摘要： A gate drive circuit includes a first gate terminal, a second gate terminal, and a driver circuit including an input and including an output coupled to the first gate terminal. The driver circuit is configured to provide a drive signal to the first gate terminal to control a first switch to selectively couple a first current path to a first wire pair of a network port. The gate drive circuit further includes a switch including a first terminal coupled to the output of the driver circuit, a second terminal coupled to the second gate terminal, and a control terminal responsive to a switch control signal to selectively couple the output of the driver circuit to the second gate terminal to control a second switch to selectively couple a second current path to a second wire pair of the network port.

摘要： An apparatus (10) includes a housing (70) defining a chamber (80). The housing (70) also defines a vent passage (86) communicating the chamber (80) with the atmosphere outside the housing. A gas generator (120) associated with the housing (70), when actuated, generates gas in the chamber (80). A pressure relief plug (140) blocks gas flow through the vent passage (86) when the pressure relief plug is at a first temperature. The pressure relief plug (140) is made of a material which melts at a second temperature above the first temperature causing the vent passage (86) to become unblocked. The pressure relief plug (140) is insertable into the vent passage (86) and has a snap action connection with the housing (70).
