UPD16856 Datasheet MONOLITHIC CD-ROM 3-PHASE SPINDLE MOTOR DRIVER

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD16856 MONOLITHIC CD-ROM 3-PHASE SPINDLE MOTOR DRIVER The µPD16856 is a CD-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 MOS FETs at the output stage, it has been possible to reduce the power consumption of the µPD16856 ever further than the conventional linear drive drivers that use bipolar transistors. By using a 30-pin shrink SOP package, a more compact-size has been achieved.
