Title:
POWER FEEDING CIRCUIT
Document Type and Number:
Japanese Patent JP2011194902
Kind Code:
A
Abstract:

To provide a power feeding circuit that reduces power consumption in a sleep mode.

A controller 43 turns on a semiconductor switch 41 in a normal mode, and turns off the semiconductor switch 41 in the sleep mode. A bypass resistor 5 is connected in parallel to the semiconductor switch 41. A resistance value of the bypass resister 5 is so large as that in the sleep mode, a dark current is supplied to an electronic device 3 via the bypass resistor 5, and if an electric wire downstream of the bypass resistor 5 is short-circuited, an electric current more than a permissive current is prevented from flowing to the electric wire.
