NV6525

Overview

The NV6525 is a GaNSafe™ power switch and driver integrating an N-channel Gallium Nitride (GaN) transistor with a dedicated gate driver in a TOLT-16L package. It features a 650V voltage rating, a maximum continuous current of 65A, and a typical on-resistance of 25 milliohms. The device operates with a supply voltage range of 11V to 18V and supports a 1:1 input-to-output ratio. It includes controlled slew rate technology for electromagnetic interference reduction and offers comprehensive fault protection mechanisms.

Feature Summary

• Integrates a high-voltage N-channel GaN power switch with a specialized gate driver in a single surface-mount package.
• Incorporates controlled slew rate technology to optimize switching performance and reduce electromagnetic interference emissions.
• Provides integrated hardware-level protection against over-current, short circuits, and thermal overload conditions.

Applications

• High-efficiency AC-DC power adapters
• Server and data center power supplies
• Industrial motor drives

Procurement Notes

Verify the specific ordering suffix to confirm the correct packaging configuration, such as tape and reel or cut tape, prior to procurement. Ensure that the design environment supports the specified operating temperature range of -40°C to 150°C junction temperature. Confirm compliance with RoHS3 standards and check the moisture sensitivity level requirements for proper storage and handling procedures during assembly.

Selection Notes

Select this component for designs requiring high current density and integrated protection in a compact form factor. The 65A capability and low on-resistance make it suitable for applications demanding high efficiency. Consider the 16-pin PowerSOP module footprint for PCB layout constraints. Evaluate the need for external compensation, as the internal driver simplifies control loop design compared to discrete solutions.

Part Context

This part belongs to the GaNSafe™ series from Navitas Semiconductor, which combines silicon control logic with gallium nitride power devices. The TOLT-16L package provides enhanced thermal dissipation and electrical isolation capabilities compared to standard plastic packages. This integration reduces system complexity by eliminating the need for separate gate driver components and associated passive elements.

Replacement Considerations

Direct replacements require matching the 650V rating, 65A current capacity, and 16-pin TOLT-16L package. Verify that alternative GaN power switches offer comparable on-resistance and integrated protection features to maintain system reliability and efficiency targets without redesigning the gate drive circuitry.

FAQ

What type of fault protection is integrated into the NV6525?

The NV6525 includes fixed over-current limiting, thermal shutdown, and short-circuit protection to safeguard the device under abnormal operating conditions.

What is the recommended supply voltage range for the gate driver?

The device requires a supply voltage (Vcc/Vdd) between 11V and 18V to operate the internal gate driver correctly.
