Abstract:
1. A method for managing thermal energy generation in a portable computing device (“PCD”), the method comprising: defining temperature thresholds associated with one or more components in the PCD; monitoring one or more temperature sensors in the PCD, wherein each temperature sensor is associated with one of the one or more components and generates signals that represent an instantaneous temperature; tracking an instantaneous thermal resistance value associated with each of the one or more components, wherein the instantaneous thermal resistance value of a component is calculated from the instantaneous temperature of the component, an active power supply to the component and an ambient temperature of the PCD; determining that a temperature threshold associated with at least one of the one or more components has been exceeded; calculating an adjusted power supply for the at least one of the one or more components, wherein the adjusted power supply is calculated from a target temperature of the at least one of the one or more components, the ambient temperature of the PCD and the instantaneous thermal resistance value associated with the at least one of the one or more components; and applying the adjusted power supply to the at least one of the one or more components.
