Abstract
A current sensor integrated circuit configured to sense a current through a current conductor includes a lead frame at least one signal lead, a fan out wafer level package (FOWLP), and a mold material enclosing the FOWLP and a portion of the lead frame. The FOWLP includes a semiconductor die configured to support at least one magnetic field sensing element to sense a magnetic field associated with the current, wherein the semiconductor die has a first surface on which at least one connection pad is accessible, a redistribution layer in contact with the at least one connection pad, and an insulating layer in contact with the redistribution layer, wherein the insulating layer is configured to extend beyond a periphery of the semiconductor die by a minimum distance. The die connection pad is configured to be electrically coupled to the at least one signal lead.
