SI82398CB4-IS1R

Isolators - Gate Drivers Overview

The SI82398CB4-IS1R 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 and rise/fall times of 12 ns. It delivers a peak output current of 4 A and includes a 12 V Under-Voltage Lockout (UVLO). Powered by a 2.5 V to 5.5 V input supply, it consumes 7.3 mA of operating current. Packaged in a 16-SOIC reel for surface mount applications, it supports high electromagnetic immunity.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control and power stages using digital technology
• Delivers high peak drive current for efficient switching of power devices
• Ensures signal integrity through high electromagnetic immunity characteristics
• Integrates under-voltage lockout to prevent improper operation during low supply conditions

Isolators - Gate Drivers Applications

• Industrial motor drives requiring robust isolation
• Inverter circuits in renewable energy systems
• High-frequency switching power supplies
• Automotive power electronics compliant with AEC-Q100 standards

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R indicates tape-and-reel packaging rather than tube packaging when ordering. Confirm that the 2500 Vrms isolation rating meets the safety requirements of your target application. Ensure compatibility with the 16-SOIC footprint on your PCB layout. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2500 Vrms isolation is required. It is suitable for designs needing 4 A peak current capability and fast switching speeds. Consider the 12 V UVLO threshold if driving specific gate voltages. The SOIC-16 package is appropriate for standard surface mount assembly processes.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers. It shares core specifications with variants like SI82398CB4-IS1 but differs in packaging format. The family is designed for industrial and automotive applications requiring reliable galvanic isolation.

Isolators - Gate Drivers Replacement Considerations

SI82398CB4-IS1 is a pin-compatible alternative available in tube packaging instead of reel.
