SI83004BF-ITR

Overview

The SI83004BF-ITR is a four-channel smart power switch manufactured by Skyworks Solutions Inc. It operates within a supply voltage range of 9 V to 32 V and delivers an output current of 700 mA per channel. The device features a maximum on-resistance of 300 mΩ, with a typical turn-on time of 3.4 μs and a maximum turn-off time of 4.5 μs. Designed for surface-mount installation, it utilizes a TSSOP-24 package and supports operation across a temperature range from -40 °C to +125 °C.

Feature Summary

• Integrates four independent high-side power switches in a single compact package
• Provides parallel control capability for synchronized switching operations
• Features sourcing output architecture for direct load driving

Applications

• Industrial power distribution systems
• Automotive electronic control units
• General-purpose smart switch applications requiring isolated or non-isolated control

Procurement Notes

Verify the specific suffix 'ITR' against official Skyworks documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering part number matches the exact electrical characteristics and package type required for your design. Cross-reference the manufacturer's latest datasheet to validate any revisions or updates to the component specifications before finalizing procurement.

Selection Notes

Select this component when a multi-channel power distribution solution is required with integrated switching capabilities. The 700 mA output current and low on-resistance make it suitable for moderate load applications. Consider the TSSOP-24 package constraints and thermal management requirements associated with the specified operating temperature range during PCB layout.

Part Context
