PD16882
MONOLITHIC CD-ROM/DVD-ROM 3-PHASE SPINDLE MOTOR DRIVER
DESCRIPTION
The
碌
PD16882 is a CD-ROM/DVD-ROM 3-phase spindle motor driver consisting of a CMOS controller and MOS
bridge outputs.
By employing 3-phase full-wave PWM as the drive method and MOSFETs at the output stage, it has been
possible to reduce the power consumption of the
碌
PD16882 ever further than the drivers that use bipolar transistors.
By using a 30-pin shrink SOP package, a more compact-size has been achieved.
