com UTC A9849 LINEAR INTEGRATED CIRCUIT 3-phase motor driver for CD-ROMs DESCRIPTION The UTC A9849 is ICs developed for CD-ROM spindle motor drives.
These ICs possess a short brake and reverserotation brake for two types of brake functions, and also contain FG output and rotation direction detection (FR) circuits,making them high-functionality and high-performance ICs.
FEATURES * Three-phase, full-wave, pseudo-linear drive system.
* Built-in power save and thermal shutdown functions.
* Built-in current limiter and Hall bias circuits.
* Built-in FG output.
* Built-in rotation direction detector.
* Built-in reverse rotation prevention circuit.
* Built-in short brake pin.
