US Patent 10929320 Control circuit for dynamic bifurcation control

A system and method for generating a control bifurcation signal in accordance with the Open Compute Project (OCP) Specification. An OCP device is provided that has a bifurcation function with an input to activate a bus bifurcation function. An input/output control circuit having an output coupled to a bifurcation control line coupled to the OCP device is provided. The input/output control circuit is operable to provide a bifurcation control signal to the OCP device over the bifurcation control line during an auxiliary power phase transition period of powering-on the OCP device.
