摘要（英）：

The utility model discloses an impedance detection circuit comprising an oblique ascension current generation circuit and an impedance determination circuit; the oblique ascension current generation circuit is used for inputting the oblique ascension current having N interruptions to a port, connected with an external device, of the self-equipment; the impedance determination circuit is used for detecting the impedance of the external device in each interruption time period of the oblique ascension current inputted by the oblique ascension current generation circuit, and until the impedance of the external device is detected in the last interruption time period of the N interruptions. The utility model also simultaneously discloses an integrated circuit.
