We present the measurements of mixing-induced CP asymmetry in semileptonic B-meson decays using the full data set collected at the peak of the Y(4S), with the BABAR detector at SLAC. The lepton charge directly identifies the B meson flavor in decays; charged kaon is also used in tagging B meson flavor. Asymmetry between B meson pairs decay as B0-B0 and B0bar-B0bar indicates CP violation in mixing.
