The voltage regulator may regulate the input voltage to be the minimum firing voltage at the input terminal. The squib driver circuit may be formed on a single chip. The squib driver circuit may include a high side driver and a low side driver. An input terminal for receiving an input voltage used to fire the deployable restraint. The high side driver may supply current from the input terminal to the deployable restraint. The low side driver may supply current from deployable restraint to the electrical ground.

Abstract: A method and system for diagnosing a fault condition in common connected squib loops is disclosed. A current source supplies current to the feed terminal for the first squib loop and current is returned through the feed terminal for the second squib loop. The voltage is measured between the feed terminal for the first squib loop and the feed terminal for the second squib loop.

Abstract: A duplex firing initiator for an airbag inflator includes both a primary initiator and a secondary initiator for electrical connection to a Restraint Control Module. In the duplex firing initiator, current is conducted in a forward polarity through the primary initiator to actuate the primary initiator and current is conducted in a reverse polarity through the secondary initiator to actuate at least the secondary initiator.

Abstract: A squib driver circuit for deployment of an active safety restraint in a vehicle. The squib driver circuit may include a high side protection circuit. The high side protection circuit may include a comparator circuit to compare the input voltage to a reference voltage and activate a timer in response to the input voltage exceeding the reference voltage, the timer generating a disable signal to disable the high side driver after a predetermined period of time The high side protection circuit may disable the high side driver after a short is detected and elapse of the predetermined period of time. The squib driver circuit may be formed on a single chip.

Abstract: A method and system for diagnosing the squib leakage resistance through a restraint control module is disclosed in the present application. The newly proposed system and method provides a highly accurate measurement by minimizing/eliminating the effect of the unknown source voltage effects. The concept utilizes the squib leakage resistance diagnostic resources with a multi-step measurement approach, for example utilizing measurements of two currents and/or two voltages.

Abstract: A method of measuring squib loop resistance including non-linear elements in a restraint control module is disclosed by the present invention. The squib loop resistance is comprised of both linear and non-linear elements. The non-linear elements are linearized into resistive components about the bias points used to make the squib loop resistance measurement. The calculation of the linear squib loop resistance is provided by comparing the complete squib loop resistance and the linearized value of the non-linear elements.

Abstract: A method and system for diagnosing a squib loop in a restraint control module using a transient response is disclosed in the present application. The system may be used with a low energy actuator (LEA) which is primarily an inductive device. A diagnostic current may be applied to the squib loop for a diagnostic test period and the voltage between the feed line terminal and the return line terminal or the voltage between the return line terminal and the feed line terminal can be monitored at a specific time or times during the test period for the expected response (e.g. peak voltage, rise rate, etc). The current may also be reversed to check the correct polarity of a diode in the LEA.
