Claim 0:
1. An apparatus, comprising:
a leadframe configured to carry a current to be sensed;
a current sensor that is electrically isolated from the leadframe, the current sensor being disposed adjacent to a first portion of the leadframe, the first portion including a plurality of notches that are formed therein, the current sensor including a substrate, a first magnetic field sensing element that is formed on the substrate, and a second magnetic field sensing element that is formed on the substrate, the first magnetic field sensing element and the second magnetic field sensing element being disposed on opposite sides of a central axis of the first portion of the leadframe and configured to sense the current; and
an encapsulating material that is configured to encapsulate the current sensor and at least a part of the first portion of the leadframe that is adjacent to the current sensor and includes the plurality of notches,
wherein the first portion of the leadframe is disposed between a second portion of the leadframe and a third portion of the leadframe, the first portion of the leadframe is formed in a same plane as the second portion of the leadframe and the third portion of the leadframe, and the first portion extends at an angle relative to the second portion and the third portion.
