Device Structure

Consists of two synchronous, non-inverting gate drivers for a half-bridge structure. Built in 8-pin SOIC package for compact surface mount use. Utilizes a bootstrap circuit for high side driving. Supports both IGBTs and N-channel MOSFETs.

Performance Characteristics

Fast rise and fall time for quick switching (70ns rise, 35ns fall). Can drive high-side at up to 600V, enabling use in high-voltage applications. Strong sink current for robust switch turn-off. Operates at extreme temperatures from -40°C to 150°C.

Application Environments

Widely used in motor drive circuits, switch-mode power supplies, DC-DC converters, solar inverters, and uninterruptible power supplies. Suitable for industrial, consumer, and automotive power management. Ideal for high-efficiency and high-voltage switching applications.

Selection Guidelines

Choose this IC for driving half-bridge IGBT or N-channel MOSFETs in circuits up to 600V. Match the supply voltage range (10–20V) with your system. Select when you need robust operation, fast switching, and RoHS3 compliance. Verify that the mounting type (8-SOIC surface mount) fits your PCB design.

Usage Considerations

Ensure bootstrap capacitor sizing and voltage levels are correct for your load and switching frequency. Pay attention to PCB layout for high voltage isolation and minimizing noise. Confirm that the peak output current meets the requirements of your power switches. Watch MSL handling for moisture sensitivity, especially before soldering.
