2ED21091S06F

650 V half bridge gate driver with integrated bootstrap diode

Description

The 2ED21091S06F is a 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 on 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 2ED21091S06F HVIC is designed to drive MOSFET or IGBT power devices. Figure 4 and Figure 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.

5.3

Deadtime

This family of HVICs features integrated deadtime protection circuitry. The deadtime is programmable for

2ED21091S06F, it is 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 inserted whenever the external deadtime is shorter than interal deadtime; external deadtimes

larger than internal deadtime 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 2ED21091S06F is matched with respect to the high- and low-side outputs. Figure 8

defines the two deadtime parameters (i.e., DT_LO-HOand DT_HO-LO); the deadtime matching parameter (MDT)

associated with the 2ED21091S06F specifies the maximum difference between DT_LO-HOand DT_HO-LO

.

Figure 8

Deadtime matching waveform definition

5.4

Matched propagation delays

The 2ED21091S06F 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 2ED21091S06F is matched to the propagation turn-

off delay (t_OFF).

Shutdown input

2ED21091S06F provides a shutdown functionality that allows to disable the output. When /SD in pulled down

(the disable voltage is lower than V_SD,TH) the output is disable. Once the external pull down is released, the

output is active. The relationships between the input, output and enable signals of the 2ED21091S06F are

illustrated below in Figure 7 / 10. From these figures, we can see the definition of the parameter (i.e. t_SD)

associated with this device.

Note: If the DT/SD is floating, the output is aslo disable.

Figure 10 Shutdown waveform definitions

5.6

Input logic compatibility

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

supply voltage. Figure 11 illustrates an input signal to the 2ED21091S06F, its input threshold values, and the

logic state of the IC as a result of the input signal. The typical high threshold (V_IH) of 2.1 V and typical low

threshold (V_IL) of 0.9 V. 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.

2ED21091S06F also features tight control of the input pin threshold voltage levels which eases system design

considerations and ensures stable operation across temperature. The 2ED21091S06F 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 12 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 Figure 13 and Figure 14.

2ED21091S06F

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 2ED210x family allows faster recharging of the

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

pn-diode which works with all control algorithms of modern power electronics, such as trapezoidal or

sinusoidal motor drives control.

5.9

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 15. 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 15 Half bridge bootstrap circuit in 2ED210x

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.

However, all parts of the 2ED210x family, which have the UVLO also contain a filter at each supply section in

order to actively avoid such undesired UVLO triggers.

The current limiting resistor R_BSaccording to Figure 15 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.

∆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.

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 IN PWM signal 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

2ED210x 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 gate drivers only allow

negative voltage levels down to -0.3 V. The 2ED210x family has much better noise immunity capability on the

input pins.

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

If the high-side switch (e.g., the IGBT Q1 in Figure 18) 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.

Also when the V phase current flows from the inductive load back to the inverter (see Figure 18 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 19-A depicts one leg of the three phase inverter; Figure 19-B and 19-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 2ED21091S06F’s robustness can be seen in Figure 20, where the 2ED21091S06F’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 (outside SOA) may lead to IC permanent damage; viceversa unwanted functional

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

Even though the 2ED21091S06F 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 21. 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 IN

signal to HO. The specification of VS is –11 V as the internal structure allows a voltage difference of 15 V

between Vcc and COM pins. If V_B– V_Svoltage is different, the minimum VS voltage changes accordingly.

Maximum switching frequency

The 2ED21091S06F is capable of switching at higher frequencies as compared to standard half-bridge or high

side / low side gate drivers. 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 of the driver IC. One should therefore do temperature

measurements in order to avoid thermal overload under application relevant conditions of ambient

temperature and housing.

The maximum chip temperature T_Jcan be calculated with

ꢖ = Pd ∙ ꢚꢛℎ_ꢙꢜ+ ꢖ

, where T_{A_max}is the maximum ambient temperature.

The dissipated power Pd by the driver IC is a combination of several sources. These are explained in detail in

the application note “Advantages of Infineon’s Silicon on Insulator (SOI) technology based High Voltage Gate

Driver ICs (HVICs)”

Here is the example of the figures which estimates the gate driver IC junction temperature when switching a

given MOSFET at different switching frequencies.

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 coulping, 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 coulping 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 23 Avoid antenna loops

Supply Capacitor: It is recommended to place a bypass capacitor (C_IN) between the V_CCand COM pins. A

ceramic 1μFceramic capacitor issuitable for most applications. Thiscomponent should be placed asclose 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 24 - A), and in some cases using a clamping diode between

COM and V_S(see Figure 24 - B). See DT04-4 at www.infineon.com for more detailed explanations.
