Description and Introduction

N-channel P-channel 3-phase motor drive The **SLA5060** is a **stepper motor driver IC** manufactured by **Sanken Electric Co., Ltd.** (SK). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Type:** Unipolar Stepper Motor Driver IC  
- **Output Current:** 1.5A (per phase)  
- **Supply Voltage (VCC):** Up to 50V  
- **Logic Voltage (VDD):** 5V  
- **Number of Outputs:** 4 (for 2-phase stepper motor control)  
- **Package:** SIP (Single In-line Package)  
- **Built-in Protection Features:** Thermal shutdown, overcurrent protection  

### **Descriptions:**  
- Designed for **unipolar stepper motor control** in applications like printers, office automation, and industrial equipment.  
- Includes **internal Darlington transistors** with **flyback diodes** for inductive load protection.  
- Operates in **full-step mode** (2-phase excitation).  

### **Features:**  
- **High voltage and current capability** (up to 50V, 1.5A per phase).  
- **Built-in thermal shutdown** for overheating protection.  
- **Simplified control logic** (requires only step and direction signals).  
- **Low saturation voltage** for improved efficiency.  
- **Compact SIP package** for space-saving designs.  

This IC is commonly used in **low-to-medium power stepper motor applications** where unipolar drive is preferred.
