LMG1205YFXT

Overview

The LMG1205YFXT is a half-bridge gate driver from Texas Instruments designed for Gallium Nitride (GaN) transistors. It features dual drivers with high-side and low-side outputs, housed in a DSBGA-12 package. The device operates on a supply voltage between 4.5 V and 5.5 V, delivering a peak output current of 5 A. Key timing parameters include a rise time of 7 ns, a fall time of 3.5 ns, and maximum delay times of 50 ns for both turn-on and turn-off states. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Optimized for driving GaN FETs with dedicated high-side and low-side channels
• Provides symmetrical switching performance with fast rise and fall times
• Integrated protection against shoot-through via configurable dead-time control

Applications

• High-frequency power conversion circuits using GaN devices
• Point-of-load converters requiring compact half-bridge topologies
• Industrial motor drives utilizing wide-bandgap semiconductors
