NCP398 Datasheet (ON Semiconductor) - USB Type-C VCONN Overvoltage Protection IC

NCP398, USB Type-C VCONN Overvoltage Protection IC

Pin Pin Name Type Description A1 OUT OUTPUT Output voltage pin.

The OUT pin must be connected to the circuitry that is to be protected (VCONN rail).

B1 EN I/O Enable pin bar.

The device enters in shutdown mode when this pin is tied high in which case the output is disconnected from the i

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.

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 overvoltage, a very high speed comparator opens the power MOSFET instantaneously.

The part is enabled through t
