NV6523-RA

Overview

The NV6523-RA is a GaNFast power IC integrating a 650V N-channel GaN transistor with a dedicated gate driver in a TOLT-16L package. It features a typical on-resistance of 32 milliohms and supports a maximum output current of 53A. The device operates within a junction temperature range of -40°C to 150°C and includes integrated fault protection for overcurrent, overtemperature, and short circuits.

Feature Summary

• Integrates a high-voltage GaN power switch with a non-inverting gate driver in a single compact package.
• Features controlled slew rate capabilities to optimize electromagnetic interference performance during switching transitions.
• Includes built-in hardware protections such as fixed overcurrent limiting, thermal shutdown, and short-circuit detection.

Applications

• AC-DC power conversion systems
• DC-DC converter modules
• Critical Conduction Mode (CrM) or Continuous Conduction Mode (CCM) Transition-Mode Power Factor Correction (TP-PFC)
• Synchronous half-bridge and full-bridge topologies
• Three-phase motor drives and buck/boost converters

Procurement Notes

Verify the specific suffix 'RA' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement source provides valid RoHS3 compliance documentation. Confirm that the TOLT-16L package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component for designs requiring high power density and efficient thermal management in AC-DC and DC-DC applications. The integrated driver simplifies layout by reducing external component count. Consider the 32 milliohm on-resistance for conduction loss calculations and verify that the 53A current rating exceeds peak load demands under worst-case operating conditions.

Part Context

This part belongs to the GaNFast family from Navitas Semiconductor, designed to replace traditional silicon MOSFETs and discrete drivers. It targets high-efficiency power supplies where size and weight are critical constraints. The integration of control logic with the power stage enables faster switching speeds compared to conventional silicon-based solutions.

Replacement Considerations

Direct substitutes require matching the 650V rating, N-channel configuration, and TOLT-16L package. Verify equivalent on-resistance and drive current capabilities. Cross-reference with other NV65xx series variants only if pinouts and electrical parameters are explicitly confirmed identical by the manufacturer.
