FUSB302BMPX

Controllers Overview

The FUSB302BMPX is a programmable USB Type-C controller with Power Delivery support, manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device integrates the physical layer of the USB BMC power delivery protocol, enabling up to 100 W of power transfer and role swaps. It features autonomous dual-role port (DRP) toggle functionality and communicates via an I2C interface. The component is packaged in a 14-lead MLP measuring 2.5 mm x 2.5 mm with a 0.5 mm pitch.

Controllers Feature Summary

• Integrates USB BMC power delivery physical layer for up to 100 W power handling
• Supports autonomous DRP toggle for host or device connection based on attachment
• Includes integrated CCx to VCONN switch with over-current limiting for full-featured cables
• Provides automatic GoodCRC response, packet retries, and soft/hard reset capabilities

Controllers Applications

• Smartphones
• Tablets
• Laptops
• Power Adapters
• Automotive systems

Controllers Procurement Notes

Verify the specific ordering suffix MPX corresponds to the 14-lead MLP package when sourcing. Confirm that the required operating temperature range aligns with the standard grade (-40°C to +85°C), as automotive-grade variants exist with different suffixes. Ensure the design accounts for the I2C interface requirements and proper thermal grounding through the exposed pad.

Controllers Selection Notes

Select this model for designs requiring low programmability with integrated PD physical layer management. It is suitable for applications needing autonomous role switching without complex external logic. Consider alternative packages like WLCSP if board space is severely constrained, or verify if the higher temperature grade variant is necessary for harsh environments.

Controllers Part Context

This component belongs to the FUSB302B series of USB Type-C controllers from onsemi. The series includes various package options such as WLCSP and MLP, along with different temperature grades. The MPX suffix specifically denotes the 14-lead MLP package configuration used in this part number.

Controllers Replacement Considerations

FUSB302BVMPX offers similar functionality but is qualified to AEC-Q100 Grade 2 with an extended temperature range of -40°C to +105°C.
