Product Introduction

Overview

The NCP398FCCT1G, produced by onsemi, is an advanced USB Type-C VCONN overvoltage protection IC designed to safeguard against overvoltages in applications where VCONN is directly derived from the VBUS supply. This device integrates several key features to ensure reliable and safe operation, including overvoltage protection, undervoltage lockout, and thermal shutdown protection. The NCP398FCCT1G is available in a compact WLCSP4 package, measuring 0.84 x 0.84 mm, making it ideal for space-constrained designs.

Q & A

  1. What is the primary function of the NCP398FCCT1G?

    The NCP398FCCT1G is an overvoltage protection IC designed to protect VCONN against overvoltages in USB Type-C applications.

  2. What is the maximum input voltage the NCP398FCCT1G can handle?

    The maximum input voltage is 28 V.

  3. What is the typical on-chip Rdson value of the NMOS transistors?

    The typical on-chip Rdson value is 200 mΩ.

  4. How does the NCP398FCCT1G handle overvoltage conditions?

    During an overvoltage condition, the internal comparator opens the power MOSFET instantaneously to protect the connected system.

  5. What is the purpose of the EN pin on the NCP398FCCT1G?

    The EN pin is used to enable or disable the device. A high level on this pin forces the internal switch off and reduces current consumption.

  6. What is the thermal shutdown protection feature in the NCP398FCCT1G?

    The thermal shutdown protection opens the internal NMOS FET when the junction temperature exceeds 150°C to prevent overheating.

  7. How does the auto-discharge feature work in the NCP398FCCT1G?

    The auto-discharge feature ensures that the output is automatically discharged when the device is disabled or when the input voltage drops below the UVLO threshold.

  8. What are the typical applications of the NCP398FCCT1G?

    The NCP398FCCT1G is typically used in USB Type-C applications, smartphones, and tablets.

  9. What is the operating ambient temperature range of the NCP398FCCT1G?

    The operating ambient temperature range is −40°C to +85°C.

  10. Is the NCP398FCCT1G RoHS compliant?

    Yes, the NCP398FCCT1G is RoHS compliant.
