Open loop stepper

Our integrated circuits and reference designs help you create compact, robust and efficient open loop steppers with accurate high-resolution, micro-stepping and smooth torque profile. Integrated microstep indexer and current control with smart tuning accelerate time to market.

Design requirements

Open loop stepper drive systems often require:

• Efficient small form-factor hardware protected power stage with fault feedback.
• Integrated microstepping indexer with stall detection.
• Flexible decay modes for smooth torque and high resolution microstepping.
• Input protection against reverse polarity and overcurrent.
