µ PD16835

MONOLITHIC QUAD H BRIDGE DRIVER CIRCUIT

DESCRIPTION

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.

The µPD16835 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 plastic shrink SOP to contribute to the miniaturization of the application set.

The µPD16835 can simultaneously drive two stepper motors and is ideal for the mechanisms of camcorders.
