DESCRIPTION

The μPD168102 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, the μPD168102 employs P-channel MOSFETs in its output stage, eliminating the need for an on-chip the charge pump circuit. Therefore, the current consumption during circuit operation can be significantly reduced.
