SI8275AB-AS1

Isolators - Gate Drivers Overview

The SI8275AB-AS1 is a dual-channel, galvanically isolated gate driver from Skyworks Solutions. It operates within a supply voltage range of 2.5 V to 5.5 V and provides an isolation voltage of 2.5 kVrms. The device features a maximum propagation delay of 75 ns, with rise and fall times of 16 ns and 18 ns respectively. It supports a power dissipation of 1.2 W and functions between -40°C and +125°C. Packaged in a SOIC-16 format on a reel, it serves as a high-speed interface for power switching applications.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control logic and power switches
• Features low latency and skew for precise timing control
• Includes undervoltage lockout (UVLO) protection mechanisms

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Power supply management

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS1 against official Skyworks documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with the required SOIC-16 footprint and thermal management requirements for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation is required with strict timing constraints. Compare against single-channel variants like the SI8271 series if only one output is needed. Confirm that the 2.5 kVrms isolation rating meets the safety standards of the intended system design.

Isolators - Gate Drivers Part Context

This part belongs to the Si8275 family of isolated gate drivers designed for robust performance in noisy environments. It complements other Skyworks solutions by offering integrated UVLO and deglitching capabilities, ensuring reliable operation in demanding industrial and automotive-grade power electronics applications.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other dual-channel variants within the Si8275 series, such as the SI8275GBD-AS1, provided pinout and electrical parameters match. Verify package type and insulation ratings before substitution.
