The
μ
PD16879 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
μ
PD16879 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
μ
PD16879 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.
