Overview
The SI83401BBA-IFR is a single-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It features an N-channel output capable of handling up to 2.5A load current with a voltage range of 9V to 32V. The device operates on a supply voltage of 2.25V to 5.5V and utilizes a parallel interface. Packaged in a 32-VFDFN exposed pad format, it supports surface mount installation and functions within a temperature range of -40°C to 125°C.
Feature Summary
- Integrates isolation capabilities for safe high-side switching operations
- Provides single-channel control with sourcing output configuration
- Supports parallel interface communication for system integration
Applications
- Industrial power distribution systems
- Automotive electronic control units
- Isolated gate driver circuits
Procurement Notes
Verify the specific suffix IF indicates tape and reel packaging when ordering. Confirm that the parallel interface requirement matches your system design constraints. Ensure thermal management solutions are adequate for the DFN package given the operating temperature range. Check RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a single-channel isolated switch with 2.5A capacity is required. Compare against other Si834xx variants if multiple channels or different current ratings are needed. Verify that the 9V to 32V load voltage range aligns with your application's power requirements. Consider the parallel interface compatibility with your controller logic levels.
Part Context
This part belongs to the Si834xx family of isolated smart switches from Skyworks Solutions. These devices are engineered for robust power management in demanding environments. The BBA variant specifically denotes the single-channel sourcing configuration with parallel interface capabilities, distinguishing it from multi-channel or digital interface counterparts in the same series.
Replacement Considerations
Check Skyworks documentation for direct pin-compatible alternatives within the Si834xx series. Verify electrical parameters such as current rating and voltage limits before substituting. Ensure the replacement part supports the same parallel interface protocol.
