Integrated Current Sensor using Giant Magneto Resistive (GMR) Field Detector for Planar Power Module
… power modules have limited application for high-current operation, mainly because of their poor thermal management capability. Planar power modules have excellent thermal management capability and lower parasitic inductance, which means that the planar packaging method is desirable for high-power …
