In court documents, she alleges Sheen attacked her and was caught on an audio recording threatening her life, reported People magazine.
The order says, "Mr Sheen choked Ms Ross to the point of almost losing consciousness," and that at one point he "repeatedly kicked Ms Ross while she was on the ground.
The restraining order also claims that Sheen allegedly said on the recording, "I'd rather spend USD 20,000 to have her head kicked in. Then people will realize, oh, it's dangerous."
Ross filed a lawsuit against Sheen last year, alleging in court documents that the actor kept his HIV-positive status from her during their relationship.
Ross, 26, and Sheen, 50, were engaged from November 2013 to October 2014.
