摘要： An electronic device includes one or more multinode pads having two or more conductive segments spaced from one another on a semiconductor die. A conductive stud bump is selectively formed on portions of the first and second conductive segments to program circuitry of the semiconductor die or to couple a supply circuit to a load circuit. The multinode pad can be coupled to a programming circuit in the semiconductor die to allow programming a programmable circuit of the semiconductor die during packaging. The multinode pad has respective conductive segments coupled to the supply circuit and the load circuit to allow current consumption or other measurements during wafer probe testing in which the first and second conductive segments are separately probed prior to stud bump formation.

摘要： 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.

摘要： In examples, a package comprises a semiconductor die having a device side and a bond pad on the device side, a conductive terminal exposed to an exterior of the package, and an electrical fuse. The electrical fuse comprises a conductive ball coupled to the bond pad, and a bond wire coupled to the conductive terminal. The bond wire is stitch-bonded to the conductive ball.

摘要： A leadframe includes leads or lead terminals, a plurality of folded features including i) support features positioned within an area defined in at least one dimension by the leads or the lead terminals configured for supporting at least one of a die pad and a first pad and a second pad spaced apart from one another, or ii) current carrying features. At least one of the folded features includes a planar portion and a folded edge structure that curves upwards at an angle of at least 45° relative to the planar portion. The folded features are configured to provide an effective increase in thickness to reduce the deformation observed in assembly.

摘要： 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.
