Design of Three-Phase CDROM Motor Driver Chip by Using a 0.6um CMOS Process

摘要

This paper deals with the design and analysis of a three-phase CDROM motor driver chip using a 0.6um CMOS process.An analysis of this circuits system,it is found that the driving current can be up to 500mA as in the three-phase DC motor operation.In the CMOS process,a lot of component,i.e.,control and power circuits are integrated in the same chip.Here,we will focus on the design of high-current driver part and present the results obtained from the motor operating at different situations.
