3-Phase Motor Driver For CD-ROM/R-RW,DVD-ROM/RAM
BA6668FM
Description
Dim ension (Uni ts:mm)
The BA6668FM is a motor driver developed for
CD-R RW spindle motors. This IC has a junction temperature
alarm pin, a gain switch and a limit switch
pin. A power save, thermal shut down, current limit,
rotation detector, and a reverse protection circuit are
all included. Gain and Limit can be switched by the
control pin.
Features
1)3-phase, full-wave pseudo linear driving system
2)Built-in power save, thermal shut down circuit
3)Built-in current limit, Hall Bias circuit
4)Built-in FG-output, FG3-phase synthesized output
5)Built-in rotation detector
6)Built-in reverse protection circuit
7)Built-in Limit switch and Gain switch pin
8)Built-in Short Brake pin
9)Built-in junction temperature alarm pin
10)Suitable for 3.3V DSP
