What is a Stepper Motor Driver?
Stepper motor also called stepping motor, is a type of DC Motor that rotates in fixed angular steps when the sequence of electric pulses is applied to it. Stepper motor drivers are used to drive the voltage and current of stepper motor stator windings as per the sequence. It consists of a gate driver and power driver circuits to drive the motor windings, control logic circuits, PWM generating circuits, serial interface circuits, and has protection features such as under-voltage Lockout (UVLO) protection, over-voltage protection, short circuit protection, over current protection, and thermal protection.
Key features of Stepper Motor Drivers:
- Multiple decay modes (mixed, slow & fast).
- Built-in micro-stepping indexer.
- Support half-step, full-step, and micro-stepping mode.
- Low current sleep mode.
- Programmable maximum winding current.
- Programmable motion control.
- Overcurrent Protection (OCP).
- Hot thermal warning and thermal shutdown (TSD).
- Overvoltage and under-voltage lockout (UVLO) protection.
- Fault condition indication pin.
- Short circuit protection.
- Support direct and I2C/SPI interface.
Stepper motor drivers are ideal for use in money handling machines, video security cameras, printers, scanners, office automation machines, gaming machines, factory automation, robotics, refrigerator damper, ice maker, washers, dryers, dishwashers, electronic point-of-sale (ePOS) printers, stage lighting equipment, miniature circuit breakers, smart meter, ATM, textile machines, office, home, factory automation, unipolar stepper motors, automotive stepper motors, engine management, headlamp positioning HVAC flap, and valve control applications.
