3-Phase Brushless Motor Driver
REJ03F0081-0100Z
Rev.1.0
Sep.22.2003
Description
The M56733AFP is a semiconductor integrated circuit designed as a single-chip controller for FDD spindle motors. It
incorporates a power amplifier, Hall amplifier, FG amplifier, oscillator, and speed discriminator, along with various
protective circuits. Control of switching between three speeds by the single MOD pin gives this IC the edge for use in
compact systems.
Features
Digital servo provides high precision, good stability, and freedom from the need for adjustment.
A single pin controls switching between three speed.
