DESCRIPTION
The µPD16835A is a monolithic quad H bridge driver IC that employs a CMOS control circuit and a MOS FET output circuit. Becau it us MOS FETs in its output stage, this driver IC consumes less power than conventional driver ICs that u bipolar transistors.
Becau the µPD16835A controls a motor by inputting rial data, its package has been shrunk and the number of pins reduced. As a result, the performance of the application t can be improved and the size of the t has been reduced.
The µPD16835A employs a current-controlled 64-step micro step driving method that drives stepper motor with low vibration.
撩人土味情话The µPD16835A is houd in a 38-pin plastic shrink SOP to contribute to the miniaturization of the application t.The µPD16835A can simultaneously drive two stepper motors and is ideal for the mechanisms of camcorders.
FEATURES
•Four H bridge circuits employing power MOS FETs •Current-controlled 64-step micro step driving
•Motor control by rial data (8 bytes x 8 bits) (original oscillation: 4-MHz input)Data is input with the
LSB first.
