µPD168002
Stepping Motor Driver
Monolithic 6-Channel H Bridge Driver Circuit
Overview
The µPD168002 is a monolithic 6-channel H bridge driver IC consisting of a CMOS controller and a MOS output stage. Because it uses a MOS process, this driver IC consumes less current and loses less voltage at the output stage than conventional driver ICs that use bipolar transistors. In addition, because the µPD168002 employs P-channel MOSFETs in its output stage, this IC is eliminated the charge pump circuit. Therefore, the current consumption during circuit operation can be significantly reduced.
The µPD168002 is housed in a 48-pin TQFP to decrease the mounting area and height. The µPD168002 can drive one stepper motor and four DC motors and is ideal for the motor driver of CD-ROM/CD audios.
