Si8239x-EVB User s Guide The Si8239x isolated gate drivers are ideal for driving power switches used in a wide va- KEY FEATURES riety of power supply, inverter, and motor control applications, offering longer service life and dramatically higher reliability compared to opto-coupled gate drivers. The Si8239x Screw terminals for easy connection to isolated gate drivers utilize Silicon Laboratories proprietary silicon isolation technology power supplies supporting up to 5 kVRMS withstand voltage per UL1577 and VDE0884. This technolo- Test points on each pin for easy connection gy enables industry-leading common-mode transient immunity (CMTI), tight timing spec- to test equipment ifications, reduced variation with temperature and age, better part-to-part matching, and Boot strap circuitry selectable by jumper very high reliability. It also offers unique features, such as driver shutdown on UVLO fault and precise dead time programmability. Driver outputs can be grounded to the Jumpers for easy manual control of input signals same or separate grounds or connected to a positive or negative voltage. The extended range inputs (2.5 to 5.5 V) are available in individual control input (Si82390/1/5/6/7) or PWM input (Si82394/8) configurations. High integration, low propa- gation delay, small installed size, flexibility, and cost-effectiveness make the family ideal for a wide range of isolated MOSFET/IGBT gate drive applications. The Si8239x evaluation board allows designers to evaluate Silicon Lab s Si8239x family of ISOdrivers. Screw terminals are provided to allow for quick evaluation of the devices key parameters. Test points are also included on each of the devices pins to accommo- date direct connection to the designers end system. In addition, jumpers are included to allow for manual setting of the devices input as well as the boot strap circuitry on the output if desired. The boards come populated with the Si82394 version of the family. However, JP2 (VIB) is still provided should the user wish to replace the Si82394 with one of the dual input versions of the device.
