L6574D ST Half-Bridge Gate Driver | 16-SO | 600V, 0.6A Sink/Source

Product Overview

The L6574D is a high-voltage half-bridge gate driver IC from STMicroelectronics, designed for driving N-channel power MOSFETs and IGBTs in half-bridge configurations. It features a bootstrap diode integrated on-chip, enabling high-side driving with minimal external components. The device operates with a supply voltage up to 600V and provides 0.6A sink/source drive current, making it suitable for medium-power applications. The L6574D is housed in a compact 16-SO package, offering a space-saving solution for industrial and consumer electronics.

Detailed Technical Specifications

Key Features

• Integrated bootstrap diode for high-side drive
• Under-voltage lockout (UVLO) on both VCC and VB
• Cross-conduction prevention logic
• Shutdown input for fault management
• Matched propagation delays for both channels
• High noise immunity

Target Applications

The L6574D is ideal for half-bridge and full-bridge converters, motor drives, and power inverters. Specific applications include: 5G base station power supplies, industrial motor control for conveyor belts, DC-DC converters for telecom equipment, and automotive auxiliary inverters (e.g., for electric vehicle HVAC systems). It is also used in consumer appliances like washing machine motor drives and air conditioner compressor inverters.
