Description and Introduction

Stepper Motor Drive Circuit The UC3717 is a stepper motor driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 10V to 35V  
- **Output Current:** Up to 1A per phase (with external MOSFETs)  
- **Logic Supply Voltage (VDD):** 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The UC3717 is a bipolar stepper motor driver designed for unipolar drive applications.  
- It includes built-in protection features such as thermal shutdown and under-voltage lockout.  
- The device requires external power MOSFETs to drive the motor phases.  

### **Features:**  
- **Unipolar Stepper Motor Drive:** Supports full-step, half-step, and microstepping modes.  
- **Built-in Protection:** Thermal shutdown and under-voltage lockout for safe operation.  
- **TTL/CMOS Compatible Inputs:** Easy interfacing with microcontrollers and logic circuits.  
- **Adjustable Current Control:** Allows setting the motor phase current via external sense resistors.  
- **Low Power Consumption:** Efficient power management for reduced heat dissipation.  

The UC3717 is commonly used in applications requiring precise stepper motor control, such as printers, robotics, and industrial automation.
