SI823H1AB-IM1R

Isolators - Gate Drivers Overview

The SI823H1AB-IM1R is a high-performance, automotive-grade isolated gate driver from the Si823Hx series by Skyworks Solutions. It features a single channel with capacitive coupling technology providing 2500Vrms isolation voltage. The device operates within a supply voltage range of 3 V to 5.5 V and supports a minimum common-mode transient immunity (CMTI) of 125 kV/µs. Packaged in a compact 14-DFN (5x5 mm) surface-mount format, it ensures stable operation in high dV/dt environments typical of power conversion applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IM1R corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets AEC-Q100 automotive standards if intended for vehicle applications. Ensure compatibility with the system's logic input levels and isolation voltage requirements before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with superior noise immunity is critical. The 125 kV/µs CMTI rating makes it suitable for applications with rapid voltage transitions. Consider the DFN package size for space-constrained designs requiring reliable galvanic isolation between control and power stages.

Isolators - Gate Drivers Part Context

Part of the Si823Hx family, which utilizes Skyworks' proprietary capacitive isolation technology. This series provides alternatives to traditional optocouplers, offering longer lifespan and better performance consistency. The SI823H1 variant specifically addresses single-channel high-side or low-side driving needs.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other single-channel isolated drivers from the same manufacturer with equivalent isolation ratings. Verify pinout compatibility and thermal characteristics when replacing legacy optocoupler-based solutions.
