Abstract
A current sensor includes one or more inductors that generate a sensed output current responsive to a current in a conductor when the one or more inductors are inductively coupled to the conductor. The current sensor includes an integrated circuit die including an integrator circuit coupled to the one or more inductors for generating a sensed voltage responsive to the sensed current, the sensed voltage indicative of the first current in the conductor. The inductors may be formed in the integrated circuit and the conductor may incorporated into the package holding the die.
