PCA9629 Fm+ I2C-bus stepper motor controller

The PCA9629 is an I2C-bus controlled low-power CMOS device that provides all the logic and control required to drive a four phase stepper motor. PCA9629 is intended to be used with external high current drivers to drive the motor coils. The PCA9629 supports three stepper motor drive formats: one-pha.

PCA9629 Features

* Generate motor coil drive phase sequence signals with four outputs for use with external high current drivers to off-load CPU

* Four balanced push-pull type outputs capable of sinking 25 mA or sourcing 25 mA for glueless connection to external high current drivers needed to drive motor coi
