Motor driver ICs 3-phase motor driver for CD-ROMs BA6849FP / BA6849FP-Y / BA6849FM / BA6849FS The BA6849 series are ICs developed for CD-ROM spindle motor drives. These ICs possess a short brake and reverserotation brake for two types of brake functions, and also contain FG output and rotation direction detection (FR) circuits, making them high-functionality and high-performance ICs. FApplications CD-ROM, CD-R, CD-RW, DVD-ROM, and DVD-RAM FFeatures 1) Three-phase, full-wave, pseudo-linear drive system. 2) Built-in power save and thermal shutdown functions. 3) Built-in current limiter and Hall bias circuits. 4) Built-in FG output. FAbsolute maximum ratings (Ta = 25_C) 5) Built-in rotation direction detector. 6) Built-in reverse rotation prevention circuit. 7) Built-in short brake pin.
