Abstract
According to one embodiment, a degradation detection device includes a driving circuit that supplies a driving signal that controls on/off of an output transistor to the output transistor and an output circuit that compares a value of integral of an output current that is output by the output transistor in an off-state thereof over a predetermined period of time with a predetermined threshold when the output transistor is turned from an on-state thereof to an off-state thereof and outputs a signal that indicates a degradation state of the output transistor depending on a result of such comparison.
