Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ABC' against official Skyworks documentation to confirm pinout and feature set, as variations exist within the SI82Cx family. Ensure the 'ISR' suffix corresponds to the correct reel packaging configuration. Cross-reference the datasheet revision date to validate compliance with current safety certifications such as UL, CSA, and VDE before finalizing procurement specifications.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with 4 A peak current and 3750 Vrms isolation is required. It is suitable for applications needing both inverting and non-inverting outputs from one device. Consider the 8-SOIC package size for PCB layout constraints. Verify that the operating temperature range of -40°C to +125°C meets the environmental requirements of the target application.

Isolators - Gate Drivers Part Context

This part belongs to the Si82Cx series of isolated gate drivers from Skyworks Solutions. The series is characterized by its use of silicon dioxide (SiO2) capacitive coupling technology, which offers superior performance compared to traditional magnetic or optical isolation methods. The SI82C70 variant specifically targets single-channel applications requiring high-speed switching and robust isolation capabilities.
