SI82D89AGC-IS1

Isolators - Gate Drivers Overview

The SI82D89AGC-IS1 is a dual-channel isolated gate driver manufactured by Skyworks Solutions Inc. It features capacitive coupling technology for signal and power isolation, rated at 3750 Vrms. The device provides 1 A peak output current for each channel and operates within a supply voltage range of 3 V to 20 V. It is housed in a 16-lead SOIC package with wide body (SOIC-16W). The driver supports non-inverting logic configuration and includes a shutdown function. It is designed for high-speed switching applications requiring robust galvanic isolation between control and power stages.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'GC' indicates the 16-SOIC wide body package and 'IS1' denotes the tape and reel packaging variant when ordering. Confirm that the 3750 Vrms isolation rating meets the safety requirements of your target application standard. Ensure ESD handling precautions are followed due to the sensitivity of the capacitive isolation interface. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel solution with high isolation voltage is required for driving IGBTs or MOSFETs. Compare propagation delay and peak current capabilities against similar models like the SI82E89 series if higher speed or different packaging is needed. Consider the SOIC-16W footprint constraints during PCB layout. Verify that the non-inverting configuration aligns with the control logic signals from the microcontroller or DSP.

Isolators - Gate Drivers Part Context

This part belongs to the Skyworks SI82xx family of isolated gate drivers, which utilize silicon dioxide (SiO2) capacitive isolation technology. This family offers superior performance over traditional transformer-based isolators in terms of size, weight, and reliability. The SI82D89AGC-IS1 specifically targets applications needing two independent isolated channels with moderate drive strength and high voltage isolation.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other Skyworks SI82D89 variants with different packaging options such as SI82D89AE or SI82D89BC. Check equivalent parts from other manufacturers only if they match the 3750 Vrms isolation, 1 A drive current, and 16-SOIC package dimensions. Verify pinout compatibility before substitution.
