Description
Suitable for a 3-phase BLDC (Brush-Less Direct Current) spindle
motor driver with PWM, the monolithic FAN8741/FAN8742 IC also
includes 2-ch motor drivers with PWM for sled motors and 4-ch
linear drivers which drive the focus actuator, tracking actuator, tilt
actuator, and loading motor in optical media applications.
Designed specifically for high-speed/high-density optical media
applications, the FAN8741/FAN8742’s power stage is created by
D-MOS transistors which have extremely low RDS
ON
. This
enables less heat generation and guarantees improved reliability.
The
FAN8741G/FAN8742G is available in a 56-SSOP-HS pack-
age, which has high-power dissipation and the leadframe is
exposed to the top side.
The FAN8741MTF/FAN8742MTF is available in a 56-TSSOP-EP
package, which is very thin and the leadframe is exposed to
the bottom side.
