UPD16879 Overview
DATA SHEET MOS INTEGRATED CIRCUIT µPD16879 MONOLITHIC QUAD H BRIDGE DRIVER CIRCUIT The µPD16879 is a monolithic quad H bridge driver IC that employs a CMOS control circuit and a MOSFET output circuit. Because it uses MOSFETs in its output stage, this driver IC consumes less power than conventional driver ICs that use bipolar transistors. Because the µPD16879 controls a motor by inputting serial data, its package has...
