Overview
The SI83404BBA-IFR is a four-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It integrates high-side and low-side output configurations with parallel input architecture. The device supports an operating supply voltage range of 2.25 V to 32 V and delivers a continuous output current of 700 mA per channel. Key electrical specifications include a maximum on-resistance of 280 mΩ, a current limit of 880 mA, a maximum turn-on time of 2.3 µs, and a maximum fall time of 2.9 µs. It operates within a temperature range of -40°C to +125°C and utilizes a surface-mount package.
Feature Summary
- Integrates four independent channels with parallel input capability for simplified circuit design.
- Provides combined high-side sourcing and low-side sinking output configurations.
- Includes integrated channel status and low voltage indicators for system monitoring.
- Features digital isolation between control inputs and power outputs.
Applications
- Industrial power distribution systems
- Automotive electronic control units
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix 'IFR' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required isolation voltage ratings and thermal management requirements for the target application environment before finalizing procurement.
Selection Notes
Select this component when a multi-channel solution with integrated isolation and status feedback is required. Compare the 280 mΩ on-resistance and 700 mA current rating against load requirements. Consider the parallel input feature if signal routing complexity needs reduction in dense PCB layouts.
Part Context
This part belongs to the Si834xx family of isolated smart switches. It complements variants like the SI83404AAA-IFR by offering similar functional capabilities with potential differences in packaging or reel configuration. The series is designed for robust power switching in noisy environments requiring galvanic isolation.
Replacement Considerations
The SI83404AAA-IFR is a documented alternative within the same product family. Verify pinout compatibility and specific parameter tolerances such as on-resistance and timing characteristics before substitution.
FAQ
What output configurations does the SI83404BBA-IFR support?
It supports both high-side sourcing and low-side sinking output configurations across its four channels.
Does the device provide status feedback?
Yes, it includes integrated channel status and low voltage indicators for each output.
