Title:
POWER SOURCE DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JPS6371452
Kind Code:
A
Abstract:
PURPOSE:To seek to economize power by arranging the constitution in such a way that consumption current becomes zero at waiting and required voltage is supplied only in control operation in the power supply circuit of a control device for controlling an actuator such as room lamp, etc. which is connected to a battery without the aid of an ignition switch. CONSTITUTION:In the door closed condition (door switch 10 is OFF), that is, in the waiting condition, transistors TR1, TR2 are OFF and voltage to be applied from a stabilizing power source circuit 9 to the power source terminal of an integrated control circuit 11 is zero. Accordingly TR3 and TR4 are OFF and a room lamp 3 is in the extinguished condition. Next when the doer is opened, the door switch 10 is turned on and TR1 is turned off, so the stabilizing power source circuit 9 operates and stabilizing voltage is supplied to the integrated control circuit 11. Accordingly, H signal is output to output terminals theta1, theta2 in response to a command signal to an input terminal 1 and the room lamp 3 is lit by the ON operation of the TR3 and TR4.
