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 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.

From these figures, we can see the definitions of several timing parameters (i.e. tON, tOFF, tR, and tF) associated with this device. 50% HIN LIN 50% HIN LIN tON tR tOFF 90% HO LO Figure 6 HO LO 90% 10% Switching timing diagram Datasheet www.infineon.com/soi tF 10% Figure 7 9 of 24 Input/output logic diagram V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side driver with integrated bootstrap diode 5.3 Matched propagation delays The 2ED2181 (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., t ON, 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 (tON) of the 2ED2181 (4) S06F (J) is matched to the propagation turn-on delay (tOFF). 50% 50% HIN LIN LO HO 10% MT MT 90% LO Figure 8 Delay matching waveform definition 5.4 Input logic compatibility HO 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 (VIH) of 2.1 V and typical low threshold (VIL) of 0.9 V, along with very little temperature variation as summarized in Figure 9, 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.

Figure 10 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 won’t 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. Upon power-up, should the VBS voltage fail to reach the VBSUV+ threshold, the IC won’t 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 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 11 and 12. Figure 11 2ED218x with integrated components Figure 12 Datasheet www.infineon.com/soi 11 of 24 Standard bootstrap gate driver V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side 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 CBS 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 13. 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 13 Half bridge bootstrap circuit in 2ED218x When the low side MOSFET turns on, it will force the potential of pin VS to GND. The existing difference between the voltage of the bootstrap capacitor VCBS and VCC results in a charging current IBS into the capacitor CBS. The current IBS is a pulse current and therefore the ESR of the capacitor CBS must 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 DBS blocks a reverse current, so that the charges on the capacitor cannot flow back to the capacitor CVCC. The bootstrap diode DBS also takes over the blocking voltage between pin VB and VCC. 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 CBS, 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 RBS according to Figure 13 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 CBS is 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 Datasheet www.infineon.com/soi 12 of 24 V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side driver with integrated bootstrap diode 𝐶𝐵𝑆 = 𝑄𝐺𝑇𝑂𝑇 ∆𝑉𝐵𝑆 VBS is 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 VBS ≤ (VCC – VF– VGSmin– VDSon) VGSmin > VBSUV- , VGSmin is the minimum gate source voltage we want to maintain and VBSUV- is the high-side supply undervoltage negative threshold. VCC is the IC voltage supply, VF is bootstrapdiode forward voltage and VDSon is drain-source voltage of low side MOSFET. Please note, that the value QGTOT may 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 VBS to decrease are: - MOSFET turn on required Gate charge (QG) - MOSFET gate-source leakage current (ILK_GS) - Floating section quiescent current (IQBS) - Floating section leakage current (ILK) - Bootstrap diode leakage current (ILK_DIODE) - Charge required by the internal level shifters (𝑄𝐿𝑆 ): typical 1nC - Bootstrap capacitor leakage current (ILK_CAP) - High side on time (THON) Considering the above, 𝑄𝐺𝑇𝑂𝑇 = 𝑄𝐺 + 𝑄𝐿𝑆 + (𝐼𝑄𝐵𝑆 + 𝐼𝐿𝐾𝐺𝑆 + 𝐼𝐿𝐾 + 𝐼𝐿𝐾𝐷𝐼𝑂𝐷𝐸 + 𝐼𝐿𝐾𝐶𝐴𝑃 ) ∗ 𝑇𝐻𝑂𝑁 ILK_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 CBS equation 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.

A typical 3-phase inverter circuit is shown in Figure 15, here 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 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 VS1, swings from the positive DC bus voltage to the negative DC bus voltage. DC+ BUS D1 Q1 Input Voltage VS1 Q2 D3 Q3 VS2 U D2 Q4 D5 Q5 VS3 V D4 Q6 W To Load D6 DC- BUS Figure 15 Three phase inverter Also when the V phase current flows from the inductive load back to the inverter (see Figures 16 C) and D)), 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” Datasheet www.infineon.com/soi 14 of 24 V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side driver with integrated bootstrap diode DC+ BUS Q1 ON Q1 OFF DC+ BUS DC+ BUS DC+ BUS D1 D3 Q3 OFF IU D3 Q3 OFF IV VS1 VS2 VS2 VS1 IV IU D2 Q2 OFF Q2 OFF A) DC- BUS Figure 16 D2 B) DC- BUS A) Q1 conducting D4 Q4 OFF DC- BUS B) D2 conducting Q4 ON C) D3 conducting D) DC- BUS C) D) Q4 conducting The circuit shown in Figure 17-A depicts one leg of the three phase inverter; Figures 17-B and 17-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 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).

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 2ED2181’s robustness can be seen in Figure 18, where the 2ED2181’s Safe Operating Area is shown at VBS=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.

The level shifter circuit is with respect to COM (refer to Block Diagram on page 4), the voltage from VB to 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 19. 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 VB – VS voltage is different, the minimum VS voltage changes accordingly. VS COM - 11 V Figure 19 Headroom for HV level shifter data transmission 5.12 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 Datasheet www.infineon.com/soi 16 of 24 V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side driver with integrated bootstrap diode 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 TJ can be calculated with 𝑇𝐽 = Pd ∙ 𝑅𝑡ℎ𝐽𝐴 + 𝑇𝐴_𝑚𝑎𝑥 , where TA_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)” The output section is the major contributor for the power dissipation of the gate driver IC. The external gate resistors also contribute to the power disspation of the gate driver IC. The bigger the external gate resistor, the smaller the power dissipation in the gate driver. The losses of the output section are calculated by means of the total gate charge of the power MOSFET or IGBT it is driving Qgtot, the supply voltage VCC, the switching frequency fP, and the ext. gate resistor Rgon and Rgoff. Different cases for turn-on and turn-off must be considered, because many designs use different resistors for turn-on and turn-off. This leads to a specific distribution of losses in respect to the external gate resistor R gxx, ext and the internal resistances (Ron_int and Roff_int) of the output section. 2 𝑅𝑜𝑛_𝑖𝑛𝑡 Turn on losses: 𝑃𝑑𝑜𝑛 = 2 × 𝑄𝑔𝑡𝑜𝑡 × 𝑉𝑐𝑐 × 𝑓𝑝 × 𝑅𝑜𝑛_𝑖𝑛𝑡+𝑅𝑔𝑜𝑛_𝑒𝑥𝑡 2 𝑅𝑜𝑓𝑓_𝑖𝑛𝑡 Turn off losses: 𝑃𝑑𝑜𝑓𝑓 = 2 × 𝑄𝑔𝑡𝑜𝑡 × 𝑉𝑐𝑐 × 𝑓𝑝 × 𝑅𝑜𝑓𝑓_𝑖𝑛𝑡+𝑅𝑔𝑜𝑓𝑓_𝑒𝑥𝑡 The above two losses are then added to the remaining static losses within the gate driver IC and we arrive at the below figure which estimates the gate driver IC temperature rise when switching a given MOSFET or IGBT at different switching frequencies. 140 120 100 80 60 40 20 10.00 100.00 Switching Frequency (kHz) IPW60R037P7 2ED218xS06J family gate drivers temperature rise Driver IC Junction Temperature (°C) Driver IC Junction Temperature (°C) 2ED218xS06F family gate drivers temperature rise IPP60R180P7 140 120 100 80 60 40 20 10.00 100.00 Switching Frequency (kHz) IPW60R037P7 IPP60R360P7 IPP60R180P7 IPP60R360P7 *Assumptions for above curves: Ta = 25 °C, VBUS = 400 V, VCC = 12 V, Rgon = 10 Ω, Rgoff = 5Ω Figure 20 Estimated temperature rise in the 2ED218x family gate drivers for different switching frequencies when switching CoolMOSTM SJ MOSFETs Datasheet www.infineon.com/soi 17 of 24 V 2.31 2021-10-11 2ED2181 (4) S06F (J) 650 V high-side and low-side driver with integrated bootstrap diode 5.13 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. 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 21). 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 21 Avoid antenna loops Supply Capacitor: It is recommended to place a bypass capacitor (CIN) between the VCC and 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 22 - A), and in some cases using a clamping diode between COM and VS (see Figure 22- B). See DT04-4 at www.infineon.com for more detailed explanations.
