SI83414BAA-IF

Overview

The SI83414BAA-IF is a four-channel isolated smart switch from Skyworks Solutions, designed for power distribution applications. It integrates high-side and low-side outputs with a maximum continuous output current of 700 mA per channel and an 880 mA current limit. The device features a maximum on-resistance of 300 mOhms and operates within a supply voltage range of 2.25 V to 32 V. It supports SMD/SMT mounting in a 32-DFN package and functions between -40°C and +125°C.

Feature Summary

• Integrates four independent isolated channels for flexible power distribution control
• Provides combined high-side and low-side switching capabilities within a single component
• Includes integrated current limiting protection to safeguard connected loads

Applications

• Industrial automation power distribution systems
• Isolated motor control circuits
• Smart sensor node power management

Procurement Notes

Verify the specific suffix 'BAA' against official Skyworks documentation to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with required isolation voltage ratings and thermal management solutions for the target operating environment before finalizing procurement.

Selection Notes

Select this component when four isolated channels are required with moderate current handling capabilities. Consider the 300 mOhm on-resistance for efficiency calculations and verify that the 32-DFN package fits the available PCB real estate. Confirm interface requirements match the controller logic levels.

Part Context

This part belongs to the Si834xx family of isolated smart switches. These devices combine digital isolation technology with power switching elements to simplify system design by reducing component count and board space compared to discrete solutions.

Replacement Considerations

The SI83414AAA-IF is a verified substitute within the same product family offering similar four-channel functionality.
