SI8274GB4D-IS1R

Isolators - Gate Drivers Overview

The SI8274GB4D-IS1R is a single-channel galvanically isolated gate driver from Skyworks Solutions, packaged in a 16-SOIC surface-mount format. It provides high common-mode transient immunity with an isolation voltage of 2.5 kVrms and supports PWM input signals with deglitching capabilities. The device features a maximum propagation delay of 105 ns, with rise and fall times of 16 ns and 18 ns respectively. It operates within a temperature range of -40°C to +125°C and is AEC-Q100 qualified for automotive applications.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity for reliable signal transmission in noisy environments
• Integrated deglitching functionality to filter out spurious PWM input pulses
• AEC-Q100 qualification ensuring robustness for demanding automotive electronic systems

Isolators - Gate Drivers Applications

• Automotive powertrain control modules requiring isolated switching
• Motor drive systems utilizing high-side and low-side configurations
• Industrial inverters and converters needing galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1R' confirms the reel packaging variant and 3 V UVLO threshold against the official Skyworks datasheet. Ensure the ordering part number matches the required logic type and output configuration. Cross-reference the RoHS compliance status and moisture sensitivity level prior to procurement to maintain supply chain integrity.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with integrated deglitching is required for PWM applications. The 2.5 kVrms isolation rating suits standard industrial and automotive isolation barriers. Consider the 105 ns propagation delay and 4 mA output current limits against load requirements. The SOIC-16 package facilitates PCB layout integration compared to larger form factors.

Isolators - Gate Drivers Part Context

This part belongs to the Si8274 series of galvanically isolated gate drivers designed for high-speed switching applications. The series emphasizes low latency and skew while maintaining high CMTI. The SI8274GB4D-IS1R specifically denotes the reel-packaged version with defined UVLO thresholds, distinct from tube-packaged variants like the SI8274GB4D-IS1.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si8274 variants such as SI8274DB4D-IS1 or SI8274BB4D-IS1, provided their specific UVLO thresholds and packaging formats align with the design constraints.
