  • Power supply system compatible with multiple communication interface specifications and power receiver circuit thereof
    Patent number: 10840697
    Abstract: A power supply system includes a power supplier circuit and a power receiver circuit. The power supplier circuit supplies a power via a communication interface compatible with a first communication interface specification or a second communication interface specification. The first communication interface specification includes a delay threshold. After the power supplier circuit is coupled to the power receiver circuit, the power supplier circuit supplies the power after a first delay period. The power receiver circuit confirms whether the power supplier circuit is coupled to the power receiver circuit via a coupling confirmation step according to the first communication interface specification. The power receiver circuit confirms whether the power supplier circuit is compatible with the first communication interface specification or the second communication interface specification according to whether the first delay period is greater than the delay threshold.
