FAQ

What is the function of the internal gate resistor?

The internal series gate resistor limits the maximum switching frequency defined by the external gate resistance and prevents excessive dv/dt and di/dt rates.

How should the Kelvin sense pins be connected?

All source sense pins (SL1, SL2, SH1, SH2) and gate pins (GL1, GL2, GH1, GH2) should be connected directly to the gate driver circuits to ensure stable operation.

What is the isolation voltage rating?

The module has an isolation voltage rating of 4000 VAC when tested at I_ISOL < 1mA for 1 minute at 50/60 Hz.
