Overview
The SI83401BAA-IF is a high-side power distribution switch IC from the Si834xx series, manufactured by Skyworks Solutions. It features an integrated N-channel MOSFET with a maximum on-resistance of 155 mΩ and a continuous output current rating of 700 mA. The device includes programmable current limiting set to 880 mA and operates within a supply voltage range of 2.25 V to 5.5 V for logic and 9 V to 32 V for the load. It provides overtemperature protection and is housed in a DFN-32 package suitable for surface mount applications.
Feature Summary
- Integrates a high-side power switch with low on-resistance for efficient power delivery
- Includes built-in current limiting and thermal shutdown for circuit protection
- Features isolated control interface for safe operation in noisy environments
Applications
- Industrial automation power distribution
- Automotive electronic control units
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix IF against official Skyworks documentation to confirm tape-and-reel packaging and quantity per tray. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts. Confirm lead times and availability directly with the supplier as inventory levels fluctuate.
Selection Notes
Select this component when a single-channel high-side switch with isolation is required. Compare the 700 mA current rating and 155 mΩ on-resistance against system load requirements. Consider the DFN-32 package size for PCB layout constraints. Evaluate the operating temperature range of -40°C to +125°C against environmental conditions.
Part Context
This part belongs to the Si834xx family of isolated smart switches designed for robust power management. These devices are engineered for applications requiring galvanic isolation between control and power domains. The family offers various channel configurations and current ratings to suit diverse industrial and automotive needs.
Replacement Considerations
Check Skyworks datasheets for compatible alternatives within the Si834xx series. Verify pinout compatibility and electrical specifications before substitution. Consult official replacement guides for cross-reference information.
