L6741TR

Overview

The L6741TR is a high-current, flexible dual MOSFET driver designed for synchronous rectification applications. It integrates two independent gate drivers optimized for N-channel MOSFETs. The device supports supply voltages from 5V to 12V and operates within a junction temperature range of 0°C to 125°C. It features an integrated bootstrap diode and adaptive dead-time management to ensure reliable switching. Packaged in an 8-SOIC surface-mount case with a width of 3.90mm, it facilitates compact PCB layouts.

Feature Summary

• Integrated bootstrap diode for simplified power stage design
• Adaptive dead-time management to prevent shoot-through
• Flexible gate-drive compatibility with 5V to 12V logic levels

Applications

• Synchronous-rectified DC-DC converters
• High-frequency power supply stages
• N-channel MOSFET gate driving

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm that the 8-SOIC package dimensions match your board layout constraints. Ensure the operating temperature range meets your system's thermal requirements. Check regional availability as distribution may be limited due to end-of-life status.

Selection Notes

Select this component for designs requiring integrated bootstrap functionality and adaptive dead-time control. It is suitable for applications needing flexible voltage compatibility between 5V and 12V. Consider the obsolete status when designing new products requiring long-term supply stability.

Part Context

The L6741 is part of STMicroelectronics' gate driver portfolio, specifically engineered for high-frequency operation. It serves as a dual-driver solution for synchronous rectification, replacing discrete driver configurations. The TR suffix indicates tape-and-reel packaging for automated assembly.
