Overview
The SI83414BAA-IFR is a four-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It integrates high-side and low-side switches with independent channel control. The device supports a supply voltage range of 2.25 V to 32 V and delivers up to 700 mA continuous output current per channel. Key electrical specifications include a maximum on-resistance of 280 mΩ and an internal current limit of 880 mA. Operating characteristics feature a maximum turn-on time of 2.3 µs and a maximum turn-off time of 2.9 µs. The component operates within a temperature range of -40°C to +125°C and utilizes a surface-mount package.
Feature Summary
- Provides four independent channels for isolated high-side and low-side switching capabilities
- Integrates overcurrent protection with defined internal current limiting thresholds
- Features fast switching speeds with microsecond-level rise and fall times
Applications
- Industrial power distribution systems requiring galvanic isolation
- Smart switch configurations in automated control equipment
- Power management modules in harsh environment electronics
Procurement Notes
Verify the specific suffix 'IFR' indicates tape-and-reel packaging when sourcing components. Confirm that the BAA variant matches the required sinking and parallel channel configuration. Ensure compatibility with the intended isolation voltage requirements and thermal management solutions for the operating temperature range.
Selection Notes
Select this component for applications requiring multiple isolated outputs with integrated protection. Compare against the SI83414AAA-IFR if different timing parameters or warning features are needed. Evaluate the 280 mΩ on-resistance impact on thermal performance at full load conditions.
Part Context
This part belongs to the Si834x family of isolated smart switches from Skyworks Solutions. These devices combine power switching with digital isolation to simplify system design. The family offers various channel counts and control options for diverse power distribution needs.
Replacement Considerations
The SI83414AAA-IFR is a related model within the same series. Verify functional equivalence regarding channel independence and warning signals before substitution.
