The µPD16835A is a monolithic quad H bridge driver IC that employs a CMOS control circuit and a MOS FEToutput circuit. Because it uses MOS FETs in its output stage, this driver IC onsumes less power than conventionaldriver ICs that use bipolar transistors.Because the µPD16835A controls a motor by inputting serial data, its package has been shrunk and the numberof pins reduced. As a result, the performance of the application set can be improved and the size of the set has beenreduced.The µPD16835A employs a current-controlled 64-step micro step driving method that drives stepper motor withlow vibration.The µPD16835A is housed in a 38-pin plastic shrink SOP to contribute to the miniaturization of the application set.The µPD16835A can simultaneously drive two stepper motors and is ideal for the mechanisms of camcorders.
