NV6524

Overview

The NV6524 is a GaNSafe power switch and controller from Navitas Semiconductor, Inc., designed for high-efficiency power conversion. It integrates a 650V N-channel GaN transistor with a dedicated driver in a TOLT-16L surface-mount package. The device features a typical on-resistance of 18mOhm and supports a maximum output current of 90A. It operates with a supply voltage range of 11V to 18V and includes non-inverting input logic. The component offers controlled response speed and built-in protection against fixed current limits, overtemperature conditions, and short circuits, functioning within a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates a 650V N-channel GaN power switch with a dedicated gate driver in a single compact package.
• Includes comprehensive fault protection mechanisms such as fixed current limiting, overtemperature shutdown, and short-circuit protection.
• Features controlled response speed to optimize switching performance and minimize electromagnetic interference.

Applications

• High-density AC-DC power adapters
• DC-DC converter modules
• Server and data center power supplies

Procurement Notes

Verify the specific ordering suffix (e.g., TR, CT, DKR) to confirm the required packaging format, such as tape and reel or cut tape, before finalizing procurement. Ensure that the requested quantity aligns with the manufacturer's standard lead times, which may require additional processing time due to high demand volumes. Confirm that the application environment stays within the specified operating temperature range and voltage parameters.

Selection Notes

Select this component for designs requiring high power density and efficiency in wide-bandgap applications. The integrated driver simplifies circuit design by eliminating external gate drive components. Consider the 18mOhm on-resistance for thermal management and the 90A current capability for load requirements. The TOLT-16L package offers a balance between thermal performance and footprint size for surface-mount assembly.

Part Context

The NV6524 belongs to the GaNSafe series from Navitas Semiconductor, which combines gallium nitride transistors with proprietary control ICs. This series targets next-generation power supplies that demand higher efficiency and smaller form factors compared to traditional silicon-based solutions. The integration of the driver and switch reduces system complexity and improves reliability by minimizing parasitic inductances associated with discrete layouts.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should consult official cross-reference guides or contact the manufacturer directly for potential alternatives if this specific model becomes unavailable.
