Thermal management techniques in an electronic device

An electronic device comprising:

• a temperature sensor at a first location of a device that is remote from a second location of the device;
• and
• a thermal manager to process a plurality of temperature readings from the temperature sensor to obtain a plurality of processed temperature readings associated with the second location,
• the thermal manager to (a) convert the processed temperature readings into estimates of temperature at the second location using a predefined mathematical relationship between an estimated target location temperature variable and a processed temperature reading variable, (b) compare the estimates to a desired temperature for the second location to determine errors, and (c) determine whether or not to apply a predefined, power consumption action that would reduce the errors.

A method for thermal management of an electronics device, comprising:

• estimating a temperature of a target location that is a battery hot spot or back case of the device using a temperature sensor that is at a remote location from the target location, by
• (a) filtering a sequence of temperature readings from the temperature sensor that is at the remote location in the device, and
• (b) using one of the filtered temperature readings to access a look up table, that lists temperature thresholds and corresponding power consumption commands, and thereby identify a power consumption command associated with a component of the device,
• wherein the look up table correlates temperature at the temperature sensor with temperature at the target location in the device, and further wherein the corresponding power consumption commands include a plurality of no change commands and at least one change command that limits or reduces power consumption of a component in the device to achieve thermal mitigation at the target location.
