NSI6602VB-DSWKR

Isolators - Gate Drivers Overview

The NSI6602VB-DSWKR is a high-reliability isolated dual-channel gate driver IC from NOVOSENSE, designed for driving power transistors at switching frequencies up to 2MHz. It features a 5700Vrms isolation voltage in the SOP14 (300mil) package, compliant with UL1577 standards. The device provides peak output currents of 6A source and 8A sink, with a typical propagation delay of 25ns and maximum delay matching of 5ns. Operating supply voltages range from 9.4V to 25V on the drive side and 3V to 5.5V on the input side. It exhibits a typical common-mode transient immunity (CMTI) of 150kV/μs and operates within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• High-frequency DC-DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DSWKR' corresponds to the SOP14 (300mil) package variant offering 5700Vrms isolation when sourcing. Confirm that the component is an active part number from NOVOSENSE. Ensure compatibility with the required isolation standards for your target application. Check for any specific handling requirements related to the surface-mount technology package.

Isolators - Gate Drivers Selection Notes

Select this model when 5700Vrms isolation is mandatory for safety compliance. Choose over lower-rated variants if operating in environments with high common-mode noise or voltage spikes. Consider the 6A/8A current capability for driving larger MOSFETs or IGBTs. Verify that the SOP14 footprint fits the PCB layout constraints compared to LGA or other SOIC options.

Isolators - Gate Drivers Part Context

This component belongs to the NSI6602 family of isolated gate drivers. The family includes variants with different isolation ratings such as 2500Vrms and 3000Vrms, available in LGA13 and SOP16 packages. The VB suffix typically denotes the highest isolation rating within the series. These devices share core architecture but differ in insulation thickness and package dimensions to suit various voltage levels.

Isolators - Gate Drivers Replacement Considerations

Direct replacements may include other NSI6602 variants like NSI6602VA-DSWKR if lower isolation is acceptable. Cross-brand alternatives require matching 5700Vrms isolation, 2-channel configuration, and similar pinout compatibility. Verify electrical parameters such as CMTI and output current before substitution.
