Overview
The SI83415BDA-IFR is a single-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It features a sinking output configuration and integrates an SPI interface for control. The device includes channel status indicators to provide real-time feedback on the load state. It operates within a supply voltage range of 2.25 V to 5.5 V and supports a maximum continuous output current of 2.5 A. The component is housed in a compact 32-DFN (9x9 mm) package suitable for surface-mount assembly.
Feature Summary
- Integrates digital isolation with power switching capabilities in a single component
- Provides programmable fault protection and diagnostic reporting via SPI interface
- Includes built-in channel status indicators for immediate visual or electrical feedback
Applications
- Industrial automation power distribution systems
- Isolated motor control circuits
- Smart sensor node power management
Procurement Notes
Verify the specific suffix 'IFR' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer has not discontinued this specific variant, as availability may vary by region. Ensure the ordering part number matches the required reel quantity and package orientation for automated assembly processes.
Selection Notes
Select this component when a single-channel solution with integrated isolation and SPI diagnostics is required. It is suitable for designs needing high-side or low-side sinking control with precise fault monitoring. Consider the 32-DFN footprint constraints and thermal dissipation requirements relative to the 2.5 A load capacity during system design.
Part Context
This part belongs to the Si834xx series of isolated smart switches, which combine power MOSFETs with digital isolators. The series offers various channel counts and interface options to address diverse power distribution needs in industrial and automotive environments while maintaining galvanic isolation between control and power domains.
Replacement Considerations
The SI83415BDA-IF is the non-reel version of this component. Verify pinout compatibility if substituting with other Si834xx variants, as package dimensions and terminal arrangements may differ across the family.
