<P>PROBLEM TO BE SOLVED: To provide a power source management device wherein when the voltage output of a power source is anomalous, it is possible to avoid damage to elements, such as LSI, connected to each power source. <P>SOLUTION: The power source management device includes: a control means 1A for controlling power sources 1 to 4; and power source supply means 9, 10, 11, 12 respectively provided for the power sources 1 to 4. The power source supply means output the voltages of the power sources 1 to 4 based on control signals 23, 25, 27, 29 output from the control means 1A and, when the voltages are normally output, output OK signals 24, 26, 28, 30 to the control means 1A. When the OK signal is not output from any power source supply means within a predetermined time, the control means 1A controls that power source supply means to interrupt all of the power sources 1 to 4 so that power is not supplied from any of the power source supply means 9, 10, 11, 12. <P>COPYRIGHT: (C)2011,JPO&INPIT |
