Description and Introduction

HORIZONTAL DEFLECTION POWER DRIVER The TDA8143 is a monolithic integrated circuit manufactured by SGS-THOMSON (now STMicroelectronics). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** SGS-THOMSON (STMicroelectronics)  
- **Function:** East-West Correction (EWC) IC for TV deflection systems  
- **Package:** DIP-8 (Dual In-line Package, 8 pins)  
- **Operating Voltage:** Typically **12V**  
- **Output Current:** Up to **1.5A** (peak)  
- **Frequency Range:** Designed for **horizontal deflection correction** in CRT TVs  
- **Thermal Resistance:** Specified in datasheet (exact value depends on package)  

### **Descriptions:**
- The TDA8143 is designed to provide **East-West correction** in television deflection systems, ensuring proper image geometry on CRT displays.  
- It generates a **parabolic voltage** to modulate the horizontal deflection current, compensating for pincushion distortion.  
- The IC integrates a **sawtooth generator, comparator, and output driver** for efficient correction signal generation.  

### **Features:**
- **Monolithic design** for reliable performance  
- **Low external component count** for simplified circuit design  
- **High output current capability** (up to 1.5A peak)  
- **Built-in thermal protection** to prevent overheating  
- **Wide operating voltage range** (compatible with standard TV power supplies)  
- **Adjustable correction parameters** via external resistors/capacitors  

For exact electrical characteristics and application circuits, refer to the official **SGS-THOMSON (STMicroelectronics) datasheet**.
