LMT87-Q1 VDD layout

Hello,

 

Datasheet explain “11.2 Layout Example” and 3 VDD are connected to power plain.

But I need to connect only 1 VDD to power plane like attached file because of layout restriction.

 E2E_LMT87-Q1.pptx

Please advise the influence in case of only 1 VDD is connected to power plane and remaining 2 VDD are open.

 

Best Regards.

  • Hi Ushikubo-san,

    All VDD pins must be connected to you system VDD. You don't necessarily need to connect them to the VDD power plane. You could route traces underneath the LMT87 to connect to these pins VDD pin that is connected to the VDD plane with the feedthrough. These additional pins must not be left floating. If they are left floating the part will not work properly.

    I hope this helps,
