STG6384QTR

Overview

The STG6384QTR is a high-voltage half-bridge gate driver manufactured by STMicroelectronics using BCD technology. It drives power MOSFETs or IGBTs with a floating high-side section supporting up to 600 V rails. The device provides 650 mA sink and 400 mA source output currents, with rise/fall times of 50 ns/30 ns under 1 nF load. It features CMOS/TTL compatible inputs, integrated bootstrap diode, UVLO protection, and user-tunable deadtime via an external resistor on the DT/SD pin. Operating temperature ranges from -40°C to +125°C in SO-8 tape and reel packaging.

Feature Summary

High voltage rail capability up to 600 V for driving power switches
Integrated bootstrap diode and dV/dt immunity of ±50 V/nsec
User-configurable deadtime control via external resistor
CMOS/TTL Schmitt trigger inputs with hysteresis

Applications

Motor control systems
Power supply inverters
Industrial motor drives

Procurement Notes

Verify the exact suffix 'QTR' against official STMicroelectronics documentation to confirm package type (SO-8) and reel specifications. Ensure the component meets automotive qualification standards if required for the specific application environment. Cross-reference datasheet revision numbers to validate parameter consistency.

Selection Notes

Select this component when a robust half-bridge driver with high dV/dt immunity and integrated bootstrap functionality is needed. The single-input configuration simplifies control logic but requires careful timing management. Verify that the external deadtime resistor values align with the desired switching frequency and cross-conduction prevention requirements.

Part Context

The STG6384QTR belongs to the L6384E family of high-voltage gate drivers. It shares core electrical characteristics with the L6384ED and L6384ED013TR variants, differing primarily in packaging and potential automotive-grade qualification indicated by the 'G' and 'Q' designators. It serves as a direct replacement for standard L6384E devices in space-constrained designs requiring tape-and-reel delivery.
