The Heyday Integrated Circuits HEY-HBDS-G-12C1-A board is a daughter board containing two HEY1011-L12A GaN FET drivers and two GaN FETs configured in a half bridge configuration that plugs into the GaN Systems universal motherboard. The latest data sheet for the HEY1011 can be found in our [resources ](https://bgouverneur.ovh/resources) *![HEY-HBDS-12C1-A fig2](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig2.jpg)* *Figure 2: HEY-HBDS-G-12C1-A Evaluation Board* For full details of how to use the GaN Systems EVK see their users guide available at: [https://gansystems.com/gan-transistors/gs66508b-2/#board](https://gansystems.com/gan-transistors/gs66508b-2/#board)   |   ![hazard](https://www.heyday-ic.com/hubfs/resources/hazard.png)   | DANGER **DO NOT TOUCH THE BOARD WHEN IT IS ENERGIZED AND ALLOW ALL COMPONENTS TO DISCHARGE COMPLETELY PRIOR HANDLING THE BOARD.** **HIGH VOLTAGE CAN BE EXPOSED ON THE BOARD WHEN IT IS CONNECTED TO POWER SOURCE. EVEN BRIEF CONTACT DURING OPERATION MAY RESULT IN SEVERE INJURY OR DEATH.** Please ensure that appropriate safety procedures are followed. This evaluation kit is designed for **engineering evaluation in a controlled lab environment and should be handled by qualified personnel ONLY**. Never leave the board operating unattended. | | --- | --- | | ![warning](https://www.heyday-ic.com/hubfs/resources/warning.png)   | **WARNING** Some components can be hot during and after operation. **There is NO built-in electrical or thermal protection on this evaluation kit**. The operating voltage, current, and component temperature should be monitored closely during operation to prevent device damage. | | ![ESD](https://www.heyday-ic.com/hubfs/resources/ESD.png)   | **CAUTION** This product contains parts that are susceptible to damage by electrostatic discharge (ESD). Always follow ESD prevention procedures when handling the product.  |   ## Quick Start Guide   ![HEY-HBDS-12C1-A fig3](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig3.png)   *Figure 3: HEY-HBDS-G-12C1-A Quick Start* The HEY1011-L12A gate driver does not require a secondary side power supply nor bootstrap components. Gate drive power is transferred across the isolation barrier using our patented Power-thru technology.   The HEY1011-L12A requires a single primary side VDRV voltage of between 7.5V and 10V This VDRV supply should be applied to connector J1 pin 3   The input gate signals can be supplied also through J1 or through connector J2 as described in the GaN Systems users guide. 1. Apply VDRV = 8.0V 2. Apply input gate signals, with adequate dead time, to the IN\_L and IN\_H inputs. 3. Convenient test points a located on the test board as shown above. A suitable differential oscilloscope should be used to monitor the high side gate signal from VGH to VSW. ## PCB Layout ### HEY-HBDS-G-12C1-A   ![HEY-HBDS-12C1-A fig4](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig4.png) *Figure 4: HEY-HBDS-G-12C1-A component placement*   ![HEY-HBDS-12C1-A fig5](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig5.png)     *Figure 5: HEY-HBDS-G-12C1-A Silkscreen*    ![HEY-HBDS-12C1-A fig6](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig6.png)   *Figure 6: HEY-HBDS-G-12C1-A Topside copper*   *![HEY-HBDS-12C1-A fig7](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig7.png)* *Figure 7: HEY-HBDS-G-12C1-A Layer 2 copper*   ![HEY-HBDS-12C1-A fig8](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig8.png) *Figure 8: HEY-HBDS-G-12C1-A Layer 3 copper*   ![HEY-HBDS-12C1-A fig9](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig9.png) *Figure 9: HEY-HBDS-G-12C1-A Bottom side copper*   ## Schematic   ![HEY-HBDS-12C1-A fig10](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig10.png) *Figure 10: HEY-HBDS-G-12D1-C Schematic*     ## Bill of materials   | **Item** | **Ref Name** | **Description** | **Manufacturer** | **Part Number** | | --- | --- | --- | --- | --- | | 1 | C2,C12 | CAP, CER,1uF,6.3V,X5R, S0402 |   |   | | 2 | C3,C1 | CAP, CER, 22nF,16V, X7R, S0402 |   |   | | 3 | C9,C10,C11,C4,C5,C6,C7,C8 | CAP 100nF 1kV X7R C1812 | KEMET | C1812V104KDRACTU | | 4 | CON1,CON2,CON3 | CONN, EDGE PIN, 1MM | MILL-MAX | 3620-2-32-15-00-00-08-0 | | 5 | HSINK1 | HSINK, 33x33x33mm, Fin, 2.1C/W | MALICO | MBH375002-33P/2.6 | | 6 | IC1,IC2 | HEY1011 7.66 X10 MODULE, V03 | Heyday IC | HEY1011L12-PS | | 7 | J1 | Non Polarised 6Way Header 2P54 |   |   | | 8 | J2 | CONN, PTH,6POS, HDR, 2.54mm, Right Angle, Dual Row | SAMTEC | TSW-103-08-G-D-RA | | 9 | JP1 | CONN, HDR, 2WAY, SMT, PWR | KEYSTONE | 5102 | | 10 | Q1,Q2 | NGAN GS66508B 650V 30A | GaN Systems | GS66508B-E01-MR | | 11 | R1,R2 | RES, SMD, 10R, 0.063W, 1%, S0402 |   |   | | 12 | R3,R4 | RES, SMD, 1R0, 0.063W, 1%, S0402 |   |   | | 13 | R5 | RES, SMD, 100K, 0.063W, 1%, S0402 |   |   | | 14 | R7,R8 | RES, SMD, 0R0, 0.063W, 1%, S0402 |   |   | *Table 1: Bill of materials*   ## Double Pulse Test Results   *![HEY-HBDS-12C1-A fig11](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig11.png)* *Fig 11: HEY-HBDS-G-12C1-A Test set up*   | ![HEY-HBDS-12C1-A fig12](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig12.png) CH1(Red): Low side Vgs (1Ghz BW) CH2(Grn): Switch Node (500MHz BW) CH3(Blk): Inductor current (1A/V) | | --- | | Overview Vin = 400V |     ### DPT: RPU/RPD = 10R/1R | ![HEY-HBDS-12C1-A fig13a](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig13a.png) CH1(Red): Low side Vgs (1Ghz BW) CH2(Grn): Switch Node (500MHz BW) CH3(Blk): Inductor current (1A/V) | ![HEY-HBDS-12C1-A fig13b](https://www.heyday-ic.com/hubfs/0-resources/users%20guide/HEY-HBDS-12C1-A/HEY-HBDS-12C1-A%20fig13b.png) CH1(Red): Low side Vgs (1Ghz BW) CH2(Grn): Switch Node (500MHz BW) CH3(Blk): Inductor current (1A/V) | | --- | --- | | **Vin = 400V** | **Vin = 400V** |   ## Ordering information Please visit our [online store](https://bgouverneur.ovh/online-store)   ## Disclaimer Heyday Integrated Circuits (“Heyday”) provides all data in any resource and in any format such as, but not limited to datasheets, reference designs, application notes, web tools and safety information “as is” and with all faults, and disclaims any type of warranties, fitness for a particular purpose or non-infringement of 3rd party intellectual property rights.
