Abstract
A power management scheme for USB systems. For Mobile systems that has re-timer, a handshake is used between power delivery (PD) controller, re-timer and embedded controller (EC) so that the PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition allowing Dynamic Platform and Thermal Framework (DPTF) framework to boost CPU performance and enhance battery capacity respectively. The same solution can be extended to desktop segment to allow PD controller to lower the USB-C power contract with connected devices before switching to standby rail. For mobile systems that are without re-timer, a handshake is used between BIOS, PD controller and EC so that PD controller can end higher wattage power contract on USB-C connector after TBT/USB4 link is in low power (CLd/U3) and during system low power transition.
