摘要： VCONN pull-down circuits and related methods are disclosed for USB Type-C connections. A device is connected through a USB Type-C connection to a separate device using connections including a CC (configuration channel) pin and a VCONN (connection power) pin. The device pulls down the VCONN pin to ground through a resistance (Ra) by applying the voltage on the CC pin to close a switch coupled between the VCONN pin and ground. The device can also be operated in a dead-battery mode where no supply voltage is present for the device. The device can also stop the pull-down on the VCONN pin after a connection is established, for example, using additional switches coupled to a pull-down control signal to remove the CC voltage and open the switch. The voltage on the CC pin can also be clamped to a desired voltage or voltage range using a voltage clamp.

摘要： An integrated circuit may include a first logic region having a first bidirectional driver circuit and a second logic region having a logic circuit and a second bidirectional circuit. The first bidirectional driver circuit may be coupled to the second bidirectional driver circuit via a conductive path. The second bidirectional circuit may receive a dynamic control signal from the logic circuit to selectively transmit a signal to the first bidirectional driver circuit based on the dynamic control signal. The first logic region further includes an additional logic circuit. The additional logic circuit may provide an additional dynamic control signal to the first bidirectional driver circuit to selectively transmit an additional signal to the second bidirectional driver circuit over the conductive path. To prevent current contention, only one bidirectional driver circuit may be activated to drive the conductive path at a given time.
