  • Patent number: 11782466
    Abstract: To dynamically manage a temperature of an electronic device, a local temperature is provided by measuring a temperature of a local spot in the electronic device and a reference temperature is provided by measuring a temperature of a reference spot in the electronic device where the reference spot and the local spot are thermally coupled. A target temperature corresponding to a limit value of the reference temperature is adjusted based on the local temperature and a power level of the electronic device is controlled based on the same target temperature. The target temperature may be set to a relatively high value to secure performance of the electronic device when the local temperature is relatively low. Alternatively, the target temperature may be set to a relatively low value to pursue stability of the electronic device when the local temperature is relatively high.

  • Publication number: 20230261657
    Abstract: In a transistor turnoff system, a transistor control circuit is configured to adjust a control voltage at a transistor control output responsive to a comparison signal at a control input. The control voltage has a slew rate. A comparator has a comparator output and first and second comparator inputs. The first comparator input is coupled to the transistor control output. The comparator is configured to: provide the comparison signal at the comparator output based on a reference voltage at the second comparator input; and deactivate the transistor control circuit by changing a state of the comparison signal responsive to the control voltage falling below the reference voltage. A slew-rate compensator is configured to increase the reference voltage by a compensation voltage that compensates for a time delay of the comparator or the transistor control circuit. The compensation voltage is proportional to the slew rate.
