3-phase motor driver for CD-ROMs
BD6660FV
The BD6660FV is low power consumption CD-ROM spindle driver that uses MOS transistor in the output. To meet the requirements for notebook computers, the thin power package SSOP-B28 is used and a PWM drive with a MOS processor output stage achieves an extremely low power consumption. FApplications Portable CD-ROMs, DVDs FFeatures 1) Direct PWM drive. 2) Built-in power save circuit. 3) Built-in current limiter circuit. 4) Built-in FG output. 5) Built-in Hall biasing. FAbsolute maximum ratings (Ta = 25_C)
