Important Precautions

Caution: Handling devices with high voltages involves risk to life. It is imperative to

comply with all respective precautions and safety regulations.

When installing the ribbon cable, please make sure that power is turned off. Multi-signal values are sent

along this ribbon cable, thus hot swapping may cause damage to the IC components on the board.

AgileSwitch assumes that the gate drive board has been mounted on the SiC MOSFET prior to start-up

testing. It is recommended that the user checks that the SiC MOSFET power modules are operating inside

the Specified Operating Area (SOA) as specified by the module manufacturer including short circuit testing

under very low load conditions.

Recommended Start-Up Testing

1. Connect the driver through the 20 pin control header to your drive electronics and supply the driver with

+15V.

2. Send the fault reset pin, pin 19, a low signal. Return pin 19 to a high condition. (If the driver is configured for

Auto Reset, you may ignore this step.)

3. Check the gate voltage:

a) For the off-state, the nominal gate voltage should be -6V to -4V. (Note 3)

b) For the on state, it is +17 to +21V. (Note 3)

c) Check that the supply current of the driver is within spec with inactive trigger signals and then at the

desired switching frequency.

4. The system is now ready for application testing under load conditions.

5. Check thermal conditions to verify that the system is operating within specified temperature range.

6. Do NOT apply High Voltage to the SiC Module without first applying power to the GDB.
