4.4.5 Gate drive resistors
•
RGH - gate high resistor in series with the GH pin at the output of the GD3160 gate
high driver and DCM
™
1000X module gate that controls the turn-on current for SiC
MOSFET gate.
•
RGL - gate low resistor in series with the GL pin at the output of the GD3160 gate low
driver and DCM
™
1000X module gate that controls the turn-off current for SiC MOSFET
gate.
•
RAMC - series resistor between SiC gate and AMC input pin of the GD3160 driver for
gate sensing and active Miller clamping.

1000X module.
It remains the responsibility of the user always to verify the operation within the safe
operating area (SOA) of the power module.
