Method and apparatus for surface and ambient temperature estimation for portable devices
The surface temperature of a portable device is estimated. A sensor detects the internal temperature of the portable device. The internal temperature and an ambient temperature are used as input to a circuit model that describes thermal behaviors of the portable device. Dynamic thermal management may be performed based on the estimated surface temperature.
