Description and Introduction

4-Phase Stepping Motor Driver Unipolar Self-Excitation Type(Io = 1.5A) The STK6711AMK4 is a hybrid IC (integrated circuit) manufactured by Sanyo (now part of ON Semiconductor). It is designed for use in motor control applications, particularly for driving stepping motors.  

### **Specifications:**  
- **Type:** Unipolar Stepping Motor Driver IC  
- **Output Current:** 1.5 A (max)  
- **Supply Voltage (VCC):** 12 V to 40 V  
- **Logic Supply Voltage (VDD):** 4.5 V to 5.5 V  
- **Number of Phases:** 4-phase  
- **Package:** SIP (Single In-line Package)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
- The STK6711AMK4 is a compact, high-performance hybrid IC designed for driving unipolar stepping motors.  
- It integrates power MOSFETs and control circuitry in a single package.  
- It supports full-step, half-step, and microstepping modes for precise motor control.  

### **Features:**  
- Built-in current limiting and thermal protection.  
- Low power consumption in standby mode.  
- Compatible with 5 V logic levels for easy interfacing with microcontrollers.  
- High efficiency and low heat generation due to MOSFET output stage.  

The STK6711AMK4 is commonly used in industrial automation, robotics, and precision positioning systems.

Application Scenarios & Design Considerations

4-Phase Stepping Motor Driver Unipolar Self-Excitation Type(Io = 1.5A)

Alternative Part Number

  • STK672-440A --: Same STK motor driver family with integrated controller and power stage, widely used as a direct functional replacement for STK6711 series stepper drivers.
  • TB6600HG --: Bipolar stepper motor driver IC with comparable current and voltage ratings, commonly used to replace STK6711AMK4 in stepper drive designs.
  • L298N --: Dual H-bridge driver capable of driving stepper motors at similar power levels, a common generic substitute when the original STK module is unavailable.
  • STK6712AMK4 --: Same STK671x series stepper motor driver from the original Sanyo line, higher current rating and pin-compatible, making it a direct drop-in upgrade.
  • STK6713AMK4 --: Sister part in the same driver family with similar package and control interface, suitable when slightly higher output capability is acceptable.
