SI8233CB-AM

Isolators - Gate Drivers Overview

The SI8233CB-AM is a dual-channel, galvanically isolated gate driver from Skyworks Solutions Inc., utilizing silicon isolation technology. It features two independent high-side and low-side drivers within a single package, providing up to 5 kVRMS input-to-output isolation and 1500 VDC peak driver-to-driver voltage. The device supports output supply voltages ranging from 9.4V to 24V and delivers a peak output current of 4A. It operates with a maximum propagation delay of 60ns and includes under-voltage lockout (UVLO) for reliable switching. Designed for automotive applications, it meets AEC-Q100 standards and functions across an extended temperature range.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AM' against official Skyworks documentation to confirm pinout, insulation rating, and packaging configuration. Ensure compatibility with target isolation voltage requirements and thermal management constraints. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with robust isolation is required for automotive or industrial environments. Consider the 4A peak current capability and 60ns delay for driving MOSFETs or IGBTs. Evaluate the SOIC-16 package size against board space limitations and verify that the 5kVRMS isolation rating meets system safety standards.

Isolators - Gate Drivers Part Context

Part of the Si823x family of isolated gate drivers, the SI8233CB-AM leverages Skyworks' capacitive coupling technology.
