SI8282BD-IS

Isolators - Gate Drivers Overview

The SI8282BD-IS is a galvanically isolated gate driver designed for SiC and IGBT applications. It features capacitive coupling technology providing 5000Vrms isolation in a 20-SOIC package. The device supports dual output configurations (inverting/non-inverting) with a peak output current of 4A. Key electrical parameters include a maximum propagation delay of 50ns, rise time of 10.5ns, and fall time of 13.3ns. It operates within a supply voltage range of 9.5V to 30V and withstands a minimum common-mode transient immunity of 35kV/µs. The component is AEC-Q100 qualified and functions between -40°C and +125°C.

Isolators - Gate Drivers Feature Summary

• Integrated DC-DC converter enables operation without external isolated power supplies.
• Capacitive coupling technology ensures high reliability and long-term stability.
• Dual-channel configuration supports both inverting and non-inverting logic options.

Isolators - Gate Drivers Applications

• Gate driving for Insulated Gate Bipolar Transistors (IGBTs)
• Automotive power electronics systems requiring AEC-Q100 qualification

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' to confirm the inclusion of the integrated DC-DC converter, as this distinguishes it from variants lacking internal power regulation. Ensure compatibility with the required isolation voltage ratings and thermal management requirements for the target application environment. Cross-reference the datasheet for pinout definitions and recommended operating conditions prior to integration.

Isolators - Gate Drivers Selection Notes

Select this component when an integrated isolated power source is required to simplify board layout and reduce external component count. The 4A peak drive current is suitable for medium-power switching applications. Consider the 20-SOIC package dimensions for PCB space constraints. Verify that the 50ns propagation delay meets the timing requirements of the control system.
