DRV7308: Higher continuous output

Hello,

Thank you for your question! Since 1kW is significantly higher than the 250W target application of the device, I don't believe it would be achievable even with a heatsink. However, we always welcome feedback as we consider future devices, so I would love to hear a little more about your requirements. What would be the RMS current expected in your system? How about the peak currents? What operating voltage would this be used at?

Additionally, if you ok with considering 3 separate half bridge drivers, we might have some half bridge integrated GaN drivers available that might be able to support your requirements.

Hi.

Thanks for the quick response ,

Please give me time to summarize our requests, though they include things that are under consideration.

And It is difficult to post the usage and details on a public thread because they are confidential to the company,
Is it possible to contact you directly by some secure means or email?

These may be useful to some other users, so could you please post them as relevant information.

Thank you in advance.

Hi Yamamoto-san,

Understood, we can put you in contact with a member of our team to discuss the details of the project further. 

Regarding the half bridge integrated GaN drivers, you can find the product family here: https://www.ti.com/power-management/power-stages/gallium-nitride-power-stages/overview.html?keyMatch=gan&tisearch=universal_search There are 2 half bridge GaN capable of up to 650V abs max: The LMG2610 and LMG2650. Additionally, there are some lower voltage GaN options as well in the family.
