SA5664
3-PHASE SPINDLE MOTOR DRIVER FOR CD-ROM
DESCRIPTION
The SA5664 is a CD-ROM spindle motor driver supporting reverse-
rotation preventing circuit. It incorporates power save circuit, thermal shut
down circuit, FG output, hall bias, etc. The 3-phase full-wave pseudo linear
driving system achieves high-performance and multi-function.
FEATURES
* 3 -phase, full-wave, pseudo linear driving system.
* Built-in power save in stop mode.
* Built-in current limiter.
* Built-in 3X and 1X hall FG output.
* Built-in TSD (thermal shutdown) circuit.
* Built-in gain switch pin.
* Built-in hall bias circuit.
* Built-in rotational direction detector.
* Built-in short-brake.
* Built-in reverse rotation prevented circuit.
* Built-in brake mode pin.
* Corresponds to 3.3V DSP.
