Overview
The SI83411BCA-IF is a single-channel isolated smart switch manufactured by Skyworks Solutions. It integrates a high-side and low-side power switch with SPI interface control and channel status indicators. The device supports an operating supply voltage range of 2.25 V to 5.5 V and delivers a maximum output current of 2 A. It features a typical on-resistance of 38 mΩ and operates within a temperature range of -40°C to +125°C. The component is housed in a DFN-32 package, designed for surface-mount installation.
Feature Summary
- Integrates isolated high-side and low-side power switching capabilities within a single channel
- Provides digital control via Serial Peripheral Interface (SPI) input
- Includes built-in channel status indicators for real-time operational feedback
Applications
- Power distribution systems requiring isolated switching
- Industrial automation control circuits
- Automotive electronic subsystems
Procurement Notes
Verify the specific suffix 'IF' against official Skyworks documentation to confirm tape-and-reel packaging specifications. Confirm that the DFN-32 package dimensions match design requirements. Check for end-of-life status or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when a single-channel isolated switch with SPI control and status indication is required. Ensure the system voltage aligns with the 2.25 V to 5.5 V operating range. Verify that the 2 A output current capacity meets load requirements and that the thermal performance supports the specified operating temperature range.
Part Context
This part belongs to the Si834xx series of isolated smart switches from Skyworks Solutions. These devices are designed for applications requiring robust power management with digital isolation. The series typically offers multiple channel configurations and interface options to suit various system architectures.
Replacement Considerations
Consult official Skyworks substitution guides for verified alternatives. Cross-reference pinout compatibility and electrical parameters if considering equivalent parts from other manufacturers.
