Abstract:
A packaged multichip isolation device includes leadframe including a first and second die pad, with a first and second lead extending outside a molded body having a downward extending lead bend near their outer ends. A first integrated circuit (IC) die on the first die pad has a first bond pad connected to the first lead that realizes a transmitter or receiver. A second IC die on the second die pad has a second bond pad connected to the second lead that realizes another of the transmitter and receiver. An isolation component is in a signal path of the isolation device including a capacitive isolator, or inductors for transformer isolation on or between the die. A midpoint of the thickness of the die pad is raised above a top level of the leads and in an opposite vertical direction relative to the downward extending bend of the external leads.
