  • MAIN BOARD, HOT PLUG CONTROL SIGNAL GENERATOR, AND CONTROL SIGNAL GENERATING METHOD THEREOF
    Publication number: 20240322827
    Abstract: A main board, a hot plug control signal generator, and a control signal generating method thereof are provided. The hot plug control signal generator includes a controller and a latch. The controller provides a control signal. The latch is operated based on an operation power to generate a hot plug control signal. The latch sets the hot plug control signal to a disabled first logic value, and latches the hot plug control signal at the first logic value.

  • Electronic device for hot plugging detection
    Patent number: 11334517
    Abstract: An electronic device is provided. The electronic device includes a board, a first latch mechanism, and an expansion card. A controller is disposed on the board. The first latch mechanism is disposed on the board. The first latch mechanism is electrically connected to the controller. The expansion card is plugged in the first latch mechanism and disposed over the board. The expansion card is electrically connected to the controller through the first latch mechanism. The controller determines a connecting condition of the first latch mechanism according to a connecting signal provided by the expansion card.
