Abstract
An electrical and electronic system includes an air-bag ECU and a squib. The air-bag ECU has a power supply circuit, an electronic element, a noise protection line, a switching element and a voltage detector. The noise protection line is connected between an element line, which is connected to the electronic element and the squib and to the ground. The switching element is connected to the noise protection line in series. When the voltage detector detects a large noise, it turns on the switching element to protect the electronic element from such a large noise.
