UTC A9849
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.
APPLICATION
*
CD-ROM, CD-R, CD-RW, DVD-ROM, and
DVD-RAM
