NXF6501DC-Q100Z

Overview

The NXF6501DC-Q100Z is a low-noise transformer driver designed for isolated power supplies in automotive applications. It operates on a 2.25V to 5.5V supply and features an internal 410kHz oscillator. The device provides high output drive with 1.2A current capability at 5V and includes integrated protection such as current limiting, UVLO, thermal shutdown, and soft-start. Qualified to AEC-Q100 Grade 1, it supports push-pull topologies with center-tapped transformers.

Feature Summary

• Optimized for low EMI via slew rate control and spread spectrum clocking
• Integrated comprehensive protection including current limit, UVLO, and thermal shutdown
• Soft-start functionality prevents high inrush currents during power-up
• Supports functional safety requirements for automotive systems

Applications

• Automotive isolation for CAN, RS-485, and RS-422 interfaces
• Low noise isolated USB power supplies
• Process control and telecom power systems
• Battery management systems and onboard chargers

Procurement Notes

Verify the specific suffix DC against the official Nexperia datasheet to confirm package type and tape/reel specifications. Ensure the Q100 qualification grade matches the project's automotive reliability requirements. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the ordering code with the manufacturer's latest documentation to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component for designs requiring compact isolation solutions with strict EMI constraints. The 410kHz frequency allows for smaller magnetic components compared to lower-frequency drivers. The wide input voltage range accommodates various automotive battery architectures. Ensure the load does not exceed the 1.7A current limit to maintain safe operation within the specified temperature range.

Part Context

This part belongs to Nexperia's specialized power management portfolio tailored for connected vehicles. It complements other discrete and logic devices qualified under AEC standards. The series focuses on enabling efficient, reliable power conversion in space-constrained automotive electronics, supporting trends toward higher integration and reduced electromagnetic interference.

Replacement Considerations

Check for direct substitutes like the PNXF6501DC-Q100 if available. Verify that any alternative maintains the same 5-pin TSOT-23 footprint and AEC-Q100 Grade 1 qualification. Ensure equivalent drive strength and protection features are present before substitution.
