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.

The

µPD16835 is housed in a 38-pin shrink SOP to contribute to the miniaturization of the application set.

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