Description and Introduction

STEPPER MOTOR DRIVER The TEA3718SP is a motor driver IC manufactured by STMicroelectronics. Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics (ST)  

### **Specifications:**  
- **Type:** Stepper Motor Driver  
- **Operating Voltage:** 8V to 45V  
- **Output Current:** Up to 1.5A (per phase)  
- **Control Interface:** Step and Direction  
- **Microstepping:** Up to 1/16 step  
- **Protection Features:** Overcurrent, thermal shutdown, and undervoltage lockout  
- **Package:** PowerSO-20  

### **Descriptions:**  
The TEA3718SP is a bipolar stepper motor driver designed for high-efficiency motor control applications. It integrates PWM current control and protection mechanisms, making it suitable for industrial and consumer applications.  

### **Features:**  
- **High Efficiency:** PWM current control reduces power dissipation.  
- **Flexible Microstepping:** Supports full, half, quarter, and 1/16 step modes.  
- **Integrated Protection:** Includes thermal shutdown, overcurrent, and undervoltage lockout.  
- **Wide Voltage Range:** Operates from 8V to 45V, accommodating various motor types.  
- **Low Power Standby Mode:** Enhances energy efficiency when idle.  

This information is based on STMicroelectronics' official documentation. For detailed technical specifications, refer to the datasheet.

Application Scenarios & Design Considerations

STEPPER MOTOR DRIVER

Alternative Part Number

  • L298N --: Dual full-bridge motor driver in a Multiwatt package, widely used as a higher-current substitute for the TEA3718 in stepper and DC motor drive applications.
  • L293D --: Quad half-H driver with similar logic-level control interface, commonly used as a drop-in functional replacement for small stepper motor driver stages.
  • SN754410 --: Quadruple half-H driver with pin-compatible logic inputs and comparable drive capability, suitable for replacing the TEA3718 in low-to-medium power motor control circuits.
