L6385D013TR Description

The L6385D013TR from STMicroelectronics is a high-voltage, half-bridge gate driver IC designed for robust power management applications. This obsolete surface-mount device operates with a maximum supply voltage of 17V and supports bootstrap voltages up to 600V, making it suitable for driving high-side MOSFETs or IGBTs in demanding environments. With two independent channels, it provides inverting logic inputs (VIL = 1.5V, VIH = 3.6V) and delivers peak output currents of 400mA (source) and 650mA (sink), ensuring efficient switching of power transistors. The fast switching characteristics (50ns rise, 30ns fall times) minimize switching losses, enhancing system efficiency. Packaged in 8SO and supplied in tape & reel (TR), it is ideal for automated assembly processes.

L6385D013TR Features

• High-Side Voltage Capability: Supports bootstrap operation up to 600V, enabling high-voltage applications.
• Fast Switching: 50ns rise and 30ns fall times reduce power dissipation and improve efficiency.
• High Current Drive: 400mA source / 650mA sink ensures reliable switching of power devices.
• Independent Channels: Flexible control for half-bridge or independent low-side configurations.
• Wide Logic Compatibility: 1.5V (VIL) / 3.6V (VIH) input thresholds for broad microcontroller interfacing.
• Robust Packaging: 8SO tape & reel (TR) for automated PCB assembly and high-volume production.

L6385D013TR Applications

The L6385D013TR excels in high-voltage, high-frequency switching systems, including:

• Motor Drives: Efficiently controls IGBTs/MOSFETs in BLDC or stepper motor applications.
• Switch-Mode Power Supplies (SMPS): Enhances performance in offline flyback or half-bridge topologies.
• Industrial Inverters: Provides reliable gate driving for high-power conversion systems.
• Lighting Ballasts: Optimizes switching in electronic ballasts for HID or LED drivers.

Conclusion of L6385D013TR

The L6385D013TR is a high-performance gate driver offering fast switching, high voltage tolerance, and strong drive capability, making it well-suited for industrial and power electronics applications. While marked as obsolete, its 600V bootstrap support and independent channel control remain advantageous for legacy designs requiring robust half-bridge driving. Engineers should verify alternative solutions for new designs but can rely on this IC for proven performance in motor control, SMPS, and inverter systems.
