The L6386-8 from STMicroelectronics is a high-voltage gate driver specifically designed to drive both the high-side and low-side N-channel MOSFETs in a half-bridge configuration. This advanced and integrated solution is ideal for a wide range of power conversion applications, such as motor drives, uninterruptible power supplies (UPS), and power inverters for renewable energy systems.

Key Features

• High-Voltage Capability: The L6386-8 can handle high-voltage levels, with a Vboot voltage up to 600V, making it suitable for applications that require robust performance in challenging environments.
• Integrated Bootstrap Diode: The inclusion of an integrated high-voltage bootstrap diode simplifies the design by reducing the number of external components required.
• Matched Propagation Delays: The device ensures matched propagation delays for both high-side and low-side gate drives, improving the reliability and efficiency of the power stage.
• Under-Voltage Lockout (UVLO): Both the high-side and low-side drivers feature UVLO protection to ensure the device operates only when the supply voltage is sufficient, preventing potential damage from under-voltage conditions.
• CMOS and TTL Compatible Inputs: The L6386-8 is designed to interface seamlessly with a wide range of control ICs thanks to its CMOS and TTL compatible input thresholds.

Applications

The versatility of the L6386-8 makes it an excellent choice for a variety of half-bridge and full-bridge applications, including:

• Brushed and brushless motor drives
• DC-AC inverters for solar and wind power systems
• Power supplies and UPS systems
• Power factor correction circuits
