Title:
電力供給制御回路
Document Type and Number:
Japanese Patent JP5274824
Kind Code:
B2
Abstract:
An exemplary aspect of a power supply control circuit includes a reference voltage control circuit (131) that applies a potential corresponding to a potential of a second power supply line (103) to a reference voltage node (130) connected to a control terminal of a first switch (110) when a power supply voltage is applied in a forward direction between first and second power supply lines (101,103), and that applies a potential corresponding to a potential of a first power supply line (101) to the reference voltage node (130) when the power supply voltage is applied in the reverse direction between the first and second power supply lines (101,103).
