SI83418ADA-IF

Overview

The Si83418ADA-IF is a four-channel isolated smart switch IC from Skyworks Solutions, designed for power distribution applications. It supports both high-side and low-side switching configurations with an output current of 700 mA per channel and a current limit of 880 mA. The device features a maximum on-resistance of 155 mOhms, with turn-on and turn-off times capped at 2.7 us. It operates within dual voltage ranges: 2.25 V to 5.5 V and 9 V to 32 V. The component is housed in a DFN-32 package, suitable for surface mount installation, and functions reliably across a temperature range of -40 C to +125 C.

Feature Summary

Provides four independent channels for isolated power switching
Supports flexible high-side and low-side load control
Integrates SPI interface for digital control and status monitoring

Applications

Industrial automation power distribution
Isolated smart switch implementations
Power management in harsh environments

Procurement Notes

Verify the specific suffix 'IF' against official Skyworks documentation to confirm pinout and packaging details. Ensure compatibility with required isolation standards and thermal management solutions for the DFN-32 package. Cross-reference the datasheet for any recent revisions that may impact design-in parameters or recommended operating conditions.

Selection Notes

Select this component when four isolated channels are required for precise power routing. Consider the 700 mA continuous output capability and 155 mOhm resistance for efficiency requirements. Verify that the SPI interface aligns with the system's control architecture and that the wide input voltage range accommodates the target supply rails.

Part Context

This part belongs to the Si834xx series of isolated smart switches. It complements other variants like the Si83418ADA-KIT evaluation board, which aids in assessing performance. The series focuses on providing robust, digitally controlled power switching with integrated protection features for demanding industrial and commercial applications.
