SI82F89ACC-IS1R

Isolators - Gate Drivers Overview

The SI82F89ACC-IS1R is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features a 3.75 kVrms isolation rating and supports both high-side and low-side configurations. The device operates with a supply voltage range of 3 V to 20 V and delivers a peak output current of 1.5 A. Key electrical parameters include a non-inverting logic configuration, a rise time of 16 ns, and a fall time of 22 ns. It functions within an operating temperature range of -40°C to +125°C and is housed in a 16-lead SOIC package.

Isolators - Gate Drivers Feature Summary

• Provides 3.75 kVrms reinforced insulation for safe signal transfer between isolated domains.
• Integrates two independent channels capable of driving high-side and low-side power devices simultaneously.
• Utilizes silicon dioxide (SiO2) dielectric technology to ensure long-term reliability and stable performance.

Isolators - Gate Drivers Applications

• Industrial motor drives requiring galvanic isolation
• Inverter circuits in renewable energy systems
• Isolated power supply control interfaces

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R against the manufacturer's official datasheet to confirm packaging type and pinout compatibility. Ensure that the selected variant matches the required isolation voltage and channel count for the target design. Cross-reference the ordering part number with Skyworks Solutions documentation to avoid substitution errors during procurement.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with moderate drive strength is required. The 1.5 A output current suits smaller MOSFETs or IGBTs. Consider the 16-lead SOIC footprint for PCB layout constraints. Verify that the 3.75 kV isolation level meets the safety standards of the application environment.

Isolators - Gate Drivers Part Context

This part belongs to the SI82F8x family of isolated gate drivers. It complements single-channel variants like the SI82C70 series and higher-current models such as the SI82F29AEC. The dual-channel architecture distinguishes it from single-driver parts, offering space savings for bridge configurations.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other Skyworks dual-channel drivers with similar isolation ratings, such as the SI82F89ACC-IS1. Verify pin-to-pin compatibility and electrical specifications before replacement.
