2ED2182 (4) S06F (J)

650 V half-bridge gate driver with integrated bootstrap diode

Description

The 2ED2182(4)S06F(J) is a half-bridge high voltage, high speed power MOSFET and IGBT driver with

independent high and low side referenced output channels. Based on Infineon’s SOI-technology there is an

excellent ruggedness and noise immunity with capability to maintain operational logic at negative voltages of

up to - 11 V_DCon VS pin (V_CC= 15 V) on transient voltages. There are not any parasitic thyristor structures present

in the device, hence no parasitic latch up may occur at all temperature and voltage conditions. The logic input is

compatible with standard CMOS or LSTTL output, down to 3.3 V logic. The output drivers feature a high pulse

current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive

an N-channel power MOSFET, SiC MOSFET or IGBT in the high side configuration, which operate up to 650 V.

Application information and additional details

5.1

IGBT / MOSFET gate drive

The 2ED2182 (4) S06F (J) HVIC is designed to drive MOSFET or IGBT power devices. Figures 4 and 5 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 I_O. The voltage that drives the gate of the external power switch

is defined as V_HOfor the high-side power switch and V_LOfor the low-side power switch; this parameter is

sometimes generically called V_OUTand in this case does not differentiate between the high-side or low-side output

voltage.

5.2

Switching and timing relationships

The relationships between the input and output signals of the 2ED2182 (4) S06F (J) are illustrated below in

Figure 6 and Figure 7. From these figures, we can see the definitions of several timing parameters (i.e. t_ON, t_OFF

t_R, and t_F) associated with this device.

5.3

Deadtime and matched propagation delays

This 2ED2182 (4) S06F (J) features integrated deadtime protection circuitry. The deadtime is fixed for

2ED2182S06F; is programmable for 2ED2182S06J, it provides 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 8 illustrates the deadtime

period and the relationship between the output gate signals.

The deadtime circuitry of 2ED2182 (4) S06F (J) is matched with respect to the high- and low-side outputs. Figure

9 defines the two deadtime parameters (i.e., DTLO-HO and DTHO-LO); the deadtime matching parameter (MDT)

associated with the 2ED2182S06F (J) specifies the maximum difference between DTLO-HO and DTHO-LO.

Delay Matching Waveform Definitions

The 2ED2182 (4) S06F (J) 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). The propagation turn-on delay (t_ON) of the 2ED2182 (4) S06F (J) is matched to the

propagation turn-on delay (t_OFF).

The 14-pin variant (2ED21824S06J) provides greater design flexibility with a programmable dead-time feature

using an external resistor (RDT) connected between the DT pin and VSS pin as shown in figure 10.

2ED2182 (4) S06F (J)

650 V half-bridge gate driver with integrated bootstrap diode

Figure 11 shows the linear relationship between the resistor (RDT) and dead time. Based on the end application,

designers can choose to add the external resistor to increase the dead time. In case the DT pin is left open, the

gate driver enters protection mode switching off the output stages. Hence this pin has to be connected to VSS

pin with a 0 ohm to 200 k resistor based on application requirements. A 0 ohm (or shorted) provides a minimum

deadtime of 400 ns and 200 k ohm provides a maximum deadtime of 5 us.

Input logic compatibility

The input pins of are based on a TTL and CMOS compatible input-threshold logic that is independent of the Vcc

supply voltage. With typical high threshold (V_IH) of 2.1 V and typical low threshold (V_IL) of 0.9 V, along with very

little temperature variation as summarized in Figure 12, the input pins are conveniently driven with logic level

PWM control signals derived from 3.3 V and 5 V digital power-controller devices. Wider hysteresis (typically 0.9

V) offers enhanced noise immunity compared to traditional TTL logic implementations, where the hysteresis is

typically less than 0.5 V. 2ED218x family also features tight control of the input pin threshold voltage levels which

eases system design considerations and ensures stable operation across temperature. The 2ED218x features

floating input protection wherein if any of the input pin is left floating, the output of the corresponding stage is

held in the low state. This is achieved using pull-down resistors on all the input pins (HIN, LIN) as shown in the

block diagram. The 2ED218x family has input pins that are capable of sustaining voltages higher than the bias

voltage applied on the Vcc pin of the device.

Undervoltage lockout

This IC provides undervoltage lockout protection on both the V_CC(logic and low-side circuitry) power supply and

the V_BS(high-side circuitry) power supply. Figure 13 is used to illustrate this concept; V_CC(or V_BS) is plotted over

time and as the waveform crosses the UVLO threshold (V_CCUV+/-or V_BSUV+/-)the undervoltage protection is enabled

or disabled.

Upon power-up, should the V_CCvoltage fail to reach the V_CCUV+threshold, the IC won’t turn-on. Additionally, if the

V_CCvoltage decreases below the V_CCUV-threshold during operation, the undervoltage lockout circuitry will

recognize a fault condition and shutdown the high and low-side gate drive outputs.

Upon power-up, should the V_BSvoltage fail to reach the V_BSUV+threshold, the IC won’t turn-on. Additionally, if the

V_BSvoltage decreases below the V_BSUV-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.

Bootstrap diode

An ultra-fast bootstrap diode is monolithically integrated for establishing the high side supply. The differential

resistor of the diode helps to avoid extremely high inrush currents when initially charging the bootstrap

capacitor. The integrated diode with its resistrance helps save cost and improve reliability by reducing external

components as shown below figures 14 and 15.

650 V half-bridge gate driver with integrated bootstrap diode

The low ohmic current limiting resistor provides essential advantages over other competitor devices with high

ohmic bootstrap structures. A low ohmic resistor such as in the 2ED218x family allows faster recharching of the

bootstrap capacitor during periods of small duty cycles on the low side transistor. The bootstrap diode is usable

for all kind power electronic converters. The bootstrap diode is a real pn-diode and is temperature robust. It can

be used at high temperatures with a low duty cycle of the low side transistor.

The bootstrap diode of the 2ED218x family works with all control algorithms of modern power electronics, such

as trapezoidal or sinusoidal motor drives control.

5.7

Calculating the bootstrap capacitance C_BS

Bootstrapping is a common method of pumping charges from a low potential to a higher one. With this technique

a supply voltage for the floating high side sections of the gate drive can be easily established according to Figure

16. 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.

Figure 16

Half bridge bootstrap circuit in 2ED218x

When the low side MOSFET turns on, it will force the potential of pin V_Sto GND. The existing difference between

the voltage of the bootstrap capacitor V_CBSand V_CCresults in a charging current I_BSinto the capacitor C_BS. The

current I_BSis a pulse current and therefore the ESR of the capacitor C_BSmust be very small in order to avoid losses

in the capacitor that result in lower lifetime of the capacitor. This pin is on high potential again after low side is

turned off and high side is conducting current. But now the bootstrap diode D_BSblocks a reverse current, so that

the charges on the capacitor cannot flow back to the capacitor C_VCC. The bootstrap diode D_BSalso takes over the

blocking voltage between pin V_Band V_CC. The voltage of the bootstrap capacitor can now supply the high side

gate drive sections. It is a general design rule for the location of bootstrap capacitors C_BS, that they must be placed

as close as possible to the IC. Otherwise, parasitic resistors and inductances may lead to voltage spikes, which

may trigger the undervoltage lockout threshold of the individual high side driver section.

The current limiting resistor R_BSaccording to Figure 16 reduces the peak of the pulse current during the low side

MOSFET turn-on. The pulse current will occur at each turn-on of the low side MOSFET, so that with increasing

switching frequency the capacitor C_BSis charged more frequently. Therefore a smaller capacitor is suitable at

higher switching frequencies. The bootstrap capacitor is mainly discharged by two effects: The high side

quiescent current and the gate charge of the high side MOSFET to be turned on.

The minimum size of the bootstrap capacitor is given by

∆V_BSis the maximum allowable voltage drop at the bootstrap capacitor within a switching period, typically 1 V.

It is recommended to keep the voltage drop below the undervoltage lockout (UVLO) of the high side and limit

∆V_BS≤ (V_CC– V_F– V_GSmin– V_DSon

)

V_GSmin> V_BSUV-, V_GSminis the minimum gate source voltage we want to maintain and V_BSUV-is the high-side supply

undervoltage negative threshold.

V_CCis the IC voltage supply, V_Fis bootstrapdiode forward voltage and V_DSonis drain-source voltage of low side

MOSFET.

Please note, that the value Q_GTOTmay vary to a maximum value based on different factors as explained below and

the capacitor shows voltage dependent derating behavior of its capacitance.

The influencing factors contributing V_BSto decrease are:

- MOSFET turn on required Gate charge (Q_G)

- MOSFET gate-source leakage current (I_{LK_GS}

)

- Floating section quiescent current (I_QBS

- Floating section leakage current (I_LK)

- Bootstrap diode leakage current (I_{LK_DIODE}

- Charge required by the internal level shifters (ꢃ_ꢈꢂ): typical 1nC

- Bootstrap capacitor leakage current (I_{LK_CAP}

)

- High side on time (T_HON

)

I_{LK_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 capacitor

and low ESR ceramic capacitor may result in an efficient solution).

The above C_BSequation is valid for pulse by pulse considerations. It is easy to see, that higher capacitance values

are needed, when operating continuously at small duty cycles of low side. The recommended bootstrap

capacitance is therefore in the range up to 4.7 μF for most switching frequencies. The performance of the

integrated bootstrap diode supports the requirement for small bootstrap capacitances.

5.8

Tolerant to negative tranisents on input pins

Typically the driver's ground pin is connected close to the source pin of the MOSFET or IGBT. The microcontroller

which sends the HIN and LIN PWM signals refers to the same ground and in most cases there will be an offset

voltage between the microcontroller ground pin and driver ground because of ground bounce. The 2ED218x

family can handle negative voltage spikes up to 5 V. The recommended operating level is at negative 4 V with

absolute maximum of negative 5 V. Standard half bridge or high-side/low-side drivers only allow negative voltage

levels down to -0.3 V. The 2ED218x family has much better noise immunity capability on the input pins.

5.9

Negative voltage transient tolerance of VS pin

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 18, here we define the power switches and diodes of the inverter.

If the high-side switch (e.g., the IGBT Q1 in Figures 19 and 20) switches from on to 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.

Figure 18 Three phase inverter

Also when the V phase current flows from the inductive load back to the inverter (see Figures 19 C) and D)), and

Q4 IGBT switches on, the current commutation occurs from D3 to Q4. At the same instance, the voltage node, V_S2,

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 V_Stransient”

The circuit shown in Figure 20-A depicts one leg of the three phase inverter; Figures 20-B and 20-C 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).

NTSOA – Negative Transient Safe Operating Area

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.

Infineon’s HVICs have been designed for the robustness required in many of today’s demanding applications. An

indication of the 2ED2182’s robustness can be seen in Figure 21, where the 2ED2182’s Safe Operating Area is

shown at V_BS=15 V based on repetitive negative VS spikes. A negative VS transient voltage falling in the grey area

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

Recommended safe operating area

Even though the 2ED2182S06F(J) 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.

Higher headroom for input to output signal transmission with logic

operation upto -11 V

If there is not enough voltage for the level shifter to transmit a valid signal to the high side.High side driver doesn’t

turn on. The level shifter circuit is with respect to COM (refer to Block Diagram on page 4), the voltage from V_Bto

COM is the supply voltage of level shifter. Under the condition of VS is negative voltage with respect to COM, the

voltage of VS - COM is decreased, as shown in Figure 22. There is a minimum operational supply voltage of level

shifter, if the supply voltage of level shifter is too low, the level shifter cannot pass through HIN signal to HO. If V_B

– V_Svoltage is different, the minimum VS voltage changes accordingly.

Maximum switching frequency

The 2ED218x family is capable of switching at higher frequencies as compared to standard half-bridge or high

side / low side gate drivers. They are available in two packages, the PG-DSO-8 and the PG-DSO-14. It is essential

to ensure that the component is not thermally overloaded when operating at higher frequencies. This can be

checked by means of the thermal resistance junction to ambient and the calculation or measurement of the

dissipated power. The thermal resistance is given in the datasheet (section 4) and refers to a specific layout.

Changes of this layout may lead to an increased thermal resistance, which will reduce the total dissipated power

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

24). 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 (C_IN) between the V_CCand COM pins. A ceramic

1μF 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 25), and in some cases using a clamping diode between COM and V_S

(see Figure 26). See DT04-4 at www.infineon.com for more detailed explanations.
