SI82E89ACE-IS3R

Isolators - Gate Drivers Overview

The SI82E89ACE-IS3R is a dual-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features a 6 kV isolation rating and supports both high-side and low-side configurations in a non-inverting logic setup. The device operates with a supply voltage range of 5 V to 30 V and accepts input signals between 3 V and 20 V. Key electrical parameters include a maximum propagation delay of 40 ns, with rise and fall times of 8.3 ns and 8.6 ns respectively. It functions within an operating temperature range of -40°C to +125°C and utilizes a SOIC-14 surface-mount package.

Isolators - Gate Drivers Feature Summary

• Provides 6 kV reinforced isolation for safe signal transmission across potential barriers.
• Integrates two independent channels capable of driving high-side and low-side switches simultaneously.
• Delivers fast switching performance with sub-10 ns rise and fall times for efficient power control.
• Supports wide supply voltage ranges to accommodate various gate drive requirements.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters
• Switched-mode power supplies (SMPS)
• High-frequency AC/DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ACE' against the manufacturer's official datasheet to confirm pinout compatibility and insulation specifications. Ensure that the SOIC-14 package dimensions match your PCB footprint design. Confirm that the 6 kV isolation rating meets the safety standards required for your specific application environment. Check for moisture sensitivity levels if storage conditions are not controlled.

Isolators - Gate Drivers Selection Notes

Select this component when high voltage isolation and precise timing are critical. The dual-channel architecture simplifies board layout for half-bridge or full-bridge topologies. Consider the 40 ns propagation delay limit for system timing budgets. The wide operating temperature range ensures reliability in harsh industrial environments. Verify input logic compatibility with your microcontroller or FPGA output levels.
