Professional IC Distribution & Technical Solutions

The TDA4853 is an integrated circuit (IC) manufactured by NXP Semiconductors, designed for use in multi-sync deflection controllers for monitors and displays.

Specifications:

• Supply Voltage (VCC): 10.8V to 16V (typical 12V)
• Operating Temperature Range: -20°C to +85°C
• Package: DIP-20 (Dual In-line Package, 20 pins)
• Horizontal Frequency Range: 15kHz to 150kHz
• Vertical Frequency Range: 50Hz to 160Hz
• Power Consumption: Low power consumption for efficient operation

Descriptions:

The TDA4853 is a deflection controller IC that provides horizontal and vertical synchronization for CRT (Cathode Ray Tube) monitors. It supports multi-sync operation, making it suitable for a wide range of display resolutions and refresh rates. The IC includes built-in protection features such as X-ray protection and overvoltage protection.

Features:

• Horizontal and Vertical Deflection Control: Generates drive signals for horizontal and vertical deflection circuits.
• Multi-Sync Capability: Supports a wide range of horizontal and vertical frequencies.
• X-Ray Protection: Prevents excessive high voltage by shutting down the horizontal driver in case of fault conditions.
• Soft Start Function: Reduces stress on components during power-up.
• B+ Voltage Regulation: Controls the secondary power supply for stable operation.
• Sync Processing: Handles composite sync signals for synchronization.
• Adjustable Parameters: Allows tuning of parameters such as picture size and position.

The TDA4853 is commonly used in CRT monitors and older display systems requiring precise deflection control.
