Dear sir

Where can we locate footprint?WQFN24.

also let us know how to go for the LC tank design testing with chip?

Where can we locate MSP430 evb with single wire interface.

Hello Seema,

The footprint for the WQFN device is located at the end of the datasheet.

The LC tank design is normally done by the customer that is using the LMP91300. There is information on the ti.com

There is information about LC tank design using a PCB coil at the Webench design page: www.ti.com/.../inductive-sensing.page

Please contact Tarig Chang at tchange@ti.com about the availability of a SWIF EVM.

Hi Seema,

I'm sorry, I do not see your email regarding this request. Do you have a local TI sales contact that calls on your company or a distribution contact that you work with in your region? Unfortunately, we are unable to ship directly to the customer due to shipping policies.

Thanks,

Tarig

Yes Tarig
We contact
Joshi, Heman <hemanjoshi@ti.com>
You can forward the require through his help.
We have requirement for inductive proxy switch for defense, We have stated board design with LMP91300.received samples.
Need the GUI & board for programming LMP91300 also need sample for LDC reference coil board for trials.
regards

Hi Seema,

Thanks for the contact, I've reached out to your local sales rep to coordinate the delivery of this GUI and board for programming the LMP91300.
Please let me know if there are any further issues regarding the delay of the boards.

In addition, I was curious if you've also taken a look at the LDC0851 to see if this would be a suitable device for your application. This device does not require programming and automatically compensates temperature drift through a differential measurement.

Thanks,
Tarig

Dear Tarig,

Thanks for co operation.
As per specification input maximum input voltage specified is >30V,which leaded us to select the LPM91300.

Can we use the H,I,K coils to test the design for the 4 mm proximity from LDC coil board which has resonating Frequency between 5K to 5Mhz ?

Can you be able to provide samples for reference coil board also?

Thanks & regards
Seema Joshi

Hi Seema,

What do you mean by H, I and K coils?

Were you able to answer the email that Tarig sent you with the information he needs?

Hello Seema,
are you referring to the LDCCOILEVM from the e-store? www.ti.com/.../snou136.pdf

Dear Mike,

yes i have forwarded the contacts from TI FAE at our area to Tirag its hemanjoshi@ti.com and jatin.b@ti.com

Yes we are referring to the LDCCOILEVM from the e-store?

Hello,

Yes, you can use the H, I and K coils. For the H coil you will want to pick the C so that it oscillates at about 500kHz. The I coil should oscillate at 200kHz to 250kHz and the K coil should be at about 500Khz.
