Abstract
The present invention is aimed at avoiding noise generation accompanying switching actions in booster circuits for a load such as an air-bag driving circuit. In an air-bag driving circuit, which is designed to actuate an igniting transistor 13 in response to output of a collision detecting signal from a collision detector 7 for detecting a collision condition of a vehicle so as to supply an igniting current to a squib 11 based on a voltage boosted by booster circuits 4 and 5, the boosting operation of the booster circuits 4 and 5 is inhibited while the collision detecting signal is absent and started when the collision detecting signal is output from the collision detector 7.
