Description and Introduction

Unipolar Fixed-Current Chopper (Self-Excited PWM) Scheme and Built-in Phase Signal Distribution IC Two-Phase Stepping Motor Drive (Square Wave Drive) Output Current: 2.4 A The STK672-120 is a hybrid IC (thick film hybrid IC) manufactured by SANYO. It is designed as a stepping motor driver, integrating a built-in microstep controller.  

### **Specifications:**  
- **Supply Voltage (VCC):** +5V (for logic)  
- **Motor Supply Voltage (VM):** Up to +40V  
- **Output Current (IOUT):** 3.5A (peak)  
- **Microstep Resolution:** 1/16 step  
- **Package:** 25-pin SIP (Single In-line Package)  
- **Built-in Protection Circuits:** Thermal shutdown, overcurrent protection  

### **Descriptions and Features:**  
- The STK672-120 provides a compact, high-performance solution for driving 2-phase bipolar stepping motors.  
- It includes a built-in microstep controller, simplifying motor control by accepting clock and direction signals.  
- The IC supports PWM constant-current control for smooth motor operation.  
- Suitable for applications requiring precise positioning, such as printers, CNC machines, and robotics.  
- The thick film hybrid construction ensures reliability and heat dissipation.
