Abstract
Embodiments relate to fault detection comparator circuitry and methods that can operate in conjunction with a power-on-reset (POR) scheme to put a chip into a reliable power-down mode upon fault detection to avoid disrupting the communication bus link such that other connected chips and the host can continue to operate. Power-on of the affected chip can then be carried out when the connection with that chip is restored.
