SI82398BB4-IS1

Isolators - Gate Drivers Overview

The SI82398BB4-IS1 is a dual-channel, galvanically isolated gate driver from the Si8239x series by Skyworks Solutions. It features a 2500 Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. The device provides non-inverting logic with a maximum propagation delay of 40 ns, rise/fall times of 12 ns, and an output current capability of 4 A. It utilizes an 8 V UVLO threshold and is housed in a 16-pin SOIC-Narrow package. Certified under AEC-Q100 for automotive reliability, it dissipates up to 2 W of power.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Automotive power electronics
• Inverter systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R versus IS1 to confirm packaging format (Reel vs Tube) as indicated in distributor listings. Ensure the 8V UVLO specification matches the design requirement, distinguishing it from variants with different thresholds. Confirm AEC-Q100 qualification status if automotive compliance is mandatory for the project.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2500 Vrms isolation is required. The 8V UVLO setting is critical for specific gate drive voltage levels. Compare against other Si8239x variants if different UVLO thresholds or packaging options are needed. Ensure the SOIC-Narrow-16 footprint fits the PCB layout constraints.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core specifications like speed and isolation with siblings such as the SI82398CB4-IS1, which differs primarily in its UVLO threshold. The family is designed for robust performance in noisy environments using Skyworks' capacitive isolation technology.

Isolators - Gate Drivers Replacement Considerations

SI82398CB4-IS1 offers similar electrical characteristics but features a 12 V UVLO threshold instead of 8 V. Verify that the higher UVLO level does not interfere with the intended gate drive signal integrity before substitution.
