SI82D99BBC-IS1R

Isolators - Gate Drivers Overview

The SI82D99BBC-IS1R is a dual-channel isolated gate driver manufactured by Skyworks Solutions, Inc., designed for high-voltage power switching applications. It provides 3.75 kV isolation voltage and delivers a peak output current of 1 A per channel. The device operates with a supply voltage range of 3 V to 20 V and supports both inverting and non-inverting logic configurations. Key electrical parameters include a maximum propagation delay of 58 ns, an on-resistance (Rds On) of 8.58 mOhms, and an operating supply current of 2.04 mA. It functions within a temperature range of -40°C to +125°C and is housed in a surface-mount package.

• Integrates capacitive technology for robust signal transmission across the isolation barrier.
• Supports flexible logic control with selectable inverting or non-inverting channel configurations.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters
• Solar microinverter systems
• Uninterruptible power supplies (UPS)
• High-frequency DC-DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R confirms the reel packaging format when ordering. Ensure the procurement documentation matches the manufacturer part number SI82D99BBC-IS1R exactly. Confirm that the component meets the required RoHS compliance standards for your region. Check for any recent product change notifications that may affect pinout or specifications before finalizing the bill of materials.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel solution with 3.75 kV isolation is required for medium-power switching. The 1 A drive current is suitable for standard MOSFETs and IGBTs but may be insufficient for very large devices requiring higher peak currents. Consider the 58 ns propagation delay for timing-sensitive applications. The wide operating temperature range makes it suitable for harsh industrial environments.

Isolators - Gate Drivers Part Context

This device belongs to the Skyworks SI82 family of isolated gate drivers, which utilize proprietary capacitive coupling technology. This family offers alternatives to traditional transformer-based isolators, providing better reliability and smaller form factors. The SI82D99 variant specifically targets dual-channel applications requiring balanced performance for high-side and low-side driving.
