NSI6601B-DSPR

Isolators - Gate Drivers Overview

The NSI6601B-DSPR is a single-channel isolated gate driver designed for IGBT, power MOSFET, and SiC MOSFET applications. It features split outputs with 5A peak source and sink currents. The device supports an input supply voltage of 3.1V to 17V and a driver supply voltage of 13.7V to 32V. Key electrical parameters include a propagation delay of 78ns (typical), rise/fall times of 9ns/8ns, and a common-mode transient immunity of 150kV/μs. It offers 3000Vrms isolation per UL1577 standards and operates from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm isolation rating and UVLO thresholds. Ensure the SOP-8 package matches the target PCB footprint. Confirm that the 3000Vrms isolation specification meets the safety requirements of the end application. Cross-reference the operating temperature range with system thermal constraints.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with moderate 5A drive strength is required. It is suitable for applications needing split output timing control. Consider the 3000Vrms isolation limit compared to higher-rated variants if higher voltage isolation is needed. Verify compatibility with the target logic input voltage levels within the 3.1V to 17V range.

Isolators - Gate Drivers Part Context

This part belongs to the NSI6601 family of isolated gate drivers from NOVOSENSE. The family includes variants with different isolation ratings, such as the NSI6601MC which offers 5700Vrms isolation. The NSI6601 series utilizes capacitive coupling technology for signal transmission across the isolation barrier.

Isolators - Gate Drivers Replacement Considerations

NSI6601C-DSPR: Offers similar performance but may have different isolation certification or UVLO settings. NSI6601MC-DSPR: Provides higher 5700Vrms isolation and AEC-Q100 automotive qualification.
