Abstract: An galvanic isolator circuit is provided. The electronic isolator circuit includes a coil and a magnetic field (MF) sensor. The coil is coupled to a first circuit. The MF sensor is coupled to a second circuit, and disposed corresponding to the coil. The first circuit transfers a MF signal to the MF sensor via the coil. The MF sensor transforms the MF signal into an output signal and provides the output signal to the second circuit. Accordingly, the galvanic isolator circuit is capable of realizing functions for galvanic isolating by utilizing the coil and the MF sensor.

Abstract: An electrical isolator packaging structure and a manufacturing method of an electrical isolator are provided. The electrical isolator packaging structure includes a first substrate, a second substrate, a coil, and a magnetic field (MF) sensor. The coil is disposed on the first substrate. The MF sensor is disposed on the second substrate. The position of the coil is arranged according to the position of the MF sensor such that the coil transmits a signal to the MF sensor. Thus, the electrical isolator can be implemented by magnetic coupling with the coil and the MF sensor.
