SI8237AC-D-IS1

Isolators - Gate Drivers Overview

The SI8237AC-D-IS1 is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It features a 3.75 kV isolation rating and a 5 V undervoltage lockout (UVLO). The device utilizes capacitive coupling technology for signal transmission across the isolation barrier. It operates within a temperature range of -40°C to 125°C and is housed in a 16-SOIC package.

Isolators - Gate Drivers Feature Summary

• Dual-channel capacitive coupling architecture for high-speed signal isolation
• Integrated 5 V undervoltage lockout mechanism for reliable operation
• High common-mode transient immunity capability
• Automotive-grade qualification compliant with AEC-Q100 standards

Isolators - Gate Drivers Applications

• Industrial motor drives requiring robust isolation
• Inverter systems in renewable energy applications
• Automotive power electronics and control modules
• High-voltage switching circuits in industrial automation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D-IS1' against the official Skyworks datasheet to confirm pinout and packaging specifications. Ensure that the 3.75 kV isolation rating aligns with your system's safety requirements. Cross-reference the AEC-Q100 automotive grade status if applicable to your design. Confirm RoHS compliance details through the manufacturer's current documentation before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated gate driver with 3.75 kV isolation is required. The 5 V UVLO setting suits low-voltage logic interfaces. Consider the 16-SOIC package for surface-mount assembly constraints. Evaluate the capacitive coupling technology for noise immunity needs compared to magnetic alternatives. Verify thermal performance within the -40°C to 125°C operating range for your specific environment.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers from Skyworks Solutions. The family includes variants with different isolation ratings and UVLO thresholds, such as the SI8237BB series which offers 2.5 kV isolation. The SI8237AC-D-IS1 specifically targets applications demanding higher isolation voltage than the BB variant while maintaining compact SOIC packaging.

Isolators - Gate Drivers Replacement Considerations

The SI8237BB-D-IS1 is a related part within the same family but provides 2.5 kV isolation instead of 3.75 kV. Verify if the lower isolation rating meets your safety margins. Other Si823x variants may differ in UVLO levels or channel configurations. Direct substitution requires confirming identical pinouts and electrical characteristics beyond isolation voltage.
