    摘要： There is provided a power transmission control device included in a power transmission device in a contactless power transmission system that transmits power from the power transmission device to a power receiving device by electromagnetically coupling a primary coil to a secondary coil to supply the power to a load of the power receiving device. The power transmission control device includes a controller controlling the power transmission control device, a host interface communicating with a power transmission-side host, and a register section accessible from the power transmission-side host via the host interface. The controller shifts into a communication mode that executes communication between the power transmission-side host and a power receiving-side host, when the power transmission-side host writes, via the host interface, a communication request command that requests the communication between the hosts in the register section. Then, the controller transmits the communication request command to the power receiving device.

The waveform monitoring circuit includes a first rectifier circuit having a limiter function, the first rectifier circuit including a current-limiting resistor provided between a coil end node where the coil end signal of the primary coil is generated and a monitoring node where the waveform-monitoring induced voltage signal is generated, performing a limiter operation that clamps the induced voltage signal at a high-potential-side power supply voltage, and subjecting the induced voltage signal to half-wave rectification.
