Document Type and Number:
WIPO Patent Application WO/2010/090334
Kind Code:
A1
Abstract:
An electronic circuit is provided with: a first power supply line which can supply power; a second power supply line which can supply power independently from the first power supply line; a main circuit connected to the second power supply line; a detecting section which detects that power is supplied from either the first power supply line or the second power supply line; and a control section connected to the first power supply line and the second power supply line.  When the detecting section detects that power is supplied from the first power supply line, the control section controls the voltage/current to be supplied from the first power supply line and supplies power to the main circuit.
