City attorney's spokesman Frank Mateljan said Wednesday that 54-year-old Joe Simpson faces a maximum sentence of 6 months in jail, 36 months of probation and a $1,000 fine.
He was arrested Aug. 4 after authorities say he registered a blood-alcohol level of 0.08 percent or above at a DUI checkpoint in the Sherman Oaks area.
The charges were filed Tuesday. Simpson is due for arraignment Aug. 30 in a Van Nuys court.
Simpson is a former minister. He helped make stars of his two daughters by managing their singing careers.
