L6384D013TR

Overview

The L6384D013TR is a high-voltage half-bridge gate driver manufactured by STMicroelectronics, designed to drive power MOSFETs or IGBTs. It features a single input configuration with two outputs: a low-side driver providing 650 mA peak current and a high-side driver providing 400 mA. The device operates within a supply voltage range of 14.6 V to 16.6 V and supports switching frequencies up to 400 kHz. Typical rise and fall times are 50 ns and 30 ns, respectively. It includes an integrated bootstrap diode and adjustable dead-time control via the DT/SD pin. The component is housed in an 8-SOIC package and functions within a junction temperature range of -45°C to +125°C.

Feature Summary

• High-voltage floating high-side driver capable of operating on voltage rails up to 600 V using BCD offline technology.
• Integrated bootstrap diode simplifies circuit design by eliminating external components for high-side driving.
• Adjustable dead-time control allows users to prevent output cross-conduction through an external resistor connected to the DT/SD pin.
• CMOS/TTL compatible logic inputs ensure straightforward interface with standard control devices.

Applications

• Driving power MOSFETs or IGBTs in half-bridge configurations
• High-frequency motor control applications
• Power supply circuits requiring isolated high-side switching

Procurement Notes

Verify that the specific part number L6384D013TR is available from authorized distributors, as it may be listed as obsolete or end-of-life. Confirm compatibility with the replacement L6384ED013TR if sourcing alternatives is necessary. Ensure all procurement documentation references the correct manufacturer specifications and RoHS compliance status prior to ordering.

Selection Notes

Select this component for applications requiring robust high-voltage isolation and precise timing control in half-bridge topologies. Consider the 650 mA low-side and 400 mA high-side output currents when sizing gate resistors. The integrated bootstrap diode and adjustable dead-time features make it suitable for designs prioritizing compactness and protection against shoot-through currents.

Part Context

The L6384D013TR belongs to the L6384E series of high-voltage gate drivers from STMicroelectronics. This series utilizes BCD technology to integrate high-voltage capabilities with low-voltage logic interfaces. The D suffix typically denotes specific packaging or tape-and-reel variations within the broader product family, distinguishing it from tube-packaged variants like the L6384ED.

Replacement Considerations

Public confirmed substitute part numbers include L6384ED013TR.

FAQ

What is the maximum voltage rating for the high-side floating output?

The high-side portion of the L6384D013TR can operate on voltage rails up to 600 V.

How is the dead-time between high-side and low-side switching controlled?

Dead-time is adjusted by connecting an external resistor to the DT/SD pin, which prevents simultaneous conduction of both outputs.
