SN6501DBVT Transformer Driver IC

Description

The SN6501DBVT is a push-pull transformer driver IC from Texas Instruments, designed to provide isolated power supply solutions. It operates with an input voltage range of 3V to 5.5V and is commonly used in conjunction with a transformer to generate isolated power for various applications. The device is available in a compact SOT-23-5 package, making it suitable for space-constrained designs.

Key Features:

• Push-Pull Driver: Drives low-profile centre-tapped transformers for creating isolated power supplies.
• Wide Input Voltage Range: Operates from 3V to 5.5V, compatible with standard power rails.
• High Switching Frequency: Operates at up to 350kHz, allowing the use of small transformers and capacitors.
• Integrated Soft-Start: Minimizes inrush current during power-up, ensuring stable startup behavior.
• Low Quiescent Current: Efficient operation with low power consumption in idle states.
• Thermal Shutdown Protection: Prevents overheating under fault conditions.

Applications:

• Isolated power supplies for data isolation in industrial and medical devices.
• Powering isolated interface circuits such as RS-485, CAN, and RS-232 transceivers.
• Isolated gate drivers for power electronics.
• Battery-powered systems require isolated power conversion.
