• High-speed signal transmission with 30 ns maximum propagation delay
• Robust thermal performance supporting operation up to +125°C
• Integrated protection against false triggering via common-mode transient immunity

Gate Driver Applications

• Motor control systems requiring isolated gate driving
• Industrial power conversion topologies
• Inverter circuits in renewable energy applications
• Solid-state transformer designs

Gate Driver Procurement Notes

Verify the manufacturer designation carefully, as Skyworks Solutions, Inc. is the original designer while Econ Connect may serve as a distributor or secondary source. Confirm the specific suffix 'IMR' corresponds to the tape-and-reel packaging format. Ensure compatibility with your PCB footprint for the 14-DFN package. Cross-reference the datasheet version to confirm parameter consistency, particularly regarding insulation ratings and thermal characteristics.

Gate Driver Selection Notes

Select this component when dual-channel isolation is required for synchronous rectification or half-bridge applications. The 30 ns propagation delay suits medium-frequency switching operations. Verify that the 30 V output voltage rating aligns with the target gate drive requirements. Consider the 14-DFN package size for space-constrained designs. Ensure the system design accounts for the 2.5 kVrms isolation barrier requirements.

Gate Driver Part Context

This part belongs to the SI823hx series of isolators, which are designed for robust performance in noisy environments. The series utilizes silicon dioxide (SiO2) isolation technology to provide reliable signal transmission across isolation barriers. The SI823H6AB variant specifically addresses dual-channel needs, offering independent high-side and low-side drive capabilities within a compact form factor suitable for modern power electronics.
