Abstract

PURPOSE:To prevent the wrong action of an injector even if the voltage of a battery falls, by providing a fuel injector controller with a built-in comparator which compares the battery voltage with a reference voltage to send out an injector action stop signal. CONSTITUTION:The voltage 301 of a battery 10 and the power voltage 302 of a regulator 11 are divided and then applied to a comparator 32, the output signal 303 of which is applied to an AND gate 33 to which the injector control signal 304 of an electronic circuit 12 including a central processing unit is also applied. An injector drive signal 305 sent out from the AND gate 33 is supplied to an injector and injector drive circuit 34. When a divided part VB of the battery voltage 301 has become not higher than a reference voltage V'th, the signal 303 falls to a low level to close the AND gate 33. For that reason, whatever the output signal 304 becomes due to the malfunctioning of the central processing unit, the injector drive signal 305 is kept at a low level not to put the circuit 34 into operation.
