Si8239x-EVB User's Guide The Si8239x isolated gate drivers are ideal for driving power switches used in a wide variety of power supply, inverter, and motor control applications, offering longer service life and dramatically higher reliability compared to opto-coupled gate drivers. The Si8239x isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolation technology supporting up to 5 kVRMS withstand voltage per UL1577 and VDE0884. This technology enables industry-leading common-mode transient immunity (CMTI), tight timing specifications, reduced variation with temperature and age, better part-to-part matching, and 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 same or separate grounds or connected to a positive or negative voltage. KEY FEATURES • Screw terminals for easy connection to power supplies • Test points on each pin for easy connection to test equipment • Boot strap circuitry selectable by jumper • Jumpers for easy manual control of input signals 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 propagation 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 device’s pins to accommodate direct connection to the designer’s 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.

Verify the 3.3 V power supply output before connecting to EVB. Disable supply output before connecting to evaluation board. 2. Connect the positive rail of the 3.3 V supply to J1 pin 1 (labeled VDDI) or to TP1. 3. Connect the negative rail of the 3.3 V supply to J1 pin 2 (labeled GNDI) or TP4. 4. Turn ON the 3.3 V supply. 5. Verify the 15 V power supply output before connecting to EVB. Disable supply output before connecting to evaluation board. 6. Connect the positive rail of the 15 V supply to J2 pin 3 (labeled VDDA) or to TP9. 7. Connect the negative rail of the 15 V supply to J2 pin 1 (labeled GNDA) or TP11. 8. Turn ON the 15 V supply. 2.2 Test Channel A 1. Add shunt between pins 1 and 2 on JP1 and JP3. 2. Using the DMM verify a logic 1 on TP10 with respect to TP11 (POS on TP10, NEG on TP11). 3. Move shunt to pins 2 and 3 on JP1. 4. Using DMM, verify logic 0 on TP10 with respect to TP11. 2.3 Test Channel B 1. Turn off 15 V supply. 2. Move the 15 V positive rail to J3 pin 3 or TP14. 3. Move the 15 V negative rail to J3 pin 1 or TP15. 4. Turn on 15 V supply. 5. Using DMM, verify a logic 1 on TP13 with respect to TP15. 6. Move the shunt on JP1 back to pins 1–2. 7. Using DMM, verify a logic 0 on TP13 with respect to TP15. Note: A signal generator can be used to supply a clock signal to JP1 pin 2 instead of using the shunt. silabs.com | Smart. Connected.
