3-phase Motor Driver for DVD-ROM Spindle Motors
BD6663FM
Description 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 output 5) Built-in Hall bias 6) Built-in reverse protection circuit 7) Low power consumption by MOSFET 8) Built-in short brake SW pin 9) Built-in rotation direction detect terminal
