Abstract: A system configured to protect a load within a vehicle includes a plug subassembly and a sensor connector subassembly. The sensor connector subassembly is selectively connectable to the plug subassembly. A circuit board is secured within the sensor connector subassembly. The circuit board includes at least one positive temperature coefficient (PTC) device electrically connected between an activation switch and a load. The circuit board includes at least one circuit to protect against over-voltage or over-current to the load, detect a fault condition of the load, and determine whether the plug subassembly is connected to the sensor connector subassembly.

Abstract: A solid state pre-charge module includes a relay, a transistor connected to the relay and a solid state device connected to the transistor. The solid state device controls switching of the transistor.

Abstract: A driver module is provided for controlling operation of a fuel pump of a vehicle. The driver module includes switching circuitry for switching transmission of electrical power to the fuel pump, and a processor for executing a series of programmable instructions for controlling the switching circuitry in accordance with at least one signal received from a restraint control module (RCM) of the vehicle.

Abstract: An arc protection relay, particularly suited for use in 42 volt automotive systems applications has input terminals for connection to an external power source; output terminals for connection to an inductive load; a contact connected in series to the input terminal and the output terminal; a relay coil connected to the input terminals and operatively connected to the contact; and at least one energy absorbing device, such as a metal-oxide varistor or a transient surge suppressor, connected in parallel with the output terminals for absorbing fluctuating reverse voltage from the output terminals and optionally contains a second energy absorbing device in the form of a coil suppressor for protecting the coil from voltage surges and a magnet operatively positioned to blow an arc from the contact.
