L6395D

Overview

The L6395D is a high-voltage, single-chip gate driver designed for N-channel power MOSFETs and IGBTs. It integrates independent high-side and low-side drivers within an 8-SOIC package. The device supports a supply voltage range of 10 V to 20 V and withstands up to 600 V on the high side via bootstrap operation. It delivers peak output currents of 430 mA sourcing and 290 mA sinking. Typical switching times are 75 ns rise and 35 ns fall. It operates from -40°C to +150°C junction temperature with non-inverting inputs.

Feature Summary

• Integrates high-side and low-side drivers in a single chip
• Supports N-channel MOSFET and IGBT technologies
• Provides independent control for each channel

Applications

• Three-phase switched reluctance motor drives
• Asymmetric half-bridge flexible converter topologies
• General-purpose half-bridge configurations

Procurement Notes

Verify the specific suffix (e.g., D vs DTR) against the required packaging format, as tube and reel variants exist. Confirm the operating temperature grade matches the application requirements, noting the junction temperature limit. Ensure the 600 V self-bootstrapping capability aligns with the target voltage levels. Cross-reference the pinout with the official datasheet to prevent layout errors during integration.

Selection Notes

Select this component when driving N-channel devices in half-bridge arrangements requiring high-voltage isolation. The integrated bootstrap architecture simplifies circuit design by eliminating external high-side drive complexity. Consider the 430 mA source current for fast switching applications. Verify that the 10 V minimum supply voltage meets the logic interface requirements of the controlling microcontroller or PWM generator.

Part Context

This part belongs to the L6395 series of gate drivers from STMicroelectronics. It is specifically engineered for high-voltage power switching applications. The device is commonly utilized in motor control systems, including those based on asymmetric half-bridge topologies. It serves as a critical interface between low-voltage logic controllers and high-power semiconductor switches.

Replacement Considerations

Check for other members of the L6395 family that may offer different packaging options or slight parameter variations. Verify compatibility with existing PCB footprints if substituting with similar SOIC-8 gate drivers. Ensure any alternative maintains the 600 V high-side rating and comparable peak output currents.
