SI82D89AEC-IS1

Isolators - Gate Drivers Overview

The SI82D89AEC-IS1 is a dual-channel isolated gate driver manufactured by Skyworks Solutions, Inc. It provides high-voltage isolation of 3.75 kV with a peak output current capability of 1 A per channel. The device supports both high-side and low-side configurations in an inverting or non-inverting logic setup. Operating from a supply voltage range of 3 V to 20 V, it features fast switching characteristics with rise and fall times of 8.3 ns. The component is housed in a DFN-13 surface-mount package and operates within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides robust 3.75 kV reinforced insulation for safe signal transfer between control and power domains.
• Delivers symmetrical propagation delay and fast switching speeds to minimize cross-conduction risks in half-bridge applications.
• Integrates independent high-side and low-side drivers with configurable input logic for flexible system design.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters
• Solar microinverters and string inverters
• Uninterruptible power supplies (UPS)
• Battery management systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1 against the manufacturer's official datasheet to confirm pinout compatibility and isolation ratings. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the revision history for any updates to electrical parameters or mechanical dimensions before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 3.75 kV isolation is required for medium-power switching applications. Consider the 1 A output current capability relative to the target MOSFET or IGBT gate charge requirements. Evaluate the DFN-13 package size constraints against available board space and thermal dissipation needs.

Isolators - Gate Drivers Part Context

This device belongs to the SI82 family of isolated gate drivers from Skyworks Solutions. It complements other variants like the SI82D89AEE-IS3 which offers higher 6 kV isolation but uses a different SOIC-14 package. The SI82 series focuses on providing reliable galvanic isolation for power electronics while maintaining compact form factors suitable for modern industrial and energy conversion designs.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include the SI82D89AEE-IS3 for applications requiring higher 6 kV isolation, though the package changes from DFN-13 to SOIC-14. For similar 3.75 kV isolation with identical functionality, verify availability of the base SI82D89AEC model with appropriate packaging suffixes.
