Device Structure

Contains two N-channel MOSFETs in a half-bridge configuration. Integrated into a single compact chip using NexFET technology. Arranged for low-loss, high-efficiency switching.

Performance Characteristics

Very low Rds(on) and low gate charge for reduced conduction and switching losses. Supports logic level drive. High current capability in small footprint. Wide operating temperature range. Fast switching suitable for high-frequency applications.

Application Environments

Commonly used for DC/DC converters, synchronous buck regulators, point-of-load power supply modules, VRMs, server and computing power management, portable electronics, and high-efficiency power stages.

Selection Guidelines

Choose this device for compact half-bridge MOSFET solutions up to 15A and 30V. Suitable when logic-level gate drive and high efficiency are needed. Check power and current handling versus specific application load, and ensure compatibility with the package and footprint.

Usage Considerations

Observe safe handling for ESD-sensitive parts. Ensure good PCB heat dissipation for full 4W operation. Match gate drive voltage for optimum switching speed and efficiency. Verify layout for minimal parasitic inductance and resistance. Follow moisture and soldering guidelines since MSL is 1 (unlimited floor life).
