  • Electronic circuit arrangement having polarity reversal protection
    Patent number: 5764465
    Abstract: A MOS field-effect transistor (T2) is provided in conjunction with transistors (T1 and T3) as polarity reversal protection in an electrical circuit arrangement (1). Polarity reversal protection of this type is realized by the drain-source path of the transistor (T2). Transistors (T1 and T3) form a comparator. If the drain-source voltage of the transistor (T2) becomes negative then the transistor (T3) switches on. This, in turn has the effect of switching off the transistor (T2) thereby providing polarity reversal protection. The electronic circuit arrangement (1) configured according to the invention can advantageously be used in an airbag system (10).
