A method of supplying power to a system includes a power supply structure supporting a power over data line (PoDL) function. The method of supplying power comprises: a step of detecting a low voltage lower than a reference voltage; a step of determining whether a low voltage status is a temporary voltage drop status; a step of entering a settle sleep status when the low voltage status is not the temporary voltage drop status; and a step of stopping a power supply between PSE and PD, and maintaining a link if the low voltage status is the temporary voltage drop status. Accordingly, the present invention is able to improve stability of the power supply by considering an unstable power condition.

    파워 오버 데이터 라인(Power Over Data Line; PoDL) 기능을 지원하는 전력공급구조를 구비한 시스템에 전력을 공급하는 방법이 개시된다. 전력을 공급하는 방법은, 기준전압보다 낮은 저전압을 검출하는 단계, 저전압 상태가 일시적인 전압강하 상태인지를 판별하는 단계, 저전압 상태가 일시적인 전압 강하 상태가 아닌 경우 슬립준비(settle sleep)상태로 진입하는 단계, 저전압 상태가 일시적인 전압 강하 상태인 경우 상기 PSE와 상기 PD간의 전력 공급은 중단하고 링크는 유지하는 단계를 포함한다.
