A Universal Serial Bus (USB) Type-C connector subsystem is described herein. An integrated circuit (IC) chip device includes a Universal Serial Bus (USB) Type-C subsystem. The USB Type-C subsystem is to operate an Ra termination circuit that consumes no more than a first predetermined amount of current after the Ra termination circuit is applied to a Vconn line of the Type-C subsystem, or to operate a standby reference circuit in a low power mode of the device to perform detection on a Configuration Channel (CC) line of the Type-C subsystem, where the device consumes no more than a second predetermined amount of current in the low power mode.

Type-C connector subsystem

Techniques for low-power implementation of a Universal Serial Bus (USB) Type-C connector subsystem are described herein. In an example embodiment, an integrated circuit (IC) chip device comprises a Universal Serial Bus (USB) Type-C subsystem. The Type-C subsystem is configured to operate an Ra termination circuit that consumes no more than 100 &#x3bc;A of current after the Ra termination circuit is applied to a Vconn line of the Type-C subsystem, and/or to operate one or more standby reference circuits in a deep-sleep state of the device to perform detection on a Configuration Channel (CC) line of the Type-C subsystem, where the device consumes no more than 100 &#x3bc;A of current in the deep-sleep state.
