Part Number: LMG3422R030 Tool/software: Hi Team,
Customer feedback that FAULT pin will take wrong action under 68kohm resistor of RDRV, and if this resistor reduce to 47kohm, it will disappear.
It is abnormal. I only have the experience of high gate driver…
I probed the FAULT pins, the OC pins and the Switch node, I found that the bottom FET is throwing a fault on the FAULT pin.
The Top FET fault pins and OC pins are all good with no issues.
Here is the switch node waveform:
NOTE: This is in the unloaded…

Dear Team,
I am currently working on designing an inverter using the LMG3422R030 GaN FET and have some doubts regarding its implementation…
Part Number: LMG3422R030 Other Parts Discussed in Thread: LMG3422EVM-043 Tool/software: also could you please confirm why there is low pass filter at the output of fault and overcurrent signals for the top fet and not for the botttom fet, how do i sense…
Part Number: LMG3422R030 Tool/software: Hello,
we are also interessed in connecting GaN-Devices in parallel for high current hard switching application.
Can you please send me the documentation, which is explained in the following thread:

Hi Raja,
1. Try connecting the LDO5V cap without any series resistor. If this does not work, try removing the high-side device and simply replace it with a diode rectifier. This will allow you to characterize the low-side device.
2. Per Figure 5-4, a lower…
