Description and Introduction

Stepping Motor Drivers The STK672-330 is a hybrid IC (integrated circuit) manufactured by SANYO (now part of ON Semiconductor). It is designed as a stepping motor driver with a built-in microstep controller.  

### **Specifications:**  
- **Motor Type:** 2-phase bipolar stepping motor  
- **Output Current:** 3.0 A (max)  
- **Supply Voltage (Motor):** Up to 40 V  
- **Control Method:** PWM current control  
- **Microstepping:** Supports 1/8, 1/16 microstepping  
- **Protection Features:** Overcurrent, thermal shutdown  
- **Package:** SIP (Single In-line Package)  

### **Descriptions and Features:**  
- The STK672-330 integrates a microstepping controller and power stage in a single module.  
- It allows smooth motor operation with reduced vibration and noise due to microstepping capability.  
- The built-in PWM current control ensures efficient motor driving.  
- Suitable for applications requiring precise positioning, such as printers, CNC machines, and automation systems.  
- The thermal shutdown and overcurrent protection enhance reliability.  

For exact electrical characteristics and application circuits, refer to the official datasheet from the manufacturer.
