Part Number: LMG3410R070

We know a press release for LMG3410r070, but I want to know detail different for 600V GaN module. It's D-MIS device on inside.

    Hi Sean,

    Thanks for reaching out to us, my name is Mamadou Diallo and I will help address your concern.

    Just so that I am clear, are you asking about the internal structure of the 600V GaN transistor used in LMG3410R070? Do you have specifics concerns that relate to your design?

    Thanks in advance for the clarification.

    Regards,

    Hello Sean,

    Thank you for your interest. Our LMG3410R070 is a D-mode device. But different from conventional cascode D-mode device, we are having a direct drive circuit to directly switch the device. There is no Si device switching when the module is powered on. Since this is a d-mode device, we have a Si device in series with it just to make sure it is normally off without any VDD power. However, it will be always on during switching.

    For more information regarding the operation this power stage, please look into our updated datasheet and let me know if you have any questions.

    Thanks and regards,

    I just want to know the difference between the newly introduced LMG3410r070 and the previous LMG3410? What is the function of this part number r70? If there is a comparison table, it is better.

    Hi Sean,

    Thanks for asking. Actually, the previous LMG3410 and the new part number LMG3410R070 are exactly the same part. Just to tell more information about the Rdson to people directly in the part number, we added the "R070" to attach to the original one. It means 70mOhm Rdson at room temp.

    Hope it helps.

    Thanks and regards,
