Description and Introduction

STEPPER MOTOR DRIVER The TEA3718DP is a motor driver IC manufactured by STMicroelectronics. Here are the key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
STMicroelectronics  

### **Description:**  
The TEA3718DP is a dual full-bridge driver designed for bipolar stepper motor control. It integrates power MOSFETs and logic circuitry to drive motors efficiently with minimal external components.  

### **Key Features:**  
- **Output Configuration:** Dual full-bridge  
- **Operating Voltage:** Up to **50V**  
- **Output Current:** Up to **2.5A per bridge** (peak)  
- **Control Interface:** Parallel or serial (SPI)  
- **Protection Features:**  
  - Overcurrent protection  
  - Thermal shutdown  
  - Undervoltage lockout (UVLO)  
- **Package:** PowerSO-36  

### **Applications:**  
- Bipolar stepper motor control  
- Robotics  
- Industrial automation  
- Printers and scanners  

### **Additional Specifications:**  
- **Logic Supply Voltage (VCC):** 3.3V or 5V  
- **PWM Control:** Supports chopping for current regulation

Application Scenarios & Design Considerations

STEPPER MOTOR DRIVER

Alternative Part Number

  • L298N --: Dual full-bridge motor driver in a similar power package, widely used as a drop-in functional substitute for bipolar stepper and DC motor drive applications.
  • L293D --: Quad half-H driver with similar logic-level control interface, commonly used as a lower-power alternative for the TEA3718DP in stepper motor circuits.
  • SN754410 --: Quadruple half-H driver pin-compatible in function with L293D, offering a comparable motor drive solution when the original ST part is unavailable.
