The MT9519 product series is a current IC that utilizes a built-in magnetic collector to convert a vertical magnetic field into horizontal magnetic dection (HMD). The traditional Planar Hall technology is only sensitive to the magnetic flux density applied perpendicular to the IC surface. The sensor IC using HMD technology is only sensitive to the magnetic flux density applied parallel to the surface of the IC. This is achieved by placing two pieces of magnetic conductive metal on the chip. This chip is a highly integrated Hall sensor IC that provides an output signal proportional to the magnetic flux density applied horizontally, making it suitable for current measurement. Due to its small size and use of SOP-8 package, it is very suitable as an open-loop current sensor for PCB or busbar installation. It is suitable for various current ranges from a few amperes to 1000 amperes or higher.
