INTEGRATED CURRENT SENSOR WITH MAGNETIC FLUX CONCENTRATORS

In one example, circuitry is formed in a semiconductor die. A magnetic concentrator is formed on a surface of the semiconductor die and over the circuitry. An isolation spacer is placed on a lead frame. The semiconductor die is placed on the isolation spacer, and the magnetic concentrator is aligned...

Zusammenfassung:	In one example, circuitry is formed in a semiconductor die. A magnetic concentrator is formed on a surface of the semiconductor die and over the circuitry. An isolation spacer is placed on a lead frame. The semiconductor die is placed on the isolation spacer, and the magnetic concentrator is aligned to overlap the lead frame. Electrical interconnects are formed between the semiconductor die and the lead frame.
