FOD (Foreign Object Detection)

Condition

Preceived ｰ 250mW ≦ Ploss ≦ 0mW : WPC vol.1.1 Spec

FOD function is to calculate losses of received power.

In a wireless power supply system with the TC7761WBG it is possible to calculate power loss between

Tx coil and Rx coil from the difference between Tx emitted power and the received power reported by

the TC7761WBG.
