Description and Introduction

Unipolar Fixed-current Chopper-type 4-phase Stepping Motor Driver The STK6712AMK3 is a hybrid IC (integrated circuit) manufactured by Sanyo. It is designed as a stepping motor driver, commonly used in applications requiring precise motor control.  

### **Specifications:**  
- **Manufacturer:** Sanyo  
- **Type:** Hybrid IC (Stepping Motor Driver)  
- **Output Current:** Up to 1.5A (per phase)  
- **Supply Voltage:** 12V to 40V (recommended operating range)  
- **Control Method:** PWM (Pulse Width Modulation) current control  
- **Built-in Protection Features:** Thermal shutdown, overcurrent protection  
- **Package Type:** SIP (Single In-line Package)  

### **Descriptions and Features:**  
- The STK6712AMK3 is optimized for driving bipolar stepping motors.  
- It includes a built-in microstepping controller for smoother motor operation.  
- The IC supports full-step, half-step, and microstepping modes.  
- Low power consumption due to efficient PWM current control.  
- Suitable for applications such as printers, CNC machines, and robotics.

Alternative Part Number

  • STK672-440A --: Same STK672 stepper motor driver family with integrated controller, similar function and package style, commonly used as a direct replacement in stepper drive designs.
  • TB6600HG --: Bipolar stepper motor driver IC with comparable current and voltage ratings, widely used as a functional substitute for STK-series stepper drivers.
  • L298N --: Dual H-bridge driver capable of driving stepper motors, easy to source and often used when the original STK driver is unavailable, though external control logic may be needed.
