SEMICONDUCTOR DEVICE AND CONTROL SYSTEM

A semiconductor device includes first and second isolators, a first transmitting circuit that transmits a transmission signal via the first isolator, a first receiving circuit that receives a received signal corresponding to the transmission signal via the first isolator, an output driver that outputs a drive signal for driving a power device based on the received signal, a timer that inputs first and second signals having first and second information associated with the power device, respectively, and outputs a third signal from the first and second information, a second transmitting circuit that transmits the third signal via the second isolator and a second receiving circuit that receives a signal corresponding to the third signal via the second isolator.
