Abstract:
A Hall-effect sensor package includes and an IC die including a Hall-Effect element and a leadframe including leads on a first side providing a first field generating current (FGC) path including ≥1 first FGC input pin coupled by a reduced width first curved head over or under the Hall-effect sensor element to ≥1 first FGC output pin, and second leads on a second side of the package. Some leads on the second side are attached to bond pads on the IC die including the output of the Hall-effect element. A clip is attached at one end to the first FGC input pin and at another end to a location on the first FGC output pin, having a reduced width second curved head in between that is over or under the Hall-effect sensor element opposite the first head.
