Abstract
A coupling device provides galvanic isolation using a leadframe that is configured to support two integrated circuit chips in a coplanar manner. Each chip contains an inductive coupling coil. The lead frame includes a set of bond pads for attaching bond wires to couple to the two integrated circuit chips. Two separated die attach pads support the two chips. Each die attach pad is configured to support one of the two integrated circuit chips with a plurality of cantilevered fingers.
