SI8271ABD-IS

Isolators - Gate Drivers Overview

The SI8271ABD-IS is a single-channel, current-isolated gate driver manufactured by Skyworks Solutions. It utilizes silicon isolation technology to provide a high isolation voltage of 2.5 kVRMS. The device accepts TTL logic inputs and operates within a supply voltage range of 2.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 75 ns, with rise and fall times of 16 ns and 18 ns respectively. It delivers an output current of 4 mA and features programmable dead-time control. The component is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity (CMTI) for reliable signal transmission in noisy environments
• Programmable dead-time control to prevent shoot-through currents in power switching applications
• Integrated under-voltage lockout (UVLO) ensures safe operation by monitoring supply voltages

Isolators - Gate Drivers Applications

• Switched-mode power supplies (SMPS)
• Solar inverters
• Motor control systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' against the manufacturer's official documentation to confirm the exact isolation rating and pin configuration. Ensure that the selected variant matches the required thermal performance and packaging specifications for the target application environment. Cross-reference the datasheet revision date to guarantee compatibility with current design standards.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated gate driver with high CMTI is required. Consider the 4 mA output capability and 2.5 kVRMS isolation barrier as primary constraints. Evaluate the need for programmable dead-time and UVLO features relative to the power stage requirements. Confirm that the 8-SOIC package fits the available PCB footprint.

Isolators - Gate Drivers Part Context

This part belongs to the Si8271 series of isolated gate drivers from Skyworks Solutions. The series includes variants with different isolation ratings and packaging options. The SI8271ABD-IS specifically denotes the industrial-grade version with standard isolation characteristics and tube packaging, distinct from automotive-qualified counterparts or reel-packaged versions.

Isolators - Gate Drivers Replacement Considerations

Potential substitutes within the same family include SI8271BBD-IS and SI8261AAC-IS. Verify functional equivalence regarding isolation voltage, channel count, and package dimensions before substitution. Consult the official replacement guide for cross-referencing compatible parts.
