FUSB301ATM1X

Controllers Overview

The FUSB301ATM1X is an autonomous USB Type-C controller manufactured by onsemi, designed for Full Speed (FS) 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 and a low quiescent current of 7 µA. The device supports DFP, UFP, and DRP port types in compliance with the USB-C 1.1 standard. Communication with the host system is facilitated via an I2C interface. It is housed in a TMLP-12 surface-mount package and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Controllers Feature Summary

• Autonomous operation eliminates the need for continuous host processor intervention during connection events.
• Configurable I2C address allows multiple controllers to coexist on the same bus.
• Supports Dual Role Port (DRP) functionality for flexible source and sink role management.

Controllers Applications

• Portable consumer electronics requiring USB Type-C connectivity
• Peripheral devices utilizing Full Speed USB data rates
• Industrial equipment needing robust Type-C port control

Controllers Procurement Notes

Verify the specific suffix 'TM1X' against official onsemi documentation to confirm tape-and-reel specifications and marking details. Ensure compatibility with existing PCB footprints for the TMLP-12 package. Cross-reference RoHS compliance status with the latest manufacturer declarations prior to procurement.

Controllers Selection Notes

Select this component when USB Power Delivery is not required but autonomous Type-C detection is necessary. Compare against the FUSB301A series for identical core functionality. Verify that the target application operates within the specified 3 V to 5.5 V voltage range and requires only Full Speed data capabilities.

Controllers Part Context

This part belongs to the FUSB301A family of autonomous USB Type-C controllers. It shares architectural similarities with the FUSB301 but may differ in packaging or revision specifics. It serves as a cost-effective solution for basic Type-C connectivity compared to PD-enabled controllers like the FUSB307B.

Controllers Replacement Considerations

The FUSB301ATMX is a direct functional equivalent within the same product line. Verify pinout compatibility before substitution. Other models in the FUSB301A series may offer different package options or minor feature variations.
