Description and Introduction

Unipolar Fixed-Current Chopper-Type 4-Phase Stepping Motor Driver The STK6712BMK4 is a hybrid IC (integrated circuit) manufactured by Sanyo (now part of ON Semiconductor). It is designed for motor drive applications, specifically for controlling stepping motors. Below are the key specifications, descriptions, and features based on available data:

### **Specifications:**  
- **Manufacturer:** Sanyo (ON Semiconductor)  
- **Type:** Hybrid IC (Thick Film)  
- **Function:** Stepping Motor Driver  
- **Output Current:** Up to 2.0A (per phase)  
- **Supply Voltage (VCC):** 12V to 40V (recommended operating range)  
- **Logic Supply Voltage (VDD):** 4.5V to 5.5V  
- **Package:** SIP (Single In-line Package)  
- **Number of Pins:** 15  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
- The STK6712BMK4 is a unipolar stepping motor driver IC with built-in power MOSFETs for driving two-phase stepping motors.  
- It includes a built-in thermal shutdown circuit for protection against overheating.  
- The IC supports full-step, half-step, and microstepping modes for precise motor control.  
- It is commonly used in office automation equipment, industrial machinery, and robotics.  

### **Features:**  
- **High Output Current:** Capable of driving motors up to 2.0A per phase.  
- **Built-in Protection Circuits:** Includes thermal shutdown and overcurrent protection.  
- **Wide Voltage Range:** Supports motor supply voltages from 12V to 40V.  
- **Low Power Consumption:** Logic supply operates at 5V, reducing power dissipation.  
- **Compact SIP Package:** Space-saving design suitable for PCB mounting.  

This information is based on manufacturer datasheets and technical documentation. For exact application details, refer to the official datasheet.
