A Tel: (408) 260-3400 FAX: (408) 248-3416 GENERAL DESCRIPTION The CMI8800 is a spindle motor controller/ driver IC designed for DVD/CD-ROM and Video CD (VCD) applications.
This chip can be used to control/drive single phase spindle motors (see Page 20, Figure 17 for the CMI8800 Application example) as well as conventional three phase spindle motors.
It contains all of the necessary functional blocks such as the hall bias generator, hall amplifier, current limit amplifier, thermal shutdown, antireverse protection, short brake, H-bridge power driver and other functional blocks required for motor controller/driver ICs (see Page 4, Figure 2 for the CMI8800 Simplified Block Diagram).
