SI8233BB-ASR

Isolators - Gate Drivers Overview

The SI8233BB-ASR is a dual-channel, automotive-grade isolated gate driver from Skyworks Solutions. It features capacitive coupling technology with 2500 Vrms isolation voltage and supports high-side and low-side configurations in a 16-SOIC package. The device delivers a peak output current of 4 A with propagation delays up to 45 ns and rise/fall times of 12 ns. It operates within a temperature range of -40°C to +125°C and includes an 8 V UVLO threshold.

Isolators - Gate Drivers Feature Summary

• Provides two completely isolated drivers within a single package for efficient space utilization.
• Utilizes capacitive coupling technology to ensure high electromagnetic immunity and reliability.
• Supports both high-side and low-side switching applications with robust isolation capabilities.

Isolators - Gate Drivers Applications

• Industrial inverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix ASR corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 2500 Vrms isolation rating meets your safety standards compared to higher-rated variants like the BD series. Ensure the 16-SOIC footprint matches your PCB design constraints and thermal management requirements.

Isolators - Gate Drivers Selection Notes

Select this component when automotive qualification (AEC-Q100) and 2500 Vrms isolation are sufficient for the application. Consider alternative models if higher isolation voltages or different UVLO thresholds are needed. Evaluate the 4 A peak current capability against the gate charge requirements of the target power switches to ensure adequate drive strength.
