The PD16835 is a monolithic quad H bridge driver IC that employs a CMOS control circuit and a MOS FET output circuit. Because it uses MOS FETs in its output stage, this driver IC consumes less power than conventional driver ICs that use bipolar transistors. Because the PD16835 controls a motor by inputting serial data, its package has been shrunk and the number of pins reduced. As a result, the performance of the application set can be improved and the size of the set has been reduced.
