NCP398FCCT1G

Overview

The NCP398FCCT1G is a USB Type-C overvoltage protection controller designed to safeguard VCONN lines against high-speed overvoltage events originating from the Vbus cable. It operates within a supply voltage range of 2.4 V to 28 V and functions reliably across an industrial temperature range of -40°C to +85°C. The device is housed in a compact WLCSP-4 package with dimensions of 0.84x0.84 mm, ensuring minimal board space consumption while providing robust interface protection for USB applications.

Feature Summary

Provides dedicated protection for VCONN lines against high-speed overvoltage transients from Vbus cables
Operates with a wide input supply voltage range up to 28 V for versatile system integration
Utilizes a miniature WLCSP-4 footprint to optimize PCB real estate in portable devices

Applications

USB Type-C port protection circuits
VCONN line surge suppression
Portable electronic device interface protection

Procurement Notes

Verify the specific suffix FCCT1G corresponds to the WLCSP-4 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to implementation. Ensure the ordering part number matches the required tape-and-reel quantity specifications for your manufacturing process.

Selection Notes

Select this component when designing USB Type-C interfaces requiring specialized VCONN overvoltage defense. It is suitable for systems where standard TVS diodes may lack the necessary speed or voltage handling capabilities for transient events. Consider the small form factor for dense layout requirements in modern mobile and consumer electronics.

Part Context

This device belongs to the NCP398 series of USB interface protection controllers. It complements onsemi's portfolio of power management solutions by addressing specific signal integrity and safety concerns in USB Type-C implementations. The series focuses on protecting sensitive communication lines from electrical stress during connection events.
