Title: VOLTAGE ADJUSTMENT FOR THERMAL MITIGATION
Abstract:
Apparatuses and methods to adjust voltage for thermal mitigation are provided. The apparatus includes a circuit, a plurality of switches configured to provide power of a power domain to the circuit, a plurality of thermal sensors disposed at different locations about the circuit and configured to detect temperatures at the different locations, and a control circuit configured to determine that one of the detected temperatures at one of the locations exceeds a temperature threshold, and in response, adjust one or more of the plurality of switches in proximity with the one location to reduce power provided to the circuit. The method includes providing power of a power domain through a plurality of switches, detecting a temperature at a location exceeding a temperature threshold, and adjusting the plurality of switches in proximity with the location to reduce the power provided, in response to the detecting the temperature exceeding the temperature threshold.
