Overview
The SI83414AAA-IF is a four-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It integrates high-side and low-side N-channel MOSFETs with digital isolation. Key electrical parameters include a continuous output current of 700 mA and a current limit of 880 mA per channel. The device features a maximum on-resistance of 280 mOhms, with turn-on and turn-off times of 2.1 us and 2.2 us respectively. It operates within a supply voltage range of 2.25 V to 32 V and supports temperatures from -40°C to +125°C in a 32-pin DFN package.
Feature Summary
- Integrates four independent channels combining high-side and low-side switching capabilities with integrated digital isolation.
Applications
- Industrial power distribution systems
- Automotive electronic control units
- Isolated gate driver circuits
Procurement Notes
Verify the specific suffix 'IF' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the 32-pin DFN EP package dimensions with your PCB footprint library before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring galvanic isolation between control logic and power loads. The 700 mA current rating suits moderate load applications. Verify that the 280 mOhm on-resistance aligns with thermal management constraints. Ensure the operating voltage range covers the system's rail variations.
Part Context
This part belongs to the Si834xx family of isolated smart switches. These devices are engineered to simplify power distribution by integrating switching elements with capacitive digital isolation. The family provides solutions for reducing board space and component count in industrial and automotive environments requiring reliable signal transfer across isolation barriers.
Replacement Considerations
Consult the official Skyworks cross-reference guide for verified substitutes. Direct replacements must match the 32-pin DFN package and 700 mA current rating. Verify compatibility with existing isolation voltage ratings and control interface signals before substitution.
