Abstract: Method and apparatus are provided for thermal management of mobile devices. In one novel aspect, a throttle method is used to control the fast rising temperature for the device. In one embodiment, the thermal management method determines a temperature of the mobile device and compares the temperature with a plurality of predefined temperature thresholds. The thermal management applies a first throttle solution upon detecting the temperature reaches a first predefined temperature threshold and applies a second throttle solution upon detecting the temperature reaches a second predefined temperature threshold. In one embodiment, the first and the second throttle solutions control the slope of the rising temperature to be below a first predefined slope and a second predefined slope, respectively. In one embodiment, the temperature is controlled by adjusting the operating frequency and/or voltage of at least one heat-generating component of the mobile device.

Abstract: Method and apparatus are provided for thermal management of mobile devices. In one novel aspect, a micro-throttle method is used to control the fast rising temperature for the device. In one embodiment, the thermal management method determines a temperature of the mobile device and compares the temperature with a plurality of predefined temperature thresholds. The thermal management applies a first micro-throttle solution upon detecting the temperature reaches a first predefined temperature threshold and applies a second micro-throttle solution upon detecting the temperature reaches a second predefined temperature threshold. In one embodiment, the first and the second micro-throttle solution control the slope of the rising temperature to be below a first predefined slope and a second predefined slope, respectively. In one embodiment, the temperature is controlled by adjusting the operating frequency or voltage of at least one heat-generating component of the mobile device.
