SI8220BB-A-IS

Isolators - Gate Drivers Overview

The SI8220BB-A-IS is a single-channel isolated gate driver from Skyworks Solutions, utilizing capacitive coupling technology for signal transmission. It features a 2500Vrms isolation voltage and operates within a temperature range of -40°C to +125°C. The device provides peak output currents of 1.5A (high) and 2.5A (low), with typical rise and fall times of 20ns. Propagation delays are specified at a maximum of 60ns for low-to-high and 40ns for high-to-low transitions. It is housed in an 8-SOIC package and holds AEC-Q100 qualification.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling architecture ensures robust signal integrity across the isolation barrier.
• High common-mode transient immunity protects against noise in switching environments.
• Integrated shutdown capability allows for precise control of the output state.
• Dual-output configuration supports both inverting and non-inverting logic.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Power supply gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'BB' confirms the 8-pin SOIC package variant, distinct from other pin counts in the series. Confirm AEC-Q100 automotive grade status if required for the target application. Check current lifecycle status as some listings indicate obsolescence for this specific suffix combination. Ensure compatibility with the intended input logic levels and output drive requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with moderate speed and 2500Vrms isolation is sufficient. Compare propagation delay specifications against system timing constraints. Evaluate the 8-SOIC footprint against PCB space limitations. Consider the 2.5A peak current capability relative to the target MOSFET or IGBT gate charge requirements.

Isolators - Gate Drivers Part Context

This part belongs to the SI822x family of isolated gate drivers. It shares architectural similarities with other members like the SI8220DD-D-IS but differs in package type and specific electrical characteristics. The family emphasizes reliability through capacitive isolation technology, offering alternatives to traditional optocouplers in power electronics applications.
