Abstract
A power saving apparatus and method for a host system to proactively decide to save power and increase battery life when bus powered peripheral devices are connected to the System's USB TYPE-C ports. The Host (or Host System) decides if a Bus Powered Device (BPD), hub or a peripheral device requires application services, or a device-initiated wake based on wake policies of a respective Universal Serial Bus (USB) 3.2, THUNDERBOLT 3 (TBT3), USB4, DISPLAYPORT (DP) Protocol. Thereafter, the Host decides based on S0, Low Power System standby entry—wake time latency requirement along with USB TYPE-C IO Protocol policies, to trigger the system power delivery (PD) Controller to remove power to the BPD. To save power, the Host System Wake logic power partition is also powered off.
