The L6385D from STMicroelectronics is a high-voltage, high-speed power driver designed to drive N-channel MOSFETs or IGBTs in a half-bridge configuration. It is an advanced and efficient solution for a wide range of applications, including motor drivers, switched-mode power supplies, and power inverter circuits.

Key Features

• High-Voltage Capability: The L6385D can handle up to 600V, making it suitable for high-voltage applications.
• Integrated Bootstrap Diode: The inclusion of a high-voltage bootstrap diode simplifies the design and reduces external component count.
• Dual Independent High and Low Side Drivers: This feature allows for better control and efficiency in driving the half-bridge configuration.
• Matched Delay Propagation Times: Ensures better performance by minimizing the dead-time between high-side and low-side MOSFETs switching.
• Under-Voltage Lockout (UVLO): Protects the device and the power switches from operating at insufficient voltages.
• Cross-Conduction Prevention: Built-in interlocking function to prevent simultaneous high and low side conduction.
• CMOS/TTL Compatible Inputs: The logic inputs are compatible with a wide range of control ICs.
