FUSB301ATMX-SN00362

Controllers Overview

The FUSB301ATMX is a USB Type-C controller IC from onsemi, designed for full-speed data transfer without Power Delivery support. It operates within a supply voltage range of 3 V to 5.5 V, with a typical operating voltage of 3.3 V. The device supports DFP, UFP, and DRP port types and complies with the USB-C 1.1 standard. Key electrical parameters include a maximum operating temperature of +85 °C, a minimum of -40 °C, and an operating supply current of 7 uA. It utilizes I2C and USB interfaces and is housed in a TMLP-12 package.

Controllers Feature Summary

• Supports Dual Role Port (DRP) functionality for flexible connection management
• Integrates Type-C CC pin logic for cable orientation detection
• Provides low-power standby mode suitable for battery-operated devices

Controllers Applications

• Mobile phone charging ports
• Portable electronic device connectivity
• Peripheral interface hubs

Controllers Procurement Notes

Verify the exact suffix against official datasheets, as variations may indicate specific tape-and-reel configurations or regional compliance markings. Confirm RoHS status through manufacturer documentation. Ensure compatibility with existing PCB footprints for the TMLP-12 package before finalizing orders.

Controllers Selection Notes

Select this component when USB Power Delivery is not required but Type-C physical layer compliance is necessary. Compare against other FUSB301 variants for package availability. Verify that the 7 uA standby current meets system power budget requirements. Check interface compatibility with the host microcontroller's I2C capabilities.

Controllers Part Context

This part belongs to the FUSB301A series of USB Type-C controllers. It serves as a foundational solution for basic Type-C connectivity, distinguishing itself from PD-enabled counterparts by omitting complex power negotiation logic. It is commonly used in applications where simple plug-and-play functionality is sufficient.

Controllers Replacement Considerations

Direct substitutes include other FUSB301A variants with compatible packages. Cross-reference pinouts carefully when considering alternative manufacturers' Type-C controllers to ensure functional equivalence.
