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.

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 coils.
Up to 1000 pF loads with 100 ns rise and fall times.
Built-in oscillator requires no external components.
Stepper motor drive control logic.
One-phase (wave drive), two-phase,.
