SI8231AB-D-IS1R

Isolators - Gate Drivers Overview

The SI8231AB-D-IS1R is a dual-channel galvanically isolated gate driver from the Si823x series by Skyworks Solutions. It integrates high-side and low-side drivers in a 16-SOIC package with 2500 Vrms isolation. Key electrical parameters include a peak output current of 500 mA, maximum propagation delay of 60 ns, and rise/fall times of 20 ns. The device operates within a -40°C to +125°C temperature range and features an input voltage range of 4.5 V to 5.5 V.

Isolators - Gate Drivers Feature Summary

Provides galvanic isolation between control logic and power switches using capacitive coupling technology.
Integrates independent high-side and low-side driver channels for bridge configurations.
Delivers high electromagnetic immunity suitable for industrial environments.

Isolators - Gate Drivers Applications

Industrial motor drives
Inverter systems
Power supply gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D' indicates the standard SOIC-16 package and 'IS1R' denotes tape-and-reel packaging. Confirm that the AB variant corresponds to the 5V UVLO specification. Ensure compatibility with existing PCB footprints for 16-SOIC components before procurement.

Isolators - Gate Drivers Selection Notes

Select this component when 2500 Vrms isolation is sufficient for the application's safety requirements. The 500 mA peak drive current supports medium-power MOSFETs or IGBTs. Consider the 60 ns propagation delay for switching frequency limitations compared to faster alternatives in the same family.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which combines digital isolation with power stage driving capabilities. The family offers various isolation voltages and UVLO thresholds to match different system architectures and safety standards.

Isolators - Gate Drivers Replacement Considerations

SI8231AB-D-IS1R is listed as obsolete. The direct replacement is SI8231AB-D-IS1R (active) or SI8231AB-D-ISR depending on packaging needs. Verify pinout and electrical specifications against the active datasheet.
