Overview
The SI83004BF-IT is a four-channel smart power switch IC manufactured by Skyworks Solutions. It operates within a supply voltage range of 9 V to 32 V and provides an output current capability 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 applications, it is housed in a TSSOP-24 package and supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Integrates four independent high-side sourcing channels for parallel load distribution
- Provides integrated current sensing capabilities for each output channel
- Includes diagnostic features such as over-temperature protection and undervoltage warning
Applications
- Industrial power distribution systems
- Automotive body electronics control modules
- Smart relay replacement circuits
Procurement Notes
Verify the specific suffix IT against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the exact pinout and functional specifications required for the target PCB layout. Cross-reference the RoHS compliance status directly with the component documentation prior to procurement.
Selection Notes
Select this component when designing circuits requiring isolated or non-isolated high-side switching with integrated diagnostics. Evaluate the thermal performance based on the 300 mΩ on-resistance and expected load currents to determine adequate heat dissipation requirements. Confirm that the 9 V to 32 V input range aligns with the system power supply architecture.
Part Context
This device belongs to the Si830xx family of smart switches, which are designed for robust power management in harsh environments. The family typically offers configurable outputs and advanced protection mechanisms suitable for replacing mechanical relays in compact electronic designs.
Replacement Considerations
Consult the Skyworks Solutions cross-reference guide for verified equivalent parts. Ensure any substitute maintains the TSSOP-24 footprint and compatible electrical characteristics.
