Abstract
In an activating device for a passenger protection system in a vehicle, erroneous activating operation caused by improper operation of a microcomputer or electrical noise is prevented even though electronic switches are used to operate a squib. A microcomputer has output ports connected to first through third driving circuits controlling first through third electronic switching devices connected in series with a squib for deploying a passenger protection device. A timer circuit is connected to the first switching device by way of a prohibiting circuit provided as a hardware unit independent of the microcomputer.
