NCP398FCCT1G Description

Short technical summary and product information.

The NCP398FCCT1G from ON Semiconductor is an integrated circuit designed to protect the VCONN pin in USB Type-C applications from overvoltages. It is particularly useful in scenarios where VCONN is directly powered from the VBUS supply.

 

This device features over-voltage protection up to 28V and includes on-chip low Rdson NMOS transistors with a typical resistance of 200 mΩ. It continuously monitors for undervoltage, overvoltage, and thermal events, with a high-speed comparator that can instantaneously open the power MOSFET in case of an overvoltage condition. The IC is enabled via an EN pin, which allows for forcing the internal switch off and significantly reducing current consumption.

 

Key features include Over-voltage Lockout (OVLO) and a shutdown enable input. The NCP398FCCT1G is available in a compact 4-WLCSP package measuring 0.84 x 0.84 mm with a 0.4mm pitch, making it suitable for space-constrained designs. It also has an output discharge path. Typical applications include smartphones and tablets utilizing USB Type-C.

 

The operating temperature range for this IC is -40°C to 85°C. It is supplied in a Surface Mount package, specifically a 4-UFBGA, WLCSP.
