 and DT2. The deadtime matching

parameter MDT is defined as the maximum difference between DT1 and DT2.

Under-Voltage Lockout Protection

The AUIRS2334 HVIC provides under-voltage lockout protection on both the V_CClow side and logic fixed power

supply and the VBS high side floating power supply. Figure 8 illustrates this concept by considering the V_CC(or

V_BS) plotted over time: as the waveform crosses the UVLO threshold, the under-voltage protection is entered or

exited.

Upon power up, should the V_CCvoltage fail to reach the V_CCUV+threshold, the gate driver outputs LO and HO will

remain disabled. Additionally, if the V_CCvoltage decreases below the V_CCUV-threshold during normal operation,

the under-voltage lockout circuitry will shutdown the gate driver outputs LO and HO.

Upon power up, should the V_BSvoltage fail to reach the V_BSUVthreshold, the gate driver output HO will remain

disabled. Additionally, if the V_BSvoltage decreases below the V_BSUVthreshold during normal operation, the under-

voltage lockout circuitry will shutdown the high side gate driver output HO.

The UVLO protection ensures that the HVIC drives external power devices only with a gate supply voltage

sufficient to fully enhance them. Without this protection, the gates of the external power switches could be driven

with a low voltage, which would result in power switches conducting current while with a high channel impedance,

which would produce very high conduction losses possibly leading to power device failure.

Advanced Input Filter

The AUIRS2334 HVIC provides an advanced input filter that improves the input/output pulse symmetry of the

signals processed by the HVIC. This input filter is inserted at the HIN and LIN input pins. The working principle of

the filter is shown in Figures 9 and 10.

Figure 9 shows a typical input filter and the asymmetry it produces on its output signal. The upper waveforms of

Example 1 show an input signal with a pulse duration mush longer than the filtering time t_FILIN; the resulting output

AUIRS2334S

signal has a duration given approximately by the difference between the input signal and t_FILIN. The lower

waveforms of Example 2 show an input signal with a pulse duration slightly longer than the filtering time t_FILIN; the

resulting output signal has a duration given approximately by the difference between the input signal and t_FILIN,

much shorter than it should be.

Figure 10 shows the advanced input filter and the symmetry it produces on its output signal. The upper

waveforms of Example 1 show an input signal with a pulse duration much longer than the filtering time t_FILIN; the

resulting output signal has approximately the same duration as the input signal. The lower waveforms of Example

2 show an input signal with a pulse duration slightly longer than the filtering time t_FILIN; the resulting output signal

has approximately the same duration as the input signal.

Short-Pulse and Noise Rejection

The advanced input filter that improves the input/output pulse symmetry of the signals processed by the HVIC

also helps the rejection of noise spikes and of short pulses on the input signals.

Input signals with a pulse duration less than the filtering time t_FILINwill be filtered out. In Figure 11 Example 1

shows an input signal in the low state with superimposed positive noise spikes of duration less than t_FILIN; the

advanced input filter filters out the noise spikes and the output signal remains in the low state. Example 2 shows

an input signal in the high state with superimposed negative noise spikes of duration less than t_FILIN; the

advanced input filter filters out the noise spikes and the output signal remains in the high state.

The measured characteristic of the advanced input filter is shown in Figure 12. On the left side the characteristic

for narrow ON pulses is shown (short positive pulse) while on the left side the characteristic for narrow OFF

pulses is shown (short negative pulse). The x-axis represents the input pulse duration PW_IN, while the y-axis the

resulting output pulse duration PW_OUT. For pulses with input pulse duration PW_INless than the filtering time t_FILIN

the resulting output pulse duration PW_OUTis zero because the filter rejects the input signal. For pulses with input

pulse duration PW_INgreater than the filtering time t_FILINthe resulting output pulse duration PW_OUTtracks the input

pulse durations well, the higher the duration the better the symmetry.

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 devices switch on and off quickly while carrying a large current. A typical 3-phase inverter

circuit is shown in Figure 14; where we define the power switches and diodes of the inverter.

If the high-side switch (e.g., the IGBT Q1 in Figures 15 and 16) 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 low-side switch of the same inverter leg. At the same instance, the voltage node V_S1, 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 17 and 18), and Q4

swings from the positive DC bus voltage to the negative DC bus voltage.

However, in a real inverter circuit, the V_Svoltage 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 V_Stransient‖.

The circuit shown in Figure 19 depicts one leg of the three phase inverter; Figures 20 and 21 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 L_Cand L_Efor each IGBT. When the high-side

switch is on, V_S1is 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 V_S1(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 V_S1and the DC- Bus is induced (i.e., the COM pin of the HVIC is at a higher potential

than the V_Spin).

Figure 21: V_Snegative

In a typical motor drive system, dV/dt is typically designed to be in the range of 3-5 V/ns. The negative V_S

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. An indication of the AUIRS2334‘s robustness can be seen in Figure 22, where there is represented

the AUIRS2334 Safe Operating Area at V_BS=15V based on repetitive negative V_Sspikes. A negative V_Stransient

voltage falling in the grey area (outside SOA) may lead to IC permanent damage; vice versa unwanted functional

anomalies or permanent damage to the IC do not appear if negative Vs transients fall inside SOA.

At V_BS=15V in case of -V_Stransients greater than -16.5 V for a period of time greater than 50 ns; the HVIC will

hold by design the high-side outputs in the off state for 4.5 μs.

Even though the AUIRS2334 has been shown able to handle these large negative VS transient conditions, it is

highly recommended that the circuit designer always limit the negative V_Stransients 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 (V_Band V_S) near the respective high voltage portions of the device. Please see the Case

Outline 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

23). 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.

Supply Capacitor: It is recommended to place a bypass capacitor between the VCC and COM pins. This

connection is shown in Figure 24. 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 source to low-side collector distance, and 2) minimize

the low-side emitter to negative bus rail stray inductance. However, where negative V_Sspikes remain excessive,

further steps may be taken to reduce the spike. This includes placing a resistor (5 Ω or less) between the V_Spin

and the switch node (see Figure 25), and in some cases using a clamping diode between COM and V_S(see

Figure 26). See DT04-4 at www.irf.com for more detailed information.

Parameter Temperature Trends

Figures 27-44 provide information on the experimental performance of the AUIRS2334 HVIC. The line plotted

in each figure is generated from actual experimental data. A small number of individual samples were tested

at three temperatures (-40 ºC, 25 ºC, and 125 ºC) in order to generate the experimental 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 temperature trend. The individual data points on the curve

were determined by calculating the averaged experimental value of the parameter (for a given temperature).
