SI823H2AB-IS1R

Isolators - Gate Drivers Overview

The SI823H2AB-IS1R is a dual isolated gate driver from Skyworks Solutions, designed for high-side and low-side MOSFET or IGBT control. It features a 2.5 kVrms isolation rating and operates within a supply voltage range of 3 V to 5.5 V. The device supports AEC-Q100 automotive qualification and functions across an extended temperature range of -40 °C to +125 °C. Packaged in a 16-pin SOIC with a tape-and-reel configuration, it delivers a maximum propagation delay of 45 ns, with rise and fall times of 12 ns each.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against official Skyworks documentation to confirm the reel packaging format and pinout compatibility. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability. Cross-reference the datasheet revision date with your design requirements to validate parameter consistency.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel driver with 2.5 kVrms isolation is required for automotive or industrial environments. Compare propagation delays and UVLO thresholds against system timing constraints. Consider the SOIC-16 package dimensions for PCB layout compatibility and thermal management needs relative to adjacent components.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers, which utilizes Skyworks' proprietary silicon isolation technology. The series offers various isolation ratings and package options to suit different power electronics applications. The SI823H2AB variant specifically targets dual-channel applications with standard isolation levels.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes such as the SI823H2AB-IS1 if reel packaging is not strictly required. Verify that alternative parts maintain the same 2.5 kVrms isolation rating and SOIC-16 footprint to ensure mechanical and electrical interchangeability without redesigning the isolation barrier.
