NCP398 USB Type-C VCONN Overvoltage Protection IC The NCP398 is an overvoltage protection device. It protects VCONN against overvoltages in applications where VCONN is directly derived from the VBUS supply. www.onsemi.com At power up, the integrated power MOSFET is automatically controlled to reduce inrush current. The IC continuously monitors undervoltage, overvoltage and thermal events. In case of MARKING overvoltage, a very high speed comparator opens the power DIAGRAMS MOSFET instantaneously. The part is enabled through the EN pin. A high level on this pin allows forcing off the internal switch and drastically decreases the AV M UDFN6 current consumption of the NCP398 core.
