| 摘要 |
A discharge circuit for a decoupling capacitor to stabilize a voltage supplied from a first power supply unit to a first load includes a first capacitor, a first switch, and a discharge control circuit. The first capacitor is charged by power supplied from a second power supply unit that supplies power to a second load that is different from the first load. The first switch is arranged between the decoupling capacitor and ground. The discharge control circuit discharges, in a case where power supplied from the second power supply unit to the second load is cut off, charges of the decoupling capacitor to the ground by driving the first switch using charges stored in the first capacitor. |

1. A discharge circuit for a decoupling capacitor to stabilize a voltage supplied from a first power supply unit to a first load, the discharge circuit comprising:
a first capacitor configured to be charged by power supplied from a second power supply unit that supplies power to a second load that is different from the first load; a first switch configured to be arranged between the decoupling capacitor and ground; and a discharge control circuit configured to discharge, in a case where power supplied from the second power supply unit to the second load is cut off, charges of the decoupling capacitor to the ground by driving the first switch using charges stored in the first capacitor. |
