L6747CTR

Overview

The L6747CTR is a half-bridge gate driver IC manufactured by STMicroelectronics, designed for synchronous N-channel MOSFET applications. It operates with a supply voltage range of 5V to 12V and supports a maximum high-side bootstrap voltage of 41V. The device features a non-inverting input type and delivers a peak output current of 3.5A. Packaged in an 8-VFDFPN (3x3) surface-mount configuration with a bare pad, it functions within a junction temperature range of 0°C to 125°C. Logic thresholds are defined at 0.8V for VIL and 2V for VIH.

Feature Summary

• Synchronous half-bridge driving capability for N-channel MOSFETs
• Non-inverting logic input interface for straightforward control integration
• Robust thermal performance supporting operation up to 125°C junction temperature

Applications

• Motor control systems requiring synchronous rectification
• DC-DC converter topologies utilizing half-bridge configurations
• Power supply circuits managing N-channel MOSFET switching

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm that the 8-VFDFPN package dimensions align with PCB footprint requirements. Ensure design compatibility with the specified 5V to 12V supply range and 41V bootstrap limit before finalizing procurement plans.

Selection Notes

Select this component when a compact half-bridge driver with 3.5A peak current is required for N-channel MOSFETs. Consider the 8-VFDFPN package size for space-constrained designs. Validate that the operating temperature range meets system thermal constraints and that the non-inverting input logic levels match the controlling microcontroller outputs.

Part Context

The L6747CTR belongs to the L6747 series of gate drivers from STMicroelectronics. It is specifically engineered for power management applications involving synchronous rectification. The CTR suffix indicates a specific tape-and-reel packaging variant within the product line, distinct from other packaging options like cut tape.
