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.
