7.2.2.1 Design Requirements

A push button that is made of flexible material has a conductive target attached to the underside and a contactless solution using the LDC0851 is required for reliability purposes. Determine the coil characteristics as well as the threshold adjust setting if the following conditions are true:

  1. The target is made of a conductive material, such as aluminum foil or copper tape
  2. The conductive target is circular and measures 10 mm in diameter
  3. The resting height of the conductive target is 2.5 mm above the PCB when no button push
  4. The maximum travel distance when pressed is 2 mm, leaving an airgap of 0.5mm above the PCB
