SI8233BD-D-ISR

Isolators - Gate Drivers Overview

The SI8233BD-D-ISR is a dual-channel isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It utilizes silicon isolation technology to provide up to 5kVRMS withstand voltage per UL1577 certification. The device features a maximum propagation delay of 60ns and peak output currents of 4A. It operates with a supply voltage range of 9.4V to 24V and supports switching frequencies up to 8MHz. The component is housed in a 16-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Isolators - Gate Drivers Feature Summary

• High electromagnetic interference immunity with >400mV input hysteresis
• Integrated overlap protection and programmable dead-time control
• Supports independent ground references or positive/negative voltage connections

Isolators - Gate Drivers Applications

• Motor drive and control systems
• Industrial power management circuits
• Lighting applications requiring galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D' indicates the correct isolation rating and pinout configuration against the official datasheet. Confirm AEC-Q100 qualification requirements if deploying in automotive environments. Ensure the 16-SOIC package dimensions match the target PCB footprint. Cross-reference the manufacturer part number with distributor listings to confirm current production status and lead times.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and fast switching speeds are required for IGBT or MOSFET gates. The 5kVRMS isolation level suits applications with significant potential differences between control and power domains. Consider the 4A peak drive capability for medium-power switches. Verify that the TTL-compatible input logic levels align with the system's microcontroller or FPGA outputs.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which are designed for high-performance industrial and automotive applications. The series offers a balance of integration, small form factor, and robust isolation performance. It replaces older discrete isolation solutions by combining driver stages with digital isolation in a single compact package.

Isolators - Gate Drivers Replacement Considerations

Check for SI8233BB-D-ISR if only 2.5kVRMS isolation is sufficient. Verify SI8233AD-D-IS for alternative packaging options like tubes instead of reels.
