DATA SHEET MOS INTEGRATED CIRCUIT µPD16835 MONOLITHIC QUAD H BRIDGE DRIVER CIRCUIT The µPD16835 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 µPD16835 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. This IC employs a current-controlled 64-step micro step driving method that drives stepper motor with low vibration.
