<p><P>PROBLEM TO BE SOLVED: To suppress influence of temperature change in a power supply control device, electronic equipment, and a power supply control program. <P>SOLUTION: A power supply circuit 203 controls power supply to a control IC for which sequence and timing of supply by a plurality of power supplies are preliminarily determined. The power supply circuit 203 includes a delay time managing register 311 that stores delay time information indicating a time period from detection of a PGOODn signal indicating that power is supplied to the control IC from one power supply among the plurality of power supplies until start of power supply from a next power supply; and a control logic circuit 313 that detects an ENn signal, determines whether the time period indicated by the delay time information has elapsed since the detection of a PGOODn-1 signal, and outputs the ENn signal for making the next power supply start to supply power when it is determined that the time period has elapsed. The control logic circuit 313 detects the PGOODn signal that indicates that power is supplied after supply has started by the next power supply with the output ENn signal as a trigger. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
