Abstract

See full text

Current sensor packages are described including a leadframe configured to carry a current to be sensed and a current sensor that is electrically isolated from the leadframe. The current sensor is disposed adjacent to a first portion of the leadframe that includes a plurality of notches. An encapsulating material 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. The current sensor includes 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 are disposed on opposite sides of a central axis of the first portion of the leadframe.
