SI82395CB-IS1R

Isolators - Gate Drivers Overview

The SI82395CB-IS1R is a dual-channel, galvanically isolated gate driver manufactured by Skyworks Solutions Inc. It features capacitive coupling technology with a 2500 Vrms isolation voltage and operates within an extended temperature range of -40°C to +125°C. The device provides a peak output current of 4 A per channel and supports a supply voltage up to 12 V. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns, and a typical quiescent current of 7.2 mA. It is housed in a 16-SOIC package and is qualified under the AEC-Q100 standard for automotive applications.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology ensures high electromagnetic immunity and robust signal integrity
• Dual isolated channels provide independent control for high-side and low-side switching
• Integrated undervoltage lockout (UVLO) protects against improper operation during power transitions
• AEC-Q100 qualification ensures reliability for demanding automotive environments

Isolators - Gate Drivers Applications

• Automotive motor control systems
• High-frequency DC-DC converters
• Industrial inverters and drives

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R indicates reel packaging when sourcing components. Confirm that the 2500 Vrms rating aligns with system insulation requirements. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for AEC-Q100 certification if automotive compliance is mandatory. Validate input logic levels against the specified TTL threshold range.

Isolators - Gate Drivers Selection Notes

Select this component for designs requiring high-speed switching with strong noise immunity. The dual-channel architecture simplifies half-bridge configurations. Consider the 4 A drive strength for medium-power MOSFETs or IGBTs. The wide operating temperature range suits harsh industrial or automotive conditions. Verify that the 12 V UVLO threshold matches the target gate drive voltage.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers from Skyworks Solutions. The series utilizes silicon dioxide-based capacitive isolation for superior performance compared to traditional magnetic or optical methods. The CB-IS1R variant specifically denotes the narrow SOIC package and reel format, distinguishing it from tube-packaged counterparts like the SI82395CB-IS1.

Isolators - Gate Drivers Replacement Considerations

The SI82395CD-IS serves as a pin-compatible alternative within the same family but utilizes a wide SOIC package. Verify package dimensions and thermal characteristics before substitution. Both parts share similar electrical specifications and isolation ratings.
