Abstract
Power delivery systems and methods are provided. A power delivery system (100) can include a thermal device (140) disposed at least partially within the external power delivery device (110). The thermal device can be configured to output a first signal (150) corresponding to an internal temperature of the power delivery device when the internal temperature of the power delivery device exceeds a predetermined threshold.
Claims14
A power delivery system comprising:
- a thermal device disposed at least partially within an external power delivery device, the thermal device configured to output a first signal having at least one parameter indicative of an internal temperature of the power delivery device when said internal temperature exceeds a predetermined threshold;
- and
- a power monitor to provide a second signal having at least one parameter indicative of a power output of the external power delivery device when the power output exceeds a level corresponding to a reference threshold, the reference threshold inversely related to the first signal.
A method, comprising:
- generating via a thermal device a first signal having at least one parameter indicative of an internal temperature of an external power delivery device when said internal temperature exceeds a predetermined threshold;
- reducing the power consumption of a remote device coupled to the external power delivery device by an amount related to the at least one first signal parameter;
- measuring a power output of the external power delivery device;
- generating a second signal having at least one parameter indicative of the power output of the external power delivery device when the power output exceeds a level corresponding to a reference threshold, the reference threshold inversely related to the first signal;
- and
- reducing the power consumption of the remote device by an amount corresponding to the at least one second signal parameter.

A power delivery system, comprising:
- thermal device including a negative temperature coefficient (NTC) thermistor, the thermal device disposed proximate to at least one internal component of an external power delivery device and configured to generate a first signal having at least one parameter indicative of an internal temperature of the external power delivery device when the internal temperature exceeds a predetermined threshold;
- and
- a power monitor configured to generate a second signal having at least one parameter indicative of a power output of the external power delivery device, when the power output exceeds a level corresponding to a reference threshold, the reference threshold inversely related to the first signal.
