L6386ADTR

Overview

The L6386ADTR is a high-voltage half-bridge gate driver manufactured by STMicroelectronics using BCD offline technology. It drives one high-side and one low-side power MOSFET or IGBT simultaneously. The floating high-side section supports voltage rails up to 600 V. Outputs independently sink 650 mA and source 400 mA. Supply voltage ranges from -300 mV to 17 V. Switching times are 50 ns rise and 30 ns fall with a 1 nF load. Operating temperature spans -45°C to +125°C. It features CMOS/TTL Schmitt trigger inputs, UVLO protection, and an integrated bootstrap diode in a SOIC-14 package.

Feature Summary

• High-voltage rail capability up to 600 V for the floating high-side section
• Integrated bootstrap diode for compact and reliable solution design
• CMOS/TTL compatible inputs with hysteresis and pull-down resistors
• Built-in overcurrent protection via internal comparator and diagnostic output

Applications

• Asymmetrical half-bridge configurations
• IGBT gate driving
• N-channel MOSFET gate driving
• Offline power supply applications

Procurement Notes

Verify the specific suffix 'ADTR' corresponds to the SOIC-14 tape and reel packaging variant. Confirm that the device meets the required 600 V high-side voltage rating and current sourcing capabilities for the target application. Ensure compatibility with the specified operating temperature range of -45°C to +125°C. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single IC is needed to drive both high-side and low-side switches in a half-bridge topology. It is suitable for applications requiring simultaneous switching with independent current sinking and sourcing capabilities. Consider the integrated bootstrap diode and UVLO features for simplified circuit design. Verify input logic compatibility with the controlling microcontroller or DSP.
