Overview and Setup Si8284v2-EVB can be used to demonstrate the isolated gate drive capabilities of the installed Si8284DD-IS. The Si8284 includes a DCDC converter used to supply isolated power to the gate driver. The following scenarios are specifically supported: • Demonstration of gate driver with no load, observing VGS and VDS • • • • Demonstration of gate driver with pre-installed capacitive load, observing load current Demonstration of gate driver with SiC / MOSFET / IGBT gate load (switch devices not included in Kit) Demonstration of gate driver / Switch desaturation functionality, with Fault Indication and Fault clearing by Reset Evaluation of gate driver / Switch performance with double pulse test and inductive load 1.1 Hardware Figure 1.1.

Low Voltage Side Supply power to the input side of Si8284 by applying +9 to +24 VDC (at least 0.5 A) to VDDP at terminal block J1 pin 1 and applying its return at pin 2, labeled GNDA. Green LED D6 above terminal block J1 illuminates to show power applied. The jumper at header JP6 (installed by default) may be removed to disable LED D6. For interfacing to the low voltage side of Si8284, VDDA supply must be between 3.0 and 5.5 VDC. Either a separate supply can be connected to VDDA terminal on J1 pin 3 (with return on pin 2, JP4 must be removed) or 5 VDC can be derived from VDDP through the on-board regulator circuit and directed to VDDA through a jumper at header JP4 (installed by default). Green LED D5 below terminal block J1 illuminates to show VDDA power is applied. The jumper at header JP5 (installed by default) may be removed to disable LED D5. SMA connector J16 (found on the back side of the board) provides access to the IN+ input through a 50 Ω resistor. The reference pin of J16 and the IN- input of the Si8284 are grounded to the low-voltage reference GNDA. The pins IN+ and IN- may also be monitored at test points TP14 and TP15, respectively. Driver functionality can be exercised without a controller by applying a GNDA-referenced PWM signal from a function generator to J16. Maximum allowable input voltage is VDDA. The RSTb pin (shown as /RST in the schematic) is controlled by momentary switch S1. The pin may be monitored or externally controlled at test point TP11. RSTb is passively pulled up by a 10 kΩ resistor, R8. The active high SH input pin is normally held low by a jumper installed at header JP11 (installed by default) which also serves as a sink for the frequency control (FC) current, but the DC-DC converter may be disabled by removing the jumper and allowing the input to be pulled high by 1k resistor, R54. The pin may be monitored at test point TP10. The Ready pin indicates to the controller that power is available on both sides of the isolation, i.e., at VDDA and VDDB. RDY goes high when both the primary side and secondary side UVLO circuits are disengaged. If either VDDA or VDDB drops below its UVLO threshold, the ready pin will return low. RDY is a push-pull output pin and can be floated if not used. An active RDY is visually indicated by illumination of the green LED D17. FLTb (/FLT in the schematic) is an open-drain type output. A pull-up resistor R9 takes the pin high. When the desaturation condition is detected, the Si828x indicates the fault by bringing the FLTb pin low. FLTb stays low until the controller or the user brings the RSTb pin low. An active FLTb is visually indicated by illumination of the red LED D18. 4 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 4 UG482: Si8284v2-EVB User's Guide • Overview and Setup The FLTb and RDY outputs of the Si8284 may be monitored at test points TP12 and TP13, respectively. The open drain FLTb output allows multiple gate drivers’ FLTb outputs to share the same microcontroller input. The RDY output has a pull-down resistor to GNDA. 1.1.2 DC-DC Operation The isolated DC-DC converter is configured to generate (with respect to VMID) +15 V for VDDB and -3.5 V for VSSB. Green LEDs D8 and D7 illuminate when VDDB and VSSB are powered respectively. LED D8 may be disabled by removing the jumper at header JP7 (installed by default), and LED D7 may be disabled by removing the jumper at header JP8 (installed by default). DC-DC operation can be disabled by removing the jumper at header JP11 (installed by default). 1.1.3 Si8284 Isolated Gate Drive Connections There is a provision for a 3- or 4-pin SiCFET, a MOSFET, or an IGBT in a TO-247 package (not supplied) at Q1. The same part number should be used at Q8, which is connected in the off mode as a rectifying diode between Q1 drain and the DCRAIL connector. From top to bottom in the layout, the through holes for the transistor leads are Gate, Drain/SiC Drain, Source/SiC Source, SiC Source Kelvin Sense, and SiC Gate. The top three holes accommodate a 3-pin (including SIC) device in TO-247 (G, D, S). Alternately, the bottom four holes accommodate a 4-pin SiC device in TO-247 (D, S, SK, G). The fourth hole (SK) is offset to accommodate the hole size. The switching FET (load) transistor is biased by applying voltage across DCRAIL (J17) and DCRAIL_GND (J19). This voltage should not exceed the rated VDS of the transistor or 1000 V (the output capacitor voltage rating), whichever is lower. Supply voltage constraints are summarized in the table below. Note: Si8284 can drive the gate of either high-side or low-side MOSFET or IGBT in a bridge configuration. VMID is the same net as the load when driving the gate of a high side MOSFET or IGBT. For a gate drive for a low side MOSFET or IGBT, VMID is the return for the load. Table 1.1. Supply Voltage Constraints 3.0 V ≤VDDA – GNDA ≤ 5.5 V 9 V ≤ VDDP ≤24 V VSSB ≤VMID < VDDB UVLO +1 < VDDB -VSSB < 30 V DCRAIL < MOSFET VDS rating or 1kV, whichever is lower |GNDA – VSSB| < 5 kV Note: 1.

This requires population of R48 – R51 and R62, populated by default. The gate resistors (R38, R42) are 3 ohms installed. These may be reduced to 0 ohms to get maximum gate drive current from the current boost circuit. Option – Direct Drive from Si8284: To revert to direct, non-boosted gate drive from the Si8284, depopulate R48 – R51 and R62, and populate R10 – R12 and R52 (seen on Si8284 HV and SiC circuit page). Figure 1.3. Current Boost Circuit 1.2.2 Positive Voltage Gate Drive Only The standard configuration has the gate driver apply positive voltage, VDDB-VMID, to the gate during the high drive portion of the PWM cycle and negative voltage, VMID-VSSB, during the low drive portion of the PWM cycle. Alternatively, if only positive drive voltage is needed, remove R13 and install a 0 Ω size 0805 resistor at R19 (R13 and R19 are found in Figure 4.1 Si8284v2-EVB Low-Voltage Circuit Schematic on page 21). This will short VSSB to VMID. 1.2.3 Alternate VDDB Voltage The EVB comes with a jumper populated to JP12, pins 1 and 2. This causes VDDB to be +15 V and VSSB to be -3.5 V. To have VDDB equal to +17 V and VSSB equal to -5 V, set the jumper at JP12 to pins 2 and 3. 6 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 6 UG482: Si8284v2-EVB User's Guide • Demonstrating Driver Functionality 2. Demonstrating Driver Functionality Even with no load (neither capacitor nor SiC-FET switching transistor) present, the basic functionality of the Si8284 can be demonstrated. To run this demonstration, disable the on-board capacitive load (C43, 220 nF) by removing resistor 57. Save the resistor for later use. 1. Apply 9V- 24 V to VDDP at J1, pin 1 (return at pin 2) to power both sides of the Si8284. With jumpers installed at headers JP5–JP8, D5–D8 will illuminate indicating supplies are biased. 2. Apply a jumper at JP4. This allows VDDP to be regulated down to produce VDDA. 3. Leave DCRAIL unpowered. Install a jumper at JP9 pins 2 and 3. This jumper disables desaturation detection and allows for operation of the Si8284. Since both sides of the Si8284 have been powered on, RDY will output 5 V, which can be observed at green LED D17 or TP13. 4. Apply a 5 V dc signal to SMA J16 or TP14. Output VH will go High, output VL will go Hi-Z, and +15 V can be observed at SMA J13, or VGS. 5. Apply a 0 V dc signal to SMA J16 or TP14. Output VH will go Hi-Z, output VL will go Low, and -3.5 V can be observed at SMA J13, or VGS. 6. Gate drive voltage signal may be observed at VGS (J13), an SMA-type coaxial connector. 7. A PWM signal may be applied at J16 and observed at J13 as the gate drive signal. 7 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 7 UG482: Si8284v2-EVB User's Guide • Demonstrating Driver Functionality 2.1 Driving a Capacitive Load If the driver is exercised dynamically (with a PWM waveform at J16) with R57 installed to use C43 as a FET driver load, its drive current may be observed at IDRV (J12), an SMA-type coaxial connector. The load current develops a voltage across R46, a 0.05 Ω, 2 W resistor. R57 should be removed if the circuit is to be operated with a MOSFET installed at Q1. Note that a jumper is installed at JP9 pins 2 and 3 to disable DESAT and enable this test. 1. Populate R57 (populated by default). 2. Set up the low voltage side as described in 1.1 Hardware. 3. Apply a pulse signal to the input SMA connector J16, with value between 0 V and VDDA. A 20 us pulse width and 60 us pulse period is a useful starting point. 4. Observe the voltage output signal at J13, VGS. Display this signal on an oscilloscope. The signal will range from -3.5 V to +15 V. 5. Attach a coaxial cable to the SMA connector J12, IDRV. Display this signal on an oscilloscope. The signal is developed across a 0.05 Ω resistor, so the current can be seen at 10 A/div if the channel voltage setting is 500 mV/div Figure 2.1. Si8284v2-EVB Connection for Driver and Capacitive Load Testing This test can be run either with or without the current boost circuit. The board comes configured with the current boost circuit connected. If R38 and R42 (gate resistors) are both 0 Ω, then the following response can be obtained, where the yellow trace is the gate waveform and the magenta trace is the gate current. 8 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 8 UG482: Si8284v2-EVB User's Guide • Demonstrating Driver Functionality Figure 2.2.

This board may contain high voltages. Do not touch the board once the high voltage section has been energized. Figure 2.8. Si8284v2-EVB Connection for Double Pulse Test 1. The double pulse test will require installation of Q8, a device identical to Q1, to provide an inductor discharge path when the gate drive is low. Q8 is set up as an off device, and its body diode conducts reverse current from the inductor when gate drive is off. 2. Remove jumper from JP9 to enable DESAT detection. Detection may be sped up by placing a jumper at JP9, pins 1 and 2. 3. R73 is a 5 mΩ resistor for monitoring source current. The resistor is in parallel with J15. If desired, remove resistor R73 to allow the current viewing port to be installed. Install a T&M Research Products SDN Series 2 Watt current viewing port at J15 if this has not already been done. T&M current sensor should be installed with the center leg connected to J15-SOURCE so that all scope probes reference to the same GND. To view the current waveform from the reversed T&M current sensor connection, the scope input should be set in reversed polarity so that the current signal appears in its proper polarity (see figure Figure 2.10 Typical Signal Traces During Double Pulse Test on page 16). As shown in Figure 2.8 Si8284v2-EVB Connection for Double Pulse Test on page 14, a current monitoring loop may be installed in lieu of the current viewing port, and a current probe clamp may be used to view the source node current. 4. Set up the low voltage side as described in 1.1 Hardware, but don’t energize the low-voltage supplies. 5. Install an inductor between terminal blocks J17 (DCRAIL) and J18 (DRAIN). An air core inductor of 50uH value and 150A rating is suggested. This can tolerate the DCRAIL voltage for 10 uS. 6. Preset a DCRAIL source to a value less than the lower of 1kVrms and the FET rating, and de-energize. 7. Attach the DCRAIL source to terminal block J17 (DCRAIL) with its return at J19 (DCRAIL_GND). 8. Prepare to apply a 5 V double pulse at J9 – J10 (IN+ - IN-). 9. Perform this step before energizing the board.

Features See AN1288: Si828x External Enhancement Circuits for additional information. 3.1 DESAT Speed up/Disable The DESAT function blanking time may be reduced, whether or not you are using the driver BOM enhancements for SiC devices. Placing a jumper at header JP9 pins 1 and 2 will add current from the VH pin to the CBL charging current when the DESAT blanking function is active, causing the CBL C16 to be charged more rapidly and the output to be pulled low sooner than otherwise. Placing the jumper at header JP9 pins 2 and 3 will disable the DESAT function. 3.2 DESAT Threshold The DESAT threshold may be altered by removing R77 and replacing it with Zener diode D21. The Zener value will be subtracted from the nominal DESAT threshold of 7.0 V. Another approach is to change the value of R4 according to the description in AN1288: Si828x External Enhancement Circuits. 3.3 Soft Shutdown Duration Soft shutdown duration may be modified by changing the value of R43 according to the description in AN1288: Si828x External Enhancement Circuits. Decreasing the value will reduce the duration. 17 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 17 UG482: Si8284v2-EVB User's Guide • Features 3.4 Source Current Viewing Port There is a 5 mOhm resistor (R73) in parallel with a BNC connector (J15) for easy monitoring of source current. The resistor is in parallel with J15. There is also a provision for a current view port at J15. This is for the insertion of a device such as T&M Research Products SDN Series 2-Watt Unit, or a wire loop for use with a current clamp probe. If this will not be used, install the resistor R73. If using the T&M Research current sensor, the sensor should be connected with the center pin connected to J15-SOURCE. The scope polarity should be set to inverted polarity with 50 Ohms input impedance. Adjust the scope's current setting to match the T&M sensor V/A rating. Figure 3.1.

Si8284v2-EVB with Loop Current Sense 3.5 FET Gate Observation J13 is an SMA-type coaxial connector for direct observation of the FET gate drive voltage. Its reference voltage is VMID/GNDB. The best approach to monitor this point is by using an SMA-to-BNC converter, then a BNC to scope probe adapter. Use a compensated probe and the high impedance input setting of the oscilloscope. 3.6 FET Drain Observation Drain-source voltage of Q1 may be observed at BNC connector J20 by connecting a coaxial cable between J20 and a differential probe. 3.7 Gate Drive Test Load A Gate Drive Test Load comprises C43 (220 nF) and R46 (0.05 Ω, 2 W). The current in this test load may be observed at J12, an SMA-type coaxial connector labeled IDRV. Its reference voltage is VMID. This is normally used with no FET installed at Q1. When installing Q1, remove C43 so there is no unnecessary load on the gate drive. 3.8 Switch Device Q1/Q8 Heatsink There is a footprint provision for attaching a heat sink to Q1/Q8. The suggested parts are Ohmite CR101-25-AE or CR101-50-AE. Also use BERGQUIST SIL-PAD 900S Thermal Material Electrical Insulator between the heat sink and the MOSFET, as the heat sink is grounded to DCRAIL_GND while the drain of the MOSFET may be at hazardous high voltages. 3.9 Secondary Side Supply Voltage Modification Using JP12 JP12 provides a means to select VDDB and VSSB for use with either SiC devices or IGBT devices. The default jumper position is at pins 1 and 2 for VDDB = 15 V and VSSB = -3.5 V. Moving the jumper to pins 2 and 3 changes VDDB to 17 V and VSSB to -4.5 V for use with IGBT devices. 19 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.1 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 19 UG482: Si8284v2-EVB User's Guide • Features 3.10 Quick Reference Table Table 3.1.
