Abstract:
A PSE configured to determine the end of the start up phase at the PD responsive to a condition of the voltage at the PSE output. In one particular embodiment, the startup phase end is determined responsive to a PSE output voltage within a predetermined range of the PSE input voltage. In another particular embodiment, the startup phase end is determined responsive to the voltage drop associated with the PSE current limiter being lower than a predetermined maximum. In yet another particular embodiment, the startup phase end is determined responsive to the absolute value of the rate of change of the PSE output voltage being lower than a predetermined value. In yet another particular embodiment, the startup phase end is determined responsive to the absolute value of the rate of change of the voltage drop associated with the PSE current limiter being lower than a predetermined value.
