| 摘要 |
A semiconductor integrated circuit comprises a transistor which has a first electrode, a second electrode and a third electrode, said transistor conducting a current of a first power source from the second electrode to the third electrode by a power supplied to the first electrode; a driver to supply said first electrode with power for driving said transistor; a reference voltage circuit to generate a reference voltage which is variable in response to temperature of said transistor, said reference voltage being used as the reference for comparison; a comparative voltage circuit to generate a comparative voltage which is variable in response to a current flowing from said second electrode to said third electrode, said comparative voltage being compared with said reference voltage; and a controller which receives said reference voltage and said comparative voltage and which supplies a control signal to said driver, said control signal being based on a result of the comparison between the comparative voltage and the reference voltage to control the power supplied to said first electrode.
