Description and Introduction

VERTICAL DEFLECTION CIRCUIT The TDA1675A is a vertical deflection processor IC manufactured by SGS-THOMSON (now STMicroelectronics).  

### **Specifications:**  
- **Function:** Vertical deflection processor for TV and monitor applications.  
- **Supply Voltage (Vcc):** Typically operates at **12V to 18V**.  
- **Output Current:** Capable of driving vertical deflection coils.  
- **Frequency Range:** Designed for standard vertical deflection frequencies (50Hz/60Hz).  
- **Package:** Typically available in a **16-pin DIP (Dual In-line Package)**.  

### **Descriptions and Features:**  
- **Integrated Vertical Deflection System:** Combines synchronization, oscillator, and driver stages.  
- **Internal Protection:** Includes thermal shutdown and short-circuit protection.  
- **Low External Component Count:** Reduces design complexity.  
- **Sawtooth Waveform Generation:** Provides stable vertical deflection signals.  
- **Wide Operating Voltage Range:** Suitable for various CRT display applications.  

This IC was commonly used in CRT-based TVs and monitors for vertical scanning control.
