FDD spindle motor driver
BA6477FS
The BA6477FS is a one-chip IC designed for driving FDD spindle motors. This high-performance IC employs a 3-phase,
full-wave soft switching drive system, and contains a digital servo, an index amplifier, and a power save circuit. The com-
pactly packaged IC reduces the number of external components required.
Applications
Floppy disk drivers
Features
1) 3-phase, full-wave soft switching drive system.
2) Digital servo circuit.
3) Power save circuit.
4) Hall power supply switch.
5) Motor speed changeable.
6) Index amplifier.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions (Ta = 25 C)
