  • Multiple sensor thermal management for electronic devices
    Patent number: 7887235
    Abstract: A device includes a current source circuit to separately provide a first current and a second current and a thermal detection device coupleable to the output of the current source circuit. The device further includes a voltage detection circuit to provide a first indicator of a first voltage representative of a voltage at the thermal detection device in response to the second current and a second indicator of a second voltage representative of a voltage difference between the voltage at the thermal detection device in response to the second current and a voltage at the voltage detection device in response to the first current. The device further includes a temperature detection circuit to provide an over-temperature indicator based on the first indicator and the second indicator, wherein an operation of a circuit component of the device can be adjusted based on the over-temperature indicator.
