SI8234BB-C-IS1R

Isolators - Gate Drivers Overview

The SI8234BB-C-IS1R is a dual-channel digital isolator gate driver from Skyworks Solutions, utilizing capacitive coupling technology. It provides 2.5 kVRMS isolation voltage and supports high-side and low-side configurations. The device features a 4 A peak output current capability and operates within a temperature range of -40°C to +125°C. It is housed in a 16-SOIC package and includes an 8 V under-voltage lockout (UVLO) feature for reliable operation.

Isolators - Gate Drivers Feature Summary

• Dual isolated drivers integrated into a single package
• Capacitive coupling technology for signal transmission

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' against official Skyworks documentation to confirm insulation rating and UVLO thresholds. Ensure the 'IS1R' designation matches the required tape-and-reel packaging format. Cross-reference the datasheet revision date to validate technical parameters before integration.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel solution with 2.5 kVRMS isolation is required. The 4 A drive strength suits medium-power switching loads. Verify compatibility with the target logic family and ensure the SOIC-16 footprint fits the PCB layout constraints.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x series of isolated gate drivers. It complements other variants like the SI8234AB and SI8234BD by offering specific isolation ratings and UVLO levels within the same functional family.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include SI8234BB-D-IS and SI8234BB-AM. Verify that alternative parts match the 2.5 kVRMS isolation and 4 A drive current requirements.
