<p>PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of minimizing the possibility for a control circuit to repeat reset/restoration processing in a cranking period.SOLUTION: A stop control circuit 30 controls an enable terminal en of a boost control IC 20 of a voltage control circuit 10 to be at a "L" level when a reset signal is given to a control circuit 17 by a reset circuit 15, to control the boost control function of the voltage control circuit 10 to be stopped. A voltage conversion circuit 11 responds to a voltage Voutputted by the voltage control circuit 10 to convert it into a voltage V, and so the voltage conversion circuit 11 can hold the output voltage Vreduced. This actualizes stable power supply of the voltage Vheld reduced to the control circuit 17 to hold the control circuit 17 in a reset state.</p> |
