Abstract
Methods and apparatus for providing a high isolation current sensor. In embodiments, a current sensor includes a leadframe having a current conductor first portion and a second portion, a magnetic field sensing element positioned in relation to the current conductor for detecting a magnetic generated by current flow through the current conductor, and a die supported by at least a portion of the first and/or second portions of the leadframe, wherein the first portion of the lead frame includes an isolation region aligned with a first edge of the die. In embodiments, a current sensor includes SOI processing and features to enhance active layer isolation.
