Abstract
Circuitry for protecting a first electrical system when connected to a second electrical system via a bus which provides a current-carrying signal to the first electrical system and includes a reset signal which is monitored by the second electrical system. The circuitry includes a capacitor connected to the current-carrying signal of the bus. A first switch is electrically connected between a node of the capacitor and a ground point. The first switch is closed when the first electrical system is powered-up and open when the first electrical system is powered down. A second switch is electrically connected between the reset signal of the bus and the ground point. The second switch closes due to the energy accumulated by the capacitor when the first switch is open.
