The invention discloses electrical equipment, an integrated circuit's loop thereof and a circuit connecting method. The integrated circuit's loop includes: a passive component part, including a power device and/or an execution device; and one or more electrical components, each of the electrical components including a body and multiple pins, wherein at least one pin extends to an electrical connecting end of the passive component part, and is electrically connected with the electrical connecting end. In the integrated circuit's loop of the invention, the pins of the electrical components extend to electrical connecting ends of the passive component part, and are electrically connected with the electrical connecting ends, so that the electrical components are not required to be arranged on a Printed Circuit Board (PCB), a physical structure of the circuit configuration is simplified, a size of the circuit is reduced, and the technician is not required to design the PCB.
