FUSB308BVMPX

Controllers Overview

The FUSB308BVMPX is an automotive-grade USB Type-C Port Controller with USB Power Delivery capabilities, manufactured by onsemi. It targets system designers implementing up to four TCPCs. The device complies with USB PD Interface Specification Rev 1.0 and USB Type-C Rev 1.3 standards. Key electrical parameters include a supply voltage range of 2.7 V to 5.5 V, operating temperature from -40°C to +105°C, and a 16-lead QFN package (WQFN-16). It features integrated Type-C detection, autonomous BMC Power Delivery handling, dual-role functionality, and two VBUS source controls.

Controllers Feature Summary

• Autonomous USB-PD handling offloads the microprocessor
• Integrated Type-C Rev 1.3 manual attach/detach detection
• Dual-role port support with automatic DRP toggling
• Built-in 10-bit ADC for precise VBUS monitoring

Controllers Applications

• Desktop computing systems
• Wall adapters
• Automotive infotainment and charging systems

Controllers Procurement Notes

Verify the specific suffix 'V' indicates automotive qualification (AEC-Q100) and extended temperature range (-40°C to +105°C). Confirm the package type is WQFN-16. Ensure the I2C address configuration matches the target design requirements before ordering.

Controllers Selection Notes

Select this component for designs requiring autonomous USB-PD state machine management to reduce CPU load. It is suitable for applications needing multiple port controllers due to its selectable I2C addresses. Verify compatibility with the host TCPM firmware regarding the supported SOP* types and message handling.

Controllers Part Context

The FUSB308B belongs to onsemi's FUSB30x series of USB Type-C controllers. The 'V' suffix in FUSB308BVMPX denotes the automotive grade variant, distinguishing it from commercial versions like the FUSB308BMPX. It shares functional similarities with the FUSB307B but offers specific packaging and qualification differences.

Controllers Replacement Considerations

The FUSB308BMPX is a commercial grade alternative with similar functionality but different temperature ratings. Check if the application requires automotive qualification; if not, the MPX version may be available. No direct cross-brand substitutes are confirmed in the provided documentation.
