Hall sensor is a magnetic field sensor made according to Hall effect. Hall effect is a basic method to study the properties of semiconductor materials. The Hall coefficient measured by Hall effect experiment can judge the important parameters of semiconductor materials, such as the conductive type, carrier concentration and carrier mobility. It is sensitive to magnetic field, simple in structure, small in size, wide in frequency response, large in output voltage variation and long in service life. Therefore, it is widely used in measurement, automation, computer and information technology.
SPARC Semiconductors is a Semiconductor IDM,it founded in 2018.headquartered in Wuxi / China, focusing on Sensors, Power, Analog & RF Components. It is part of and stands for Smart Sensors System is committed to the sensor uses IATF16949 certified internal FAB with mature processeshas Backside-vertical Hall technology, which grants our 2D/3D Hall sensors an outstanding performance.

Hall Current Sensor Product---SCHCSAA

Hall current sensor SCHCSAA has the advantages of miniaturization and high cost efficiency, no magnetic core or shielding is required, and the assembly is simple and flexible. 
TheSCHCSAAcan be used directly on top ofPCB or Bus Barprimary current conductor and detects the lateralmagnetic field generated by the primary current.The chip has two different Hall Sensor areas which can be configured inAdditive Mode (for maximumsensitivity enhancement)or inDifferential Mode (for additional stray field compensation).
