Overview
The SI83404BAA-IFR is a four-channel isolated smart switch from Skyworks Solutions. It integrates high-side and low-side power switches with digital isolation. The device supports an input voltage range of 2.25 V to 32 V. Each channel provides a maximum output current of 700 mA with a current limit of 880 mA. The typical on-resistance is 155 mΩ. Switching times are characterized by a maximum turn-on time of 2.5 µs and a maximum turn-off time of 3.5 µs. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates four independent isolated channels combining high-side and low-side power switching capabilities.
- Provides robust common-mode transient immunity for reliable operation in noisy environments.
- Features integrated protection mechanisms including overcurrent limiting and thermal shutdown.
Applications
- Industrial motor control systems requiring isolated power distribution
- Programmable logic controller (PLC) output modules
- Inverter and converter gate drive circuits
Procurement Notes
Verify the specific suffix 'BAA' against the manufacturer datasheet to confirm pinout and electrical characteristics, as variations exist within the Si834xx family. Ensure the 'IFR' package designation matches your PCB footprint requirements. Cross-reference the component marking code with official Skyworks documentation to prevent counterfeit substitution during assembly.
Selection Notes
Select this component when four isolated outputs are required in a compact form factor. Compare the 155 mΩ on-resistance against higher-current alternatives if load demands exceed 700 mA per channel. Consider the 100 kV/µs common-mode transient immunity rating for applications with rapid voltage switching. Evaluate the 32 V maximum input voltage against system supply rails.
Part Context
This part belongs to the Si834xx series of isolated smart switches. It combines power MOSFETs with capacitive digital isolators. The series offers various channel counts and package options. The SI83404 variant specifically provides four channels. It targets industrial automation and power management applications needing galvanic isolation.
Replacement Considerations
The SI83404AAA-IFR is a documented alternative within the same series. Verify that the on-resistance and switching speed differences between the AA and BA suffixes meet design specifications before substitution.
