Abstract

The invention discloses a current sensing chip, and the chip comprises a substrate which is provided with a first surface and a second surface which are opposite to each other; the lead frame is used for guiding current on the outer side of the first surface and / or the second surface of the substrate to form a current path; the magnetic field transducer is arranged on the first surface of the substrate or on one side of the first surface; wherein the lead frame is at least provided with a surrounding part used for partially surrounding the magnetic energy transducer, and the surrounding part is configured to be provided with an opening, so that the magnetic energy transducer is at least partially exposed out of the surrounding part at least in a preset direction; the magnetic field transducer is an integrated circuit device made of at least a compound semiconductor. The current sensing chip has the beneficial effect that the detection sensitivity of the current sensing chip is improved based on the improvement of the structure and the material.

Description

technical field [0001] The present application relates to a current sensing chip. Background technique [0002] As is known in the art, a conventional current sensing chip employs a magnetic field transducer (eg, a Hall effect transducer or a magnetoresistive transducer) positioned adjacent to an electrical conductor. The amplitude of the output signal generated by the magnetic field transducer is proportional to the induced magnetic field of the current flowing through the conductor. [0003] Existing current sensing chips have defects such as low sensitivity due to structural and material problems. Contents of the invention [0004] The Summary section of this application serves to introduce concepts in a simplified form that are described in detail in the Detailed Description section that follows. The contents of this application are not intended to identify key features or essential features of the claimed technical solution, nor are they intended to limit the scope ...
