FUSB302B10MPX

Controllers Overview

The FUSB302B10MPX is a programmable USB Type-C controller with Power Delivery support, manufactured by onsemi. It targets system designers implementing DRP/SRC/SNK connectors with minimal programming. The device integrates the USB BMC physical layer for PD communication up to 100 W and supports role swaps. It operates within a supply voltage range of 2.7 V to 5.5 V and functions at temperatures from -40°C to +85°C. The component is housed in a 14-lead MLP package (2.5 mm × 2.5 mm) and communicates via an I²C interface.

Controllers Feature Summary

• Integrates USB BMC Power Delivery physical layer for protocol communication

• Automotive systems

Controllers Procurement Notes

Verify the specific ordering suffix '10' against the manufacturer's official documentation to confirm the exact top mark and shipping configuration. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the part number with the latest datasheet revision to confirm compliance with current specifications.

Controllers Selection Notes

Select this component when a low-programmability solution for USB Type-C detection and PD negotiation is required. The FUSB302B10MPX is suitable for designs needing integrated BMC PHY and VCONN switching without external protocol controllers. Consider the 14-lead MLP package constraints and I²C interface requirements during schematic design. Verify compatibility with the host processor's I²C speed and interrupt handling capabilities.

Controllers Part Context

This part belongs to the FUSB302B series of programmable USB Type-C controllers. Other variants in the family include different package options like WLCSP or distinct top marks for the same MLP footprint. The series is designed to simplify Type-C implementation by handling physical layer tasks autonomously. It serves as a bridge between the Type-C connector and the system processor.

Controllers Replacement Considerations

Direct substitutes within the same package and pinout may include other FUSB302B variants such as FUSB302B01MPX or FUSB302BVMPX, provided the top mark and temperature grade align with project requirements. Verify electrical characteristics and register compatibility before substitution.
