Features

・The spindle motor driver achieves a low noise by S!PWM^×2 super low noise drive method of an original Rohm.
・The spindle motor driver built the gain switch function in, and it enabled the low-speed stability rotation.
・Actuator coil driver is no dead zone system and linearity is good.
・Actuator coil driver can be optimized the frequency characteristic matched to the load characteristic by external R.C.
・When the tilt coil load is not used by the set, it is possible to use it as an eject motor driver.
・STBY input is three state input, and only the spindle motor drive can be operated.
