ABSTRACT:
An airbag device includes an airbag control IC constructed with a control signal generating circuit, a high-side switching element and a low-side switching element. Based on a signal for controlling the low-side switching element, on a signal for controlling a safety switching element and on a check mode signal, the control signal generating circuit adjusts the timing of the signal for controlling the high-side switching element so that the high-side switching element is turned on last. Therefore, the high-side switching element is turned on last. This suppresses the occurrence of an overshoot current.
