Overview
PCA9629 Fm+ I2C-bus stepper motor controller Rev.
1 — 29 February 2012 Product data sheet 1.
General description 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-phase (wave drive), two-phase, and half-step.
In addition, when used as inputs, four General Purpose Input/Outputs (GPIOs) allow sensing of logic level output from optical interrupter modules and generate active LOW interrupt signal on the INT pin of PCA9629.
This is a useful feature in s...
