Abstract
A semiconductor device includes a plurality of switching elements electrically connected in parallel with each other, a control unit that outputs a control signal for controlling a current supplied to each of the switching elements, and a temperature estimation unit that estimates a temperature difference between the switching elements. When an estimated temperature difference becomes equal to or higher than a predetermined threshold temperature, the control unit shifts an operation mode to a stop mode for stopping driving of a switching element having a temperature higher than the other.
