TIDA-00915: Testing TIDA-00915

Part Number: TIDA-00915

Hello

We are designing an inverter using LMG3410...we would like to get a version of TIDA-00915 to test it and compare it with our design. Is there any way we can purchase a physical version of TIDA-00915 from TI? If not can you refer us to any third party that sells a version of that reference design

Regards

Sam

  • Sam, hello and thanks for your continued interest in Texas Instruments. You query has been received, however, please note that the design owner from our Industrial Motor Drives team is out of the office on holiday vacation until Monday, January 7th. As is such, please expect a delayed response to your question until 1-2 business days thereafter.

    Hello Sam,

    thank you for your interest in the TIDA-00915 TI design. We won't sell or provide the TIDA-00915 hardware neither through TI nor a third party.

    However to allow customers build the hardware through a PCB manufacturer of their choice, we either provide the Gerber files or, if you have Altium PCB designer we provide the entire Altium CAD project. You can download these files under the TIDA-00915 design files folder.

    An alternative might be using three of the LMG3410R070 Daughter Cards (half-bride) to build your custom 3-phase inverter. Of course the daughter card does not include current sensing and you need to build an adapter board. You can get LMG3410R070 Daughter Cards (or the EVM) from the TI Store: www.ti.com/.../lmg3410-hb-evm

    Dear Martin

    Thanks for your clear answer.

    In regard to the use of LMG3140-70.....we believe we should be able to use about 62 thermal vias under each device (in a pattern similar to the one used in TIDA-00915)….and this way the size of the heat sink will be much reduced......do you agree?.....If so why did not you do that in TIDA-00915?....is that only because thermal via cost more...or is there other reason

    Regards

    Sam

    Hello Sam,

    yes, your comments on the thermal vias for LMG3410 are fully correct. The TIDA-00915 layout is not optimum at all and we should have added these vias. For LMG3410 layout, I'd much recommend follow the LMG3410 EVM/daughter card and recommendations in the LMG3410 data sheet.
