LMG1205YFXR

Overview

The LMG1205YFXR is a half-bridge gate driver designed for Gallium Nitride (GaN) transistors. It features two independent drivers with 5 A output current capability. The device operates on a 4.5 V to 5.5 V supply. It provides fast switching performance with a 7 ns rise time and 3.5 ns fall time. Propagation delays are limited to 50 ns maximum for both turn-on and turn-off states. The component functions within an ambient temperature range of -40°C to +125°C and is housed in a DSBGA-12 package.

Feature Summary

• Integrated high-side and low-side driver configuration optimized for GaN devices
• Fast switching characteristics with nanosecond-level rise and fall times
• Symmetrical propagation delay limits ensuring precise timing control

Applications

• Driving enhancement-mode GaN power transistors
• High-frequency DC-DC converter topologies
• Resonant power conversion circuits

Procurement Notes
