SI82390CB-IS1

Isolators - Gate Drivers Overview

The SI82390CB-IS1 is a dual-channel, galvanically isolated gate driver manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide signal isolation with a rated voltage of 2500 Vrms. The device features a 12 V undervoltage lockout (UVLO) and delivers a peak output current of 4 A per channel. It is housed in a 16-pin SOIC wide package and operates within a temperature range of -40 °C to +125 °C.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology for high-speed signal transmission
• Dual-channel configuration with independent high-side and low-side drivers
• Integrated undervoltage lockout for reliable operation
• High peak output current capability for driving power switches

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Power supply designs

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1 against official Skyworks documentation to confirm pinout and safety certification status. Ensure the procurement source provides valid RoHS compliance data. Cross-reference the manufacturer part number with the distributor catalog to avoid confusion with similar variants in the SI8239x series. Confirm the package type matches the required PCB footprint.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2500 Vrms isolation is required. The 4 A peak current supports standard IGBT and MOSFET switching applications. Consider the 12 V UVLO threshold for compatibility with control logic levels. The wide operating temperature range suits industrial environments. Verify that the SOIC-16 package fits the design constraints.

Isolators - Gate Drivers Part Context

This part belongs to the SI8239x family of digital isolators from Skyworks Solutions. These devices replace traditional magnetic isolators in many applications due to smaller size and lower power consumption. The SI82390 variant specifically offers dual-channel isolation with integrated gate drive capabilities, targeting high-reliability power electronics markets.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks datasheets for direct replacements within the SI8239x series. Verify pin-to-pin compatibility before substitution. Ensure isolation voltage and current ratings meet or exceed original requirements.
