DRIVING CIRCUIT FOR INDUCTIVE LOAD

Title:

DRIVING CIRCUIT FOR INDUCTIVE LOAD

Document Type and Number:

Japanese Patent JP3198624

Kind Code:

B2

Abstract:

PURPOSE: To provide the driving circuit for the inductive load which speedily stops a current flowing to the inductive load if driving pulses are ceased.
CONSTITUTION: One end of a solenoid 1 is grounded through an NPN transistor(TR) 2 and also connected to a power source reversely through a diode 3, and the other end of the solenoid 1 is connected to the power source through a PNP TR 13 and also grounded reversely through a diode 14. Further, while the driving pulses are supplied, a monostable multivibrator 20 turns on the PNP TR 13.
