Description and Introduction

Stepping Motor Drivers The **STK672-330** is a hybrid IC (integrated circuit) manufactured by **SANYO** (now part of ON Semiconductor).  

### **Specifications:**  
- **Type:** Stepper motor driver IC (unipolar/bipolar)  
- **Output Current:** Up to 3.0A (peak)  
- **Supply Voltage (VCC):** 12V to 40V  
- **Logic Supply Voltage (VDD):** 5V  
- **Package:** SIP (Single In-line Package)  
- **Built-in Features:**  
  - PWM current control  
  - Built-in thermal shutdown protection  
  - Built-in overcurrent protection  
  - Built-in clamp diodes for inductive load protection  
- **Control Method:** Microstepping (compatible with 1/2, 1/4, 1/8, and 1/16 step modes)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions & Features:**  
- Designed for driving **two-phase hybrid stepping motors** efficiently.  
- Supports **unipolar and bipolar** motor configurations.  
- Includes an **onboard oscillator** for microstepping control.  
- **Low heat generation** due to efficient PWM current regulation.  
- Suitable for **industrial automation, robotics, CNC machines, and precision positioning systems**.  
- **Compact SIP package** for easy integration into motor control systems.  

This IC is optimized for smooth motor operation with minimal vibration and noise.

Application Scenarios & Design Considerations

Stepping Motor Drivers

Alternative Part Number

  • TB6600HG --: Bipolar stepper motor driver IC with similar function and voltage/current capability, commonly used as a direct replacement in stepper drive designs.
  • A4988 --: Widely available microstepping stepper motor driver IC suitable for similar low-to-medium current stepper applications, easy to source and well documented.
  • DRV8825 --: Integrated stepper motor driver with comparable microstepping control and current handling, offering higher voltage margin and good availability.
  • L298N --: Widely available dual H-bridge motor driver that can drive stepper motors in the same application class, though external circuitry may be needed.
