Dynamic successive start up algorithm

A dynamic successive start up algorithm comprising:

• inputting at least one indication of temperature;
• activating power to a first port;
• and
• delaying a time period dependent on said at least one indication of temperature,
• whereby activating power to a second port is permitted only after said delayed time period.

A dynamic successive start up algorithm 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;
• and
• delaying a time period dependent on said at least one indication of temperature,
• whereby activating power to a second port 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.
