摘要：A power supply control circuit is connected to and controls a system powersupply IC. The system power supply IC has multiple power supply circuits and is capableof outputting multiple power supply voltages. The system power supply IC activates themultiple power supply circuits at one time using a common enable signal. The power
supply control circuit includes a gate circuit and a first switch unit. The gate circuitgenerates the common enable signal based on a control signal and a selection signal.The control signal is output from a control device during a usual operation. The selectionsignal is a signal that selects one of the multiple power supply circuits which is requiredto output the power supply voltage. The first switch unit is driven by a power-on signalduring system activation, and switches on or off the selection signal input to the gatecircuit.
