Electronically implemented dynamic start up method for ports with inrush current limiting functionality

An electronically implemented dynamic successive start up method for use with ports having a heat generating inrush current limiting functionality associated therewith, the method comprising:

• inputting at least one indication of temperature;
• comparing said at least one temperature indication with maximum;
• activating, only in an event said temperature indication does not exceed said maximum, power to a first port having associated therewith the heat generating inrush current limiting funtionality;
• and
• delaying a time period dependent on said at least one indication of temperature,
• whereby activating power to a second port having associated therewith the heat generating inrush current limiting functionality is permitted only after said delayed time period.

An electronically implemented dynamic successive start up method for use with ports each having a heat generating inrush current limiting functionality associated therewith, the method comprising:

• inputting at least one indication of temperature;
• comparing said at least one indication of temperature with a pre-determined maximum,
• in the event that said at least one indication of temperature does not exceed said maximum, activating power to a first port;
• having associated therewith the heat generating inrush current limiting funtionality;
• and
• delaying a time period dependent on said at least one indication of temperature,
• whereby activating power to a second port having associated therewith the heat generating inrush current limiting functionality is permitted only after said delayed time period.

A power over Ethernet controller comprising:

• control circuitry;
• at least one temperature sensor operatively connected to said control circuitry;
• and
• a plurality of electronically controlled switches responsive to said control circuit, each of said electronically controlled switches enabling power to a respective port and having associated therewith inrush current limiting functionality, said control circuit being operative to:
• input at least one indication of temperature from said at least one temperature sensor;
• operate at least one of said plurality of electronically controlled switches thereby enabling power to a first port;
• and
• delay a time period dependent on a function of said at least one temperature indication and at least one of package type, die heat conduction parameters and the presence or absence of heat conductive adhesive,
• whereby operation of a second of said plurality of electronically controlled switches to enable power to a second port is permitted only after said delayed time period.
