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 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.

The

µPD16879 is a housed in a 38-pin shrink SOP to contribute to the miniaturization of application set.

This IC can simultaneously drive two stepper motors and is ideal for the mechanisms of camcorders.
