Overview
The FSA9688UCX is a USB Type-C receptacle detection controller manufactured by onsemi. It operates within a supply voltage range of 1.65V to 3.6V and supports data rates up to 480Mbps. The device features an integrated 20kΩ pull-down resistor for CC line termination and includes overvoltage protection rated at 20V. It utilizes a WLCSP-12 package with dimensions of 1.4mm x 1.4mm x 0.47mm. The component functions across a temperature range of -40°C to +85°C, providing reliable detection for USB Type-C connectors in portable applications.
Feature Summary
- Integrated USB Type-C receptacle detection logic
- Built-in 20kΩ pull-down resistor for CC lines
- Overvoltage protection up to 20V
- Supports high-speed data transmission up to 480Mbps
Applications
- USB Type-C port detection in smartphones
- Tablet computer charging interfaces
- Portable electronic device connectivity modules
Procurement Notes
Verify the specific suffix 'UCX' corresponds to the WLCSP-12 packaging and tape-and-reel quantity requirements. Confirm that the operating voltage range aligns with the target system's power rail specifications. Ensure ESD protection ratings meet the intended application environment standards before finalizing procurement orders.
Selection Notes
Select this component when designing USB Type-C interfaces requiring dedicated receptacle detection rather than full role swap functionality. Compare against alternatives based on package size constraints and required CC line termination resistance values. Evaluate thermal performance if the device will operate near the upper limit of the specified temperature range.
Part Context
This part belongs to onsemi's FSA series of analog switches and signal routing components. It complements other USB interface solutions by handling the specific control logic for Type-C connector presence. The series focuses on compact form factors suitable for space-constrained mobile devices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing PCB footprints and control signals if considering alternative manufacturers or updated revisions from onsemi.
