Abstract:
A current sensor includes a coils located within the integrated circuit die and inductively coupled to a conductor located in the integrated circuit package holding the die. The inductors sense the current in the conductor and supply the sensed signal to an integrator that supplies a voltage indicative of the current in the conductor.
