WEBENCH® Tools/LDC1101: Coil designer like as WEBENCH® Designer LDC1000

Hirotaka Matsumoto

Part Number: LDC1101
Other Parts Discussed in Thread: LDC1612

Tool/software: WEBENCH® Design Tools

Hi all

Would you mind if we ask LDC1101?

We would like to simulate PCB coil of LDC1101 with WEBENCH® Designer.
LDC1101 does not correspond to WEBENCH® Designer.
Is it possible to simulate PCB coil of LDC1101 with WEBENCH® Designer?

As our request, we would like to judge whether it is possible to detect(read) transition amount(0mm upto 1mm) using LDC1101.

<Content>
-Target distance : 4mm～6mm
-Target metal : 8mm x 15mm x 3mm(thickness)
-The space of PCB coil footprint : 10mm x 10mm
-Transition amount of target metal : 0～1mm
 
Kind regards,

Hirotaka Matsumoto

    Hello Matsumoto-san,
    you can design a coil for the LDC1101 by selecting the LDC1000 or LDC1612 in the Webench coil designer. The coil design is the same, but the design space is slightly different (oscillation frequency and RP). Alternatively, you can use the LDC calculator tool (www.ti.com/.../getliterature.tsp which does support the LDC1101 and its boundary conditions. The Spiral_Inductor_Designer tab shows the frequency shift that you will get by moving an Aluminum target from one distance to another while automatically displaying a warning if the device boundary conditions are violated.
