Abstract: Methods and apparatus for a signal isolator having enhanced creepage characteristics. In embodiments, a signal isolator IC package comprises a leadframe including a die paddle having a first surface to support a die and an exposed second surface. A die is supported by a die paddle wherein a width of the second surface of the die paddle is less than a width of the die.

Abstract: Methods and apparatus for an integrated circuit having first and second domains with an insulative material electrically isolating the first and second domains. A conductive shield is disposed between the first and second domains and a current sensor has at least one magnetoresistive element proximate the shield to detect current flow in the shield due to breakdown of the insulative material.
