Description
The FAN8741G/FAN8742G is a monolithic IC suitable for a
3-phase BLDC(Brush Less Direct Current) spindle motor
driver with PWM, 2-ch motor drivers with PWM for sled
motor and 4-ch linear drivers which drive the focus actuator,
tracking actuator, tilt actuator and loading motor of the opti-
cal media applications. Since FAN8741G/FAN8742G aims
to high-speed/high-density optical media applications its
power stage is made by D-MOS transistors which have
extremely low RDS on. This enables less heat generation
and guarantees more reliable lifetime.
