Motor driver ICs

FDD spindle motor driver

BA6492BFS

The BA6492BFS 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, two monostable multivi-

brator elements, and a power save circuit. The compactly packaged IC reduces the number of external components

required.
