MASTERGAN1LTR

Full Half-Bridge (H Bridge) Drivers Overview

The MASTERGAN1LTR is a tape-and-reel variant of the MASTERGAN1 high-power-density half-bridge driver. It integrates two 650 V enhancement-mode GaN HEMTs with an embedded gate driver in a compact System-in-Package (SiP). The device features a low-side on-resistance of 150 mΩ and supports a maximum drain current of 10 A. It includes built-in UVLO protection, interlocking functions to prevent cross-conduction, and a dedicated shutdown pin. The input voltage range is compatible with 3.3 V to 15 V logic levels.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify that the specific suffix 'LTR' corresponds to the tape-and-reel packaging format rather than bulk or cut-tape options. Confirm the package type remains the standard QFN configuration associated with the MASTERGAN1 family. Ensure compatibility with existing board layouts designed for the non-reel version if substitution is considered.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when high power density and simplified layout are required for half-bridge topologies. The integrated nature reduces bill-of-materials complexity compared to discrete solutions. Consider the operating temperature range of -40°C to 125°C for industrial environments. Evaluate the need for the specific reel packaging for automated assembly processes.

Full Half-Bridge (H Bridge) Drivers Part Context

MASTERGAN1 is part of STMicroelectronics' MasterGaN platform, representing the first generation of advanced System-in-Package solutions combining GaN transistors with optimized gate drivers. This family aims to replace traditional MOSFET-based designs by leveraging higher switching frequencies and reduced parasitic effects inherent to Gallium Nitride technology.
