Abstract
An integrated current sensor is provided in the present invention. The integrated current sensor includes: a conductor comprising at least one current input pin, at least one current output pin, a first leg portion connected to the at least one current input pin, a second leg portion connected to the at least one current output pin, and a connection portion connected between the first leg portion and the second leg portion; a magnetoresistive sensing and signal processing unit; an isolation unit configured to be sandwiched between the magnetoresistive sensing and signal processing unit and the conductor; a plurality of signal pins configured for being coupled to the magnetoresistive sensing and signal processing unit via wires respectively; and a package body configured for wrapping part of the conductor, part of the signal pins, the isolation unit and the magnetoresistive sensing and signal processing unit. A direction of current on the first leg portion is opposite to a direction of current on the second leg portion. The signal pins, the at least one current input pin and the at least one current output pin are exposed from the package body. In this way, the integrated current se…
