BD6663FM - ETC

BD6663FM 3-Phase Motor Dricer for DVD-ROM Spindle Motors

The BD6663FM is a motor driver developed for high-speed CD-ROM and DVD-ROM applications that requires low power consumption and low heating. This is accomplished by applying PMOS Tr/DMOS Tr to Tr output and PWM operation. Dimension (Units : mm) Features 1) Direct PWM driver 2) Built-in power saving circuit 3) Built-in current limit circuit 4) Built-in FG o.
