L6386D013TR

L6386D013TR Description

The L6386D013TR from STMicroelectronics is a high-voltage, half-bridge gate driver IC designed for robust power management applications. This surface-mount device comes in a 14-pin SO package and is supplied in Tape & Reel (TR) for automated assembly. With a maximum supply voltage of 17V and 600V bootstrap capability, it is engineered to drive N-channel power MOSFETs or IGBTs in high-side/low-side configurations. The dual-channel, independent driver architecture ensures precise control, while its inverting logic inputs (compatible with 1.5V–3.6V logic levels) simplify interfacing with microcontrollers or PWM controllers.

L6386D013TR Features

• High-Side Voltage Support: Up to 600V bootstrap voltage for high-voltage applications.
• Fast Switching: 50ns rise time and 30ns fall time minimize switching losses, enhancing efficiency.
• High Current Drive: 400mA source / 650mA sink peak output current ensures reliable gate charging/discharging.
• Robust Protection: Undervoltage lockout (UVLO) and interlocking prevent shoot-through in half-bridge setups.
• Wide Compatibility: Works with 3.3V/5V logic (VIL=1.5V, VIH=3.6V) for flexible system integration.
• Reliability: ROHS3 compliant and REACH unaffected, with MSL 1 (unlimited) moisture sensitivity for long-term stability.

L6386D013TR Applications

This gate driver excels in high-performance power systems, including:

• Motor Drives: Ideal for BLDC/PMSM motor control in industrial automation and automotive systems.
• Switched-Mode Power Supplies (SMPS): Enhances efficiency in AC-DC converters and DC-DC topologies.
• Inverters: Suitable for solar inverters and UPS systems due to high-voltage tolerance.
• Lighting: Drives LED drivers and ballast controllers with precision.

Conclusion of L6386D013TR

The L6386D013TR stands out for its high-voltage capability, fast switching, and robust protection features, making it a preferred choice for demanding power electronics designs. While obsolete, its performance remains competitive in legacy systems requiring reliable half-bridge driving. Engineers should consider alternative STMicroelectronics models for new designs but can leverage this IC’s proven reliability in existing applications.
