GENERAL DESCRIPTION The 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). FEATURES Brushless DC motor controller/driver IC dedicated for DVD/CD-ROM and Video-CD (VCD) spindle motor applications Can drive both single phase spindle motors as well as conventional three phase spindle motors Built-in hall bias generator and hall amplifiers for easy interface with hall sensor devices Built-in sleep or start/stop mode to put the chip and motor into sleep mode for power saving

Built-in current limit amplifier to limit the maximum allowed current into the motor coil Built-in thermal shutdown for overheat protection Built-in torque control to setup the motor's torque according to the control voltage applied to the EC and ECR pins Built-in anti-reverse protection circuitry to prevent the motor from going into the opposite (reverse) rotation direction in the constant linear velocity (CLV) operating mode (used when the rotation speed is decreased from the inner track to the outer track) Built-in frequency generator (FG) output as well as rotation detect (FR) output circuitry Built-in short brake circuitry to short all of the motor coils and stop the motor quickly Compatible with 3.3V digital signal processor (DSP) interface
