Overview
The SI83414BCA-IFR is a four-channel isolated smart switch from Skyworks Solutions Inc., designed for power distribution applications. It integrates high-side and low-side N-channel MOSFETs with SPI digital isolators, offering 700 mA output current per channel and an 880 mA current limit. The device operates within a supply voltage range of 2.25 V to 32 V and features a maximum on-resistance of 280 mΩ. It supports operating temperatures from -40°C to +125°C and utilizes a 32-DFN (9x9 mm) package.
Feature Summary
- Integrates four independent channels combining isolated drivers with high-side and low-side power switches
- Provides galvanic isolation via integrated SPI digital isolators with high common-mode transient immunity
- Supports bidirectional current flow through combined sourcing and sinking output configurations
- Includes built-in protection mechanisms such as overcurrent limiting and thermal shutdown
Applications
- Industrial automation motor control systems
- Programmable logic controller (PLC) I/O modules
- Power distribution units in telecommunications infrastructure
- Automotive body control modules requiring isolated switching
Procurement Notes
Verify the specific suffix 'IFR' indicates tape-and-reel packaging configuration when ordering. Confirm that the BCA variant matches the required pinout and thermal pad specifications for your PCB layout. Ensure compatibility with SPI communication protocols used in your system design before finalizing procurement.
Selection Notes
Select this component when four isolated channels are required in a compact footprint. Compare against similar Skyworks models like SI83404 or SI83414 variants based on exact timing requirements and package constraints. Verify that the 280 mΩ on-resistance meets your power dissipation limits under maximum load conditions.
Part Context
This part belongs to Skyworks' Si834xx family of isolated smart switches, which combine power switching capabilities with digital isolation technology. The family offers various channel counts and package options to address diverse power distribution needs in industrial and automotive environments while maintaining signal integrity across isolation barriers.
Replacement Considerations
Consider SI83414AAA-IF or SI83404AAA-IFR as potential alternatives if different packaging or minor parameter variations are acceptable. Verify functional equivalence regarding isolation voltage ratings and current handling capabilities before substitution.
