AMC5902
6CH Motor Driver for
CD-ROM, DVD-ROM
DESCRIPTION
The AMC5902 is a monolithic chip with 6 channel motor
drivers designed by advanced BiCMOS process technology.
The AMC5902 contains 3 BTL drivers,2 PWM drivers and a
3-phase spindle motor driver.
The AMC5902 is the best fit for modern optical disk driver
system which has spindle motor and all actuators.
The AMC5902 contains a direct PWM control system for
spindle and two slide channels drive thus that the total power
consumption can be reduced. Besides, voltage supplies for
spindle, slide, focus/tracking and loading can be set separately.
Further more, the two control modes -ON/OFF of loading,
FOUT amplifier, brake mode select of spindle driver, standy
mode, thermal shut down circuit are internally designed in.
These features make the AMC5902 an ideal device for optical
disc related systems.
FEATURES
Designed by advanced BiCMOS process, low
power and low chip temperature.
Patented package to reduce chip temperature.
3 BTL drivers, 2 PWM drivers and 3 phase
spindle motor driver.
Built-in triangular-wave generator.
0 to 5V wide voltage range for input pins
Thermal shutdown with 30°C hysteresis.
Built-in current limit, hall bias,short brake,
FOUT output and reverse protection circuit.
APPLICATIONS
CD-RW, DVD-RW
CD-ROM, DVD, DVD-ROM
