Abstract
An electronic control unit for a restraint control module comprises a PSI5 communications interface configured to communicate with a remote sensor using a current-modulated signal with PSI5 compliance upon a two-wire interconnection. The PSI5 communications interface includes a signal driver configured to apply a signal voltage to a first signal terminal for driving current to the remote sensor via the two-wire interconnection. The PSI5 communications interface also includes a second signal terminal providing a return path for the current; and a resistor within the return path of the PSI5 communications interface. Several different alternative impedance balancing and damping circuits are provided to provide the resistor. The alternative impedance balancing and damping circuits include passive and active resistors. The impedance balancing and damping circuit may also provide current protection against damage due to fault currents. A method for operating a PSI5 communications interface of a restraint control module is also provided.
